IgA: 70-300 mg/dL Alexandra Voinescu, Kevin J. Martin, in Nutritional Management of Renal Disease, 2013. Search for phosphatonin in patients with TIO led to the identification of fibroblast growth factor- 23 (FGF-23). An acidic urine can deter bacterial colonization while a urine high in Alkaline can be caused by tubular defects. Hemoglobin are proteins in red blood cells that transmits oxygen to the body’s vital organs and transports carbon dioxide from organs to your lungs. Glucose measures our blood sugar and determines if the patient is within the criterion for diabetes. Subsequent studies in opossum kidney cells performed by several laboratories demonstrated that increasing dopamine synthesis inhibits phosphate transport by multiple mechanisms including activation of DA1 and DA2 receptors (14, 189, 237). White blood cell count is a test that measures the number of white blood cells in the body. On the other hand, Pth−/− fetuses have elevated serum phosphorus levels, reiterating the importance of PTH in fetal phosphate homeostasis. A patient with low RBC count can have a condition called aplastic anemia. As FGF23 decreases 1,25 vitamin D levels, it is important that intact FGF23 levels remain low in the early postpartum period to prevent a decrease in 1,25 vitamin D levels. Higher amounts may be required in patients with diabetes or chronic alcoholism. ... Cartier L, Sheldon S, et al.

The phosphate urine test measures the amount of phosphate in a sample of urine collected over 24 hours (24-hour urine test). Urinalysis often involves three stages, the first is the visual exam, followed by the dipstick test, and lastly the microscopic exam. Copyright © 1993-2020 Renal proximal tubules also synthesize serotonin from 5-hydroxytryptophan by the same enzyme that converts L-DOPA to dopamine. Effects of exogenous and endogenous agents on Na+-Pi cotransport are expressed as % difference (decrease) from basal values denoted by dotted line. Moreover, no change of the type IIa Na/Pi cotransporter protein abundance in BBMV was detected. These will be discussed in detail later in this chapter. Excess PTH directly decreases renal phosphate reabsorption, leading to increased renal phosphate excretion and hypophosphatemia. In addition to FGF-23, other phosphatonins have been identified: secreted frizzled-related protein 4 (sFRP4), matrix extracellular phosphoglycoprotein (MEPE), fibroblast growth factor-7 (FGF-7) [37–44].

Measuring platelet count is important in checking for patient tendencies for bleeding and thrombosis. 95th Percentile. Autocrine/paracrine regulation of renal Na(+)-phosphate cotransport by dopamine. From the TRP, the tubular threshold maximum for phosphorus per glomerular filtration rate (TMP/GFR) can be derived using a nomogram developed by Walton and Bijvoet [53,54] (Fig. RTRP1 : The tubular reabsorption of phosphate (TRP) is the fraction (or percent) of filtered phosphorus that is reabsorbed by renal tubules. It determines the percentage of blood blood that is composed of red blood cells. Normal. 12.9 – 42.0 mmol/24h. Hemoglobin is often expressed in grams per deciliter (g/dL). Iron, serum: 60-160 μg/dL Results of the 24h creatinine test are typically reported in g/24h (grams of creatinine in the urine over 24 hours). Refrigerated 6 month stability. From: Genetics of Bone Biology and Skeletal Disease, 2013, Christopher Symonds MD, Joshua Buse PhD, in Endocrine Biomarkers, 2017. The diagnosis is made by the findings of low or low-normal serum phosphate, high calcium in urine, high urinary phosphate, and high serum Vitamin D3 levels with normal serum calcium and parathyroid hormone (PTH) levels 22). Just 5 mL of blood is enough to perform a wide range of clinical tests. FIGURE 6. Diuretics, particularly those acting on the proximal tubule, may cause hypophosphatemia. Normal. Transport Info. † Significant difference (p <.05) compared with values from PTH. Northern blot analysis indicated that fasting for 48 hours did not result in a decrease of renal expression of NaPi IIa or NaPi III mRNA (13, 43). Infusion of isoproteronol markedly enhances renal phosphate reabsorption in normal rats and in hypophosphatemic mice (188, 317). FGF exerts its biological functions by binding and activation of its cognate FGF receptor (FGFR) in the presence of klotho, a type I membrane receptor with homology to beta-glycosidases [50,51]. Ingrid A. Holm, ... Thomas O. Carpenter, in Pediatric Bone (Second Edition), 2012. A patient with low levels of hemoglobin has anemia. Phosphorus, Urine - per volume: 400-1300 mg/d Phosphorus/Creatinine Ratio, Urine: Male: 7-9 years: 165-1682 mg/g 10-12 years: 144-1234 mg/g 13-15 years: 101-1134 mg/g 16-17 years: 68-874 mg/g Female: 7-9 years: 153-1443 mg/g 10-12 years: 142-1321 mg/g 13-15 years: 81-930 mg/g 16-17 years: 58-846 mg/g In children, the normal range for serum phosphorus levels is higher than that in adults. Furthermore, phosphate-replete OK cells produced more dopamine from L-DOPA than phosphate-deprived cells (113). Hemoglobin are high in iron, which means they are responsible for the bright red color of blood. Heini Murer, ... Jürg Biber, in Seldin and Giebisch's The Kidney (Fourth Edition), 2008. Its measurement is useful when evaluating patients with hypophosphatemia. By continuing you agree to the use of cookies. The enzyme that converts L-DOPA to dopamine is located exclusively in the proximal convoluted and straight tubules, also the primary sites of phosphate reabsorption. High protein content in urine can be an indication of one the following conditions: high blood pressure, lupus nephritis, diabetic nephropathy, hemolysis or multiple myeloma. When doing a urinalysis, best practice is to use the first morning urine sample of a patient. Stability. The phosphate urine test measures the amount of phosphate in a sample of urine collected over 24 hours (24-hour urine test). 0-1. Ferritin, serum: 15-200 ng/mL They form a clot over damaged blood vessels. The normal range varies with age, and in children it is between 0.85 and 1.0, depending on the serum phosphorus concentration. The transport rate of Na-Pi is substantially higher in brush-border membrane vesicles obtained from neonates than in those from adults. IgM: 20-140 mg/dL A value that isn't in the normal range may still be normal for you. (From Glahn RP, Onsgard MJ, Tyce GM, Chinnow SL, Knox FG, Dousa TP. 0.95 – 1.65 mmol/L. 0.85 – 1.60 mmol/L. Female: 0-20 mm/h Hypophosphatemia is well described in renal transplant patients, although severe hypophosphatemia is rare. Hypophosphatemia with inappropriate urinary phosphate excretion can occur in the absence of hyperparathyroidism, suggesting the presence of non-PTH phosphaturic factors. Storage Transport Temp. Total: 6.0-7.8 g/dL The normal range is just a guide. Phosphate is a charged particle (ion) that contains the mineral phosphorus. Patients also have inappropriately normal serum calcitriol concentrations (Table II). The normal range for TMP/GFR in adults is 2.5–4.2  mg/dL [53,54]; it is higher in children. Normal. Lactate, plasma: 0.5-1.6 mEq/L In contrast, Hyp mice became hypophosphatemic approximately 12 hours after birth.257, In humans, Takaiwat and coworkers studied healthy term infants and compared FGF23 levels in the cord blood with day 5 of life and in healthy adults. Albumin: 3.5-5.5 g/dL ADHR is an autosomal dominant disorder caused by urinary phosphate wasting that has findings commonly seen in other phosphate-wasting disorders. The test id is performed with the help of a … Although Fgf23−/− mice and Klotho−/− mice had normal phosphate homeostasis at birth, they did develop hyperphosphatemia at approximately 1 week of age. Renal proteinuria is persistent and associated with benign or inactive urine sediment (hyaline casts may be observed in the urine sediment in cases of renal proteinuria). Children, Adults. They function as the primary part of the immune response by determining and binding to antigens, such as viruses and bacteria. Doctors will also advise patients to skip drinking, eating, and taking medication several hours before the test. Hypophosphatemia is defined as serum phosphate concentrations lower than the low end of the normal range, whereas a concentration higher than the high end of the range indicates hyperphosphatemia. Nomogram to calculate the TMP/GFR from the TRP [TRP = 1 − (urine phosphorus × serum creatinine)/(serum phosphorus × urine creatinine)] and the concurrent plasma phosphate concentration. Phosphate release from the intracellular stores (mainly bone) is increased by PTH and 1,25(OH)2D3. FIGURE 26.3. Patient results may vary depending on the structure, size, and number of their RBCs. In agreement, proximal Pi reabsorption was reduced in streptotocin-induced diabetes, though without changes of types IIa or III Na/Pi cotransporters mRNAs (43). Factors that increase the excretion of phosphate include PTH, glucocorticoids, calcitonin, glucagon, volume expansion, dopamine administration, and acidosis. Therefore, it is plausible that 1,25(OH)2D3 upregulates FGF-23 production in part indirectly by downregulation of PHEX expression [62–66]. This test is conducted to determine a patient’s heart health through the flow of blood and the amount of oxygen present in the blood. High urine phosphate levels may be caused by: Kidney diseases. The following are the standard normal values for female, male, and child. Prostate-specific antigen, serum: less than 4, Protein, serum This diagnostic examination is important in diagnosing certain illnesses including diabetes mellitus and chronic nephritis. This may reflect homeostatic regulation at a time when phosphate retention is essential for growth. Hypophosptemia is observed in a variety of inherited disorders including X-linked hypophosphatemia, autosomal dominant hypophosphatemic rickets (ADHR), and hereditary hypophosphatemic rickets with hypercalciuria. FGF23 causes urinary phosphate wasting by decreasing the expression of sodium phosphate cotransporters (NaPi-2a and NaPi-2c) on the brush border membrane of the proximal tubule.253 In addition, FGF23 also inhibits the expression of 1α-hydroxylase and increases the expression of 24-hydroxylase,254 resulting in a decrease in circulating levels of 1,25 vitamin D. Klotho is an important coreceptor for FGF23. Volume. In rats treated with streptotocin, the adaptive response to a low-Pi diet on the amount of type IIa Na/Pi cotransporters was blunted indicating that insulin may have a permissive effect on the response of the type IIa Na/Pi cotransporter to changes of the dietary content (63). 24h Creatinine. In addition, vitamin D deficiency leads to hypocalcemia, HPT, and a consequent PTH-mediated increase in renal phosphorus excretion. The 24-hour urine collection is the gold standard method for measuring dietary phosphorus; however, this procedure is cumbersome and prone to timing errors. Aminotransferase, alanine (ALT): 0-35 U/L, Aminotransferase, aspartate (AST): 0-35 U/L, Calcium Phosphate Product (Ca x PO4): 0 – 70. Phosphorus works together with the mineral calcium to build strong bones and teeth. In addition, FGF-23 increases 1 alpha hydroxylase expression in bovine parathyroid cells, which may contribute to reduce PTH gene transcription [36,54,55]. Uric acid is often an indication of kidney stones and a high BUN and creatinine suggest impairment in our kidney. However, confounding factors in the setting of critical illness may contribute to the development of hypophosphatemia in some instances: administration of phosphate-binding antacids, refeeding syndrome, and mechanically induced respiratory alkalosis. 3-5 >0.33 <2.17. 0-1 >0.34 <5.24. Specimen Information Type. Phosphorus absorption occurs primarily in the duodenum and jejunum, and small intestinal malabsorption may lead to hypophosphatemia. The clinical characteristics in oncogenic osteomalacia overlap those in hereditary hypophosphatemic rickets, including hypophosphatemia as a result of renal phosphate wasting, normocalcemia, inappropriately normal 1,25(OH)2D levels for the degree of hypophosphatemia, and skeletal defects caused by osteomalacia. 95th Percentile. In these studies, dopamine induced the internalization of NaPi IIa by activation of luminal DA1 receptors. 1,25(OH)2D stimulates FGF-23 production both in vivo and in vitro. FEPi > 20% (> 0.2 fraction) = high. It is one of the phosphatonins. Adequate phosphate supplementation (13.6 mEq phosphorus per liter of parenteral nutrition) appears to prevent this complication. Participants were followed for a median of 7.4 years for CVD events and all-cause mortality. Lab values are used to determine a patient’s overall health and well-being. During early postnatal life, because of the efficient intestinal absorption and renal retention of phosphate, the neonate is in a positive phosphate balance and presents with elevated plasma concentrations of this anion. Activated clotting time (ACT): 90 to 130 seconds, Activated partial thromboplastin time (APT):  21 to 35 seconds, Partial Thromboplastin Time (PTT):  32 to 45 seconds, Partial Pressure of Oxygen (PaO2): 85 to 100 mm Hg, Partial Pressure of Carbon Dioxide (PaCO2): 35 to 45 mm Hg, Partial Pressure of Oxygen (PaO2): 30 to 40 mm Hg, Partial Pressure of Carbon Dioxide (PaCO2): 41 to 51  mm Hg. Phosphate is a charged particle (ion) that contains the mineral phosphorus. Phosphate should be repleted in patients who are symptomatic, are suspected of having severely depleted intracellular phosphorus stores (malnourished or alcoholic patients), have ongoing gastrointestinal or renal losses, or have severe hypophosphatemia (<1 mg/dL). The normal protein content should be 0- +1 or less than 150mg/day. 6). ... there is variability in serum phosphorus reference ranges between laboratories. Klotho is expressed at the cell surface but is also present in the plasma as two secreted forms. 1,25(OH)2D3 is also able to suppress PHEX mRNA levels in bone cells, and reductions in PHEX can result in increased FGF-23 expression in osteocytes. A low platelet count can mean leukemia or a severe hemorrhage. Jyothsna Gattineni MD, Matthias Tilmann Wolf MD, in Nephrology and Fluid/electrolyte Physiology (Third Edition), 2019. Plasma phosphate concentration is regulated by the kidney. In general, the basic chemistry helps us assess many conditions and give light to how the body’s organs are working. The reduction in the number of Npt2a by FGF-23 seems to be independent of PTH [47]. Using mouse models of FGF23 null mice or FGF23 excess seen in Hyp mice (mouse model of X-linked hypophosphatemic rickets), there was no difference in fetal serum phosphorus, calcium, or PTH levels. Of interest, the expression of Na-Pi mRNA in the newborn is similar to or lower than that in the adult, suggesting that the increased protein levels and activity of this cotransporter early in life may be due to posttranscriptional regulation (Spitzer and Barac-Nieto, 2001). This phenomenon may be due to decreased sensitivity of the proximal tubule to the hormone. FGF-23 also suppresses the 1α-hydroxylase enzyme (CYP27B1) in the renal tubule, the enzyme which stimulates the conversion of 25-hydroxyvitamin D to 1,25(OH)2D. Erythrocyte sedimentation rate Red blood cells or erythrocyte count is measured in millions per cubic millimeter. A value that isn't in the normal range may still be normal for you. A urine phosphate test measures how much phosphate is in your pee over a 24-hour period. Growth hormone stimulates renal phosphate retention and increases the plasma concentration of phosphate. Patients have short stature, bone pain, rickets, and osteomalacia. During weeks 26 to 36 of gestation, the mean intrauterine accumulation of inorganic phosphate is close to 75 mg/kg/day (Wharton et al, 1987). Fasting increases urinary phosphate excretion, which is due to a decrease of tubular reabsorption of Pi. Malnutrition is an uncommon cause of hypophosphatemia. Renal tubule dysfunction, diuretics, and immunosuppressive medication are all contributory factors. It’s also used to check the effectiveness of chemotherapy for patients with cancer. There have been many instances when hypophosphatemia was missed because a low level was mistakenly considered normal because the clinician was not aware of this fact [50]. >0.34. The results of this examination can help doctors diagnose infection and diseases. Erythropoietin: 5-36 mU/mL The proximal tubule reabsorbs approximately 80% of the filtered phosphate load; 10% is reabsorbed by the distal tubule; and 10% is excreted in the urine. Activated partial thromboplastin : 25 to 35 seconds Lipase, serum: 13-60 U/L Increased urine phosphorus excretion is a typical feature of the defect in proximal tubule transport known as Fanconi syndrome. Lab values are used in diagnosis. Laboratory testing involves the checking of blood, urine, and body tissue samples in order to see if the resulting lab values fall within the normal range. David Feldman, Peter J. Malloy, in Encyclopedia of Endocrine Diseases, 2004. Hematology Analyze Immediately at RT (15-25°C) 48 hours refrigerated at 2-8°C. Interpretation of urinary phosphorous excretion is dependent upon the clinical situation, and should be interpreted in conjunction with the serum phosphorous concentration. Collection Instructions. 2.7 – 4.9 mg/dL. Except during menstrual period, there should be no red blood cells present in urine. As most dietary phosphate comes from protein, children in parts of the world where protein malnutrition is common are particularly susceptible to this. This site complies with the HONcode standard for trust- worthy health information: verify here. Your doctor will also look at your results based on your age, health, and other factors. High urine phosphate levels may be caused by: Kidney diseases. Minimum volume: 0.5 mL aliquot from a random urine. A higher or lower number of WBC can indicate an underlying condition such as autoimmune diseases and blood disorders. Numerous studies have demonstrated that acute renal denervation or the administration of catecholamines alters phosphate reabsorption (70, 78, 115, 148–150, 155, 188, 190, 199, 200, 267, 302–304). Reference Range. The hematocrit test is also part of the CBC test and is used to diagnose and monitor several medical conditions. The kidney is the main target organ for FGF-23. A normal range varies between 2.4 to 4.1 mg/dL and could also change depending upon the age. In addition, it is possible that low FGF23 levels also contribute to the higher serum phosphate levels in neonates, which is critical for skeletal mineralization.258. In children and adults, elevated levels of FGF23 cause hypophosphatemic rickets. The normal range varies with age, and in children it is between 0.85 and 1.0, depending on the serum phosphorus concentration. Phosphate is a charged particle (ion) that contains the mineral phosphorus. Among 880 patients with stable CVD and normal kidney function to moderate CKD, 24-hour urine phosphorus excretion (UPE) and serum phosphorus were measured at baseline. 4500 to 11000 per microliter (4.5 to 11.0 × 109/L). Immunoglobulins or antibodies are molecules produced by white blood cells. Cerebral Perfusion Pressure (CPP): 70 to 90 mm Hg, Intracranial Pressure (ICP): 7 to 15 mmHg. High values. False. Hemoglobin tests are performed as part of a complete CBC test. White blood cells in urine indicate an infection in the body. Klotho expression is restricted to a few tissues, including the distal convoluted tubules in the kidney, parathyroid glands, sinoatrial node, pituitary and choroid plexus in the brain. Serum and urine phosphate analysis is usually requested to investigate bone or renal disease. Each laboratory should check if the reference ranges are transferable to its own patient population and determine own reference ranges if necessary. Globulins, total: 2.5-3.5 g/dL, Rheumatoid factor: less than 40 U/mL A line is drawn through the plasma phosphate concentration (the left axis) and TRP (the diagonal axis), and the TMP/GFR value is where that line intersects the TMP/GFR axis (the right axis). In the setting of hypophosphatemia, the normal response of the kidney is to reduce urinary phosphate excretion to less than 100 mg/day or to reduce FEPO4 to less than 5%. If not, measurement of either 24-hour urinary phosphate excretion or fractional excretion of phosphate (FEPO4) in a spot urine sample is often helpful. Phosphorus, 24 hr Urine: 013599: Phosphorus, Urine: mg/dL: 2778-9: 003251: Phosphorus, 24 hr Urine: 013250: Phosphorus,Urine 24h: mg/24 hr: 2779-7 The normal range of phosphorus that should be present in the urine of human body is 68-874 mg/g (males) and 58-846mg/g (female). Excessive FGF23 activity causes phosphaturia and hypophosphatemic rickets. Each bar denotes mean ± SE of four independent experiments, each performed in triplicate. The normal range is just a guide. Oral repletion can be accomplished with sodium or potassium phosphate salts (1 to 2 g/day) or with skimmed milk. Phosphate depletion itself decreases proximal tubular and distal nephron reabsorption of phosphate. Once urinary phosphate wasting is established using such measures, the possibility of other solute losses in the urine should be considered, as generalized renal tubular dysfunction with accompanying phosphate losses may occur in several rare disorders that can lead to Fanconi syndrome, phosphate deficiency, and rickets. PTH is the main physiologic hormone regulating renal phosphate excretion, and it exerts this effect mainly by the inhibition of the Na+-Pi cotransporter in the proximal tubule. 7 FIG. Dopamine infusion and the infusion of L-DOPA or glupopa, dopamine precursors, increase phosphate excretion in the absence of PTH (75, 76, 268). 1-2 >0.34 <3.95. Phosphate renal transport is also modulated by changes in dietary intake. Male: 0-15 mm/h The normal values listed here—called a reference range—are just a guide. Insulin stimulates brush-border Na/Pi cotransport (52, 67). Normal Laboratory Values: Urine Reference values vary based on several factors, including the specific laboratory that supplies them. It is interesting to note that the intact FGF23 was quite low in the cord blood compared with healthy adults. The normal values listed here—called a reference range—are just a guide. The enhanced phosphate reabsorption and attenuated phosphaturic response to PTH observed in acute respiratory alkalosis and phosphate deprivation is blocked by infusion of propranolol, suggesting a possible role for stimulation of β-adrenoreceptors in these conditions. It may still be useful in assessing renal reabsorption of phosphorus in a variety of pathological conditions associated with hypophosphatemia even though direct measurements of PTH have replaced much of the utility of TmP/GFR measurements.
