Short Name: AcetylSample required: SerumResult Time: 3 Days Acetylcholine receptor antibodies are implicated in the loss of functional receptors in the post-synaptic membrane that underlies the defect in neuromuscular transmission in Myasthenia gravis. Myasthenia gravis is an acquired disorder of neuromuscular transmission characterized by muscle weakness and fatigability. Serial measurements of AChR antibodies can be
Read moreShort Name: ACESample required: SerumResult Time: 1 Days Angiotensin converting enzyme (ACE) is a catalytic glycoprotein, which cleaves angiotensin I to generete the active form of the hormone, angiotensin II. It is produced by endothelial cells to help regulate blood pressure, acting as a vasoconstricting agent. This test is of diagnostic and prognostic use in
Read moreShort Name: ANDSample required: SerumResult Time: 1 Days Androstenedione is a 19-carbon steroid hormone produced in the adrenal glands and the gonads as an intermediate step in the biochemical pathway that produces testosterone, estrogens and estradiol. Androstenedione is useful in investigating the cause of high testosterone levels in women, and in management of patients with
Read moreShort Name: aaSample required: SerumResult Time: 21 Days Beta-Amyloid is a peptide of 39-43 amino acids that is derived from Amyloid Precursor Protein (APP). In a healthy brain, beta-amyloid is broken down and eliminated, while in Alzheimers disease (AD), the fragments accumulate to form hard, insoluble plaques (senile plaques). This test plays a role in
Read moreShort Name: AMYSample required: SerumResult Time: 1 Days Amylase is a polysaccharide-hydrolyzing enzyme secreted in the pancreas and salivary glands. This test is sometimes used to monitor treatment of some cancers involving the pancreas and after removal of gallstones that have caused gallbladder attacks. HIGH levels are found in acute hemorrhagic pancreatitis, chronic pancreatitis, mumps,
Read moreShort Name: AMY 24Sample required: UrineResult Time: 1 Days The ?-amylases (1,4-?-D-glucanohydrolases, EC 3.2.1.1) catalyze the hydrolytic degradation of polymeric carbohydrates such as amylose, amylopectin and glycogen by cleaving 1,4-?-glucosidic bonds. In polysaccharides and oligosaccharides, several glycosidic bonds are hydrolyzed simultaneously. Maltotriose, the smallest such unit, is converted into maltose and glucose, albeit very slowly.

Read moreShort Name: AMOSample required: EDTA PlasmaResult Time: 1 Days Most of the ammonia formed in the body is due to the breakdown of proteins by urea-splitting bacteria in the intestinal tract. The liver converts ammonia produced into urea, which is then eliminated in urine. The concentration of ammonia in the plasma is low as long
Read moreShort Name: A2MSample required: SerumResult Time: 14 Days Alpha-2-Macroglobulin is a glycoprotein synthesized in the liver and is a major component of the alpha-2 band in protein electrophoresis. It is able to inactivate an enormous variety of proteinases, and also functions as an inhibitor of coagulation by inhibiting thrombin, and inhibitor of fibrinolysis by inhibiting
