Limitations. With reduced renal blood flow, creatinine rises less quickly than urea nitrogen. Concentration of creatinine only becomes abnormal when about half or more of the nephrons have stopped functioning in chronic progressive renal disease. Antibiotics containing cephalosporin lead to significant false-positive values if samples are drawn ...Use. A liver function test, ALT is more sensitive for the detection of hepatocyte injury than for biliary obstruction. ALT is more specific for liver injury than AST (SGOT).

The intended use of the urinary orotic acid test is to identify elevations of orotic acid in patients with folate malabsorption or hereditary orotic aciduria (uridine-5'- monophosphate synthase deficiency), and to aid in the differential diagnosis of hyperammonemia and urea cycle defects. Elevated excretion of orotic acid also has been ...They can be granular or waxy. Broad waxy casts are called "renal failure casts.". Sperm is not reported in routine urinalysis exams. Spermatozoa may be seen in male urine related to recent or retrograde ejaculation. For sperm reporting in males only, order Postejaculatory Urine Microscopic Examination for Sperm [133116].This assay is intended for the in vitro quantitative determination of carcinoembryonic antigen in human serum and plasma. 1 The Elecsys CEA assay is further indicated for serial measurement of CEA to aid in the management of cancer patients. The main indication for CEA determinations is the follow-up and therapy-management of colorectal carcinoma.

Use. Presence of antibody to hepatitis B surface antigen (anti-HBs) is used to determine immune status to HBV or disease progression in individuals infected with HBV. Anti-HBs levels can be measured to determine if vaccination is needed, or following a vaccination regimen, to determine if protective immunity has been achieved.To the Editor. — Accurate measurement of blood ammonia is useful in diagnosing inherited disorders of urea metabolism and Reye syndrome and in the differential diagnosis of encephalopathy.1 The most commonly used method in clinical labs is an enzymatic kinetic assay in which ammonia reacts with α-ketoglutarate and nicotinamide adenine dinucleotide phosphate (reduced form; NADPH) to form ...Some methods have shown the direct bilirubin to be spuriously high. This may be due to different concentrations of sodium nitrite, which may convert some of the unconjugated bilirubin to conjugated bilirubin. 1,2 Direct bilirubin is the water soluble fraction. When increased in serum, bilirubin should become positive in the urine.

Total iron binding capacity <240 μg/dL 1 and/or low transferrin levels would support an impression of inadequate protein reserves.
