Direct Bilirubin

There are two major proteins in the blood. Albumin helps keep blood from leaking out of blood vessels and moves other important substances throughout the body, while globulins help fight infection and move nutrients throughout the body. The A/G ratio compares the amount of albumin in your blood to the amount of globulin. This test helps diagnose kidney disease, liver disease, or nutritional problems.

Total Bilirubin level test is a blood test that measures all the bilirubin in the blood. Bilirubin is the stuff made when the body breaks down old red blood cells, and usually, the liver processes it so the body can get rid of it. This test combines the counts of both direct bilirubin (the type the liver has processed and is ready to be eliminated) and indirect bilirubin (the kind that hasn’t been processed by the liver yet). It’s a good way to check on the liver’s health and see if everything’s working right, from breaking down cells to removing waste. High total bilirubin could hint at liver issues or other problems with how the body deals with blood cell breakdown.
