If your Bilirubin indirect is in between 0.1 mg/dL and 1 mg/dL, then you need not worry as 0.1-1 mg/dL is the normal range for Bilirubin indirect. But if your Bilirubin indirect is lesser or greater than the above values, then there may be some problem in your body.
What causes increased direct bilirubin?
The conjugated (direct) bilirubin level is often elevated by alcohol, infectious hepatitis, drug reactions, and autoimmune disorders. Posthepatic disorders also can cause conjugated hyperbilirubinemia.
What does bilirubin direct mean?

Bilirubin is a yellow compound produced during the normal breakdown of hemoglobin, the compound in red blood cells that allows them to carry oxygen. As red blood cells are broken down, the iron -containing part of hemoglobin (heme) is converted to bilirubin [ 1 ].
How to calculate indirect bilirubin?
Indirect bilirubin is calculated from direct and total figures, where indirect = total minus direct bilirubin. As such, the normal range given for indirect bilirubin is generally the same or very slightly lower than for total bilirubin.
Why do you need bilirubin test?
Bilirubin tests are usually ordered to monitor liver health. Indirect bilirubin is the unconjugated form of bilirubin in the blood. It is carried from the blood to the liver where it is conjugated to its direct form and excreted into the intestines. Indirect and direct bilirubin together make up total bilirubin. Indirect bilirubin may be too high when the liver is unable to adequately process (conjugated) bilirubin or when there is abnormal destruction of red blood cells (hemolysis). Meanwhile, direct bilirubin may be too high if the liver is unable to pass on the bilirubin after it has been conjugated.
What enzyme converts bilirubin into bilirubin?
The UGT1A1 enzyme, which converts indirect bilirubin into direct bilirubin, is well-developed in the adult liver, but not in the livers of newborns. This is why jaundice with high indirect bilirubin is common in babies [ 2 ].

What is bilirubin bound to?
Bilirubin that is bound to a certain protein is called unconjugated, or indirect, bilirubin. Conjugated, or direct, bilirubin travels freely through your bloodstream to your liver. Most of this bilirubin passes into the small intestine. A very small amount passes into your kidneys and is excreted in your urine. This bilirubin also gives urine its distinctive yellow color.
What causes bilirubin to rise?

What is the process of bilirubin being released into the intestine?
Indirect bilirubin is formed by the breakdown of hemoglobin in the red blood cells. The liver converts this bilirubin into direct bilirubin, which can then be released into the intestine by the gallbladder for elimination. Total bilirubin levels are therefore indicative of both the destruction of red blood cells and the proper functioning of the liver, gallbladder, and bile ducts.
