Total Bilirubin Screening Test - Total Bilirubin Test

A measurement of the total bilirubin level in the blood, which is the sum of direct (conjugated) and indirect (unconjugated) bilirubin. It is a vital indicator of the balance between bilirubin production from the breakdown of red blood cells and the liver's ability to receive, conjugate, and excrete it. Any disruption in this chain leads to elevated bilirubin levels and the appearance of jaundice.
