Bilirubin is the yellow pigment left over when old red blood cells are broken down. A mildly raised result is common and often harmless, but the pattern matters.
Total Bilirubin. All the bilirubin in the blood, the starting point for seeing whether levels are raised.
Direct and Indirect Bilirubin. Indirect bilirubin has not yet been processed by the liver, while direct bilirubin has, so the split shows where in the process a rise is happening.
Red blood cells last about four months. When they are broken down, the body makes bilirubin, which the liver processes and clears into bile. If more is made than usual, or the liver cannot process or clear it, bilirubin builds up in the blood. At high levels it causes yellowing of the skin and eyes, called jaundice.
The most common reason for a mildly raised bilirubin is Gilbert's syndrome, a common inherited pattern in which the liver processes bilirubin a little more slowly. It is harmless and often first noticed on a routine blood test. It typically shows as a raised indirect bilirubin with normal liver enzymes, and it can rise after fasting, illness, poor sleep or hard exercise. A raised direct bilirubin is less common and is more likely to reflect a liver or bile flow problem.
UAE labs usually report bilirubin in micromoles per litre (umol/L), and some use mg/dL. Many labs put the upper limit of total bilirubin at around 17-21 umol/L, but reference ranges vary by lab.
A mildly raised indirect bilirubin with normal liver enzymes is often Gilbert's syndrome. Indirect bilirubin can also rise when red blood cells break down faster, which the blood count on the same screen helps check. A raised direct bilirubin, or a high result with raised ALP or GGT, needs follow-up with your own doctor.
A low bilirubin is not usually a concern and does not need any action on its own.
Reference ranges differ between labs, and a single result is a snapshot. Your consultant reads every value against your history and the rest of the screen, not in isolation.
This test is part of Baseline’s full blood screen: 122 parameters across ten systems from one draw, for AED 850, with results in 48 hours. It is not sold as a single test, because the result means more next to everything else.
Ranges are the lab’s own. Your consultant goes through what they mean with you.
Your results arrive in the Baseline app, every marker against the lab’s own range, checked by your consultant before you see them. The values above are an example.

Reading is not a diagnosis. A consultation goes through your history with you and tells you plainly whether a program fits, including when it does not. AED 350, credited in full against your first order.
