Bilirubin is in the insoluble form, unconjugated bilirubin (indirect bilirubin).The non-water soluble, free bilirubin does not react with sulfanilic acid at acidic pH to produce a red colored complex until an accelearator, alcohol, is added to the solution to perform a quantitative measurement of unconjugated bilirubin levels.

Indicadores
A synthetic form of dehydroepiandrosterone with potential chemopreventive activity. Produced endogenously, dehydroepiandrosterone (DHEA) is an intermediate in the conversion of cholesterol to androgens and estrogens. Although the mechanisms of action of exogenously administered DHEA have not been fully illuminated, they may result in both direct and indirect physiologic effects. Direct effects include GABA-a receptor complex and NMDA receptor modulation, and enhanced pancreatic beta cell insulin secretion and antiglucocorticoid activities. (NCI04)
Pruebas
