A wide range of disease entities alters AST (SGOT), with origin from many organs. When an increased AST is from the liver, it is more likely to relate to disease of the hepatocyte. Other enzymes, including alkaline phosphatase and GT, are more sensitive indicators of biliary obstruction. Causes of low AST: uremia, vitamin B 6 deficiency (this ...C-peptide is a single chain 31-amino acid (AA 33-63) connecting (C) polypeptide with a molecular weight of approximately 3021 daltons. 2,3 In the process of biosynthesis of insulin, the C-peptide is formed as a byproduct together with insulin by the proteolytic cleavage of the precursor molecule proinsulin, stored in secretory granules in the ...Container. Vacutainer® gray-top urine culture transport tube with preservative (preferred). If less than 4 mL of urine is collected, usually from pediatric and geriatric patients or from a catheter, submit refrigerated in a sterile, screw cap container or tube. Do not submit low volume urine specimens in underfilled gray top tubes.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.
