The LEVRAM Bilirubin Reagent Kit is designed for the quantitative determination of both direct and total bilirubin in human serum or plasma. It utilizes the diazo method, where bilirubin reacts with diazotized sulfanilic acid to form a colored compound, the intensity of which is measured photometrically. This kit is commonly used in liver function tests, jaundice screening, and monitoring hepatic disorders.
