The Dihydrotestosterone (DHT) test is performed to measure the level of Dihydrotestosterone (DHT) in the blood. DHT is a potent androgen hormone, metabolized from testosterone by the action of the enzyme 5-alpha reductase. DHT plays an important role in the development of male sexual characteristics and affects various physiological functions in the body.

An ADAMTS13 activity assay test measures the level of activity of the ADAMTS13 enzyme in a blood sample, which is crucial for regulating the size of von Willebrand factor (VWF) multimers and preventing excessive blood clotting; a low ADAMTS13 activity level is strongly associated with the diagnosis of thrombotic thrombocytopenic purpura (TTP). 

. C-peptide is a protein fragment released in equal amounts with insulin when proinsulin is cleaved.
. C-Peptide is useful in the evaluation of pancreatic beta cell function (e.g., helping distinguish type 1 from type 2 diabetes mellitus, or monitoring patients who have received islet cell or pancreatic transplants) and for determining the source of insulin in patients with hyperinsulinemic hypoglycemia (e.g., distinguishing insulin-secreting tumors from exogenous insulin administration).

Refers to a laboratory test that uses a technique called isoelectric focusing to analyze both cerebrospinal fluid (CSF) and serum samples to detect the presence of “oligoclonal IgG bands,” which are specific patterns of immunoglobulin G (IgG) proteins that can indicate an immune response occurring within the central nervous system (CNS), often associated with diseases like multiple sclerosis (MS).
