Understanding Lab Tests for Gilbert's Syndrome
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Gilbert's Syndrome is a common, benign genetic condition affecting how the liver processes bilirubin, a yellow compound produced when red blood cells break down. While generally harmless, it can cause mild jaundice and is diagnosed through specific blood tests that measure bilirubin levels.
Top Recommended Test
Bilirubin, Total
This test measures the total amount of bilirubin in the blood and is essential for diagnosing Gilbert's Syndrome. People with this benign liver condition typically show mildly elevated total bilirubin levels due to the liver's reduced ability to process this compound effectively.

How Gilbert's Syndrome is Diagnosed
Gilbert's Syndrome is primarily diagnosed through blood tests that reveal a characteristic pattern of elevated bilirubin levels. The condition typically shows increased total and indirect bilirubin while direct bilirubin remains normal, which helps distinguish it from other liver conditions.
Other Relevant Tests
Bilirubin, Direct
This test measures direct (conjugated) bilirubin levels and is important for confirming Gilbert's Syndrome diagnosis. In this condition, direct bilirubin levels typically remain normal, which helps differentiate it from other liver disorders that might cause elevated total bilirubin.

Liver Function Profile
This comprehensive panel includes indirect bilirubin measurement along with other liver enzymes. Abnormally high levels of indirect bilirubin within this profile can indicate Gilbert's Syndrome, while other liver function markers typically remain normal in this benign inherited condition.

Understanding Your Results
In Gilbert's Syndrome, you'll typically see elevated total bilirubin (primarily the indirect form) while direct bilirubin and other liver enzymes remain normal. This specific pattern helps healthcare providers distinguish Gilbert's Syndrome from more serious liver conditions and provides reassurance about the benign nature of the condition.
