Bilirubin: What You Need To Know
Bilirubin Test Overview and Purpose
The bilirubin test is a laboratory procedure that measures the levels of bilirubin in the blood. Bilirubin is a yellow pigment produced during the normal breakdown of red blood cells.
This test serves several purposes, including evaluating liver health. Elevated levels of bilirubin may indicate liver or bile duct issues, such as hepatitis or gallstones. Additionally, the test is useful for diagnosing conditions associated with abnormal breakdown of red blood cells, including anemia. In newborns, the test is utilized to detect jaundice, a condition characterized by yellowing skin and eyes.
The bilirubin test is not only significant for assessing liver function but also plays a crucial role in diagnosing various conditions.
Procedure and Accompanying Tests for Bilirubin
Testing bilirubin levels involves a simple blood test. Bilirubin is a yellow substance the body creates when it replaces old red blood cells. It's part of what makes bruises yellow as they heal and gives urine its color.
The procedure involves drawing a small amount of blood from the arm for analysis in a lab.
Two types of bilirubin are tested:
- Direct bilirubin dissolves in water (it's soluble) and high levels may indicate liver or bile duct problems.
- Indirect bilirubin, not soluble in water, can suggest issues such as anemia if the levels are elevated above the normal range.
Accompanying tests may include:
- Liver function tests
- A complete blood count (CBC)
Liver function tests assess the liver's performance, while CBC counts different cells in the blood, including red ones.
In conclusion, testing for bilirubin is straightforward and provides important information about potential health conditions.

Interpreting Bilirubin Test Results and Understanding Levels
A bilirubin test measures the amount of bilirubin in the blood. Bilirubin is a yellow substance produced when the body breaks down red blood cells. Normal levels vary, but for adults, bilirubin levels are typically less than 1.2 milligrams per deciliter (mg/dL). Levels exceeding this threshold may indicate a health issue.
There are two types of bilirubin: direct and indirect.
- Direct bilirubin is water-soluble, whereas indirect bilirubin is not.
- Elevated levels of direct bilirubin can be indicative of liver problems, such as hepatitis or a bile duct blockage.
- Conversely, high levels of indirect bilirubin may suggest issues related to the rapid breakdown of red blood cells.
The interpretation of results takes into account factors such as age and health status, with particular consideration for newborns who often experience temporary elevated bilirubin levels, leading to jaundice. Adults presenting with persistent high values may be experiencing underlying conditions such as gallstones or tumors obstructing the bile ducts.
Understanding what constitutes a normal range involves considering multiple factors, including age and overall health condition.
Gilbert's Syndrome and Monitoring Conditions with Bilirubin Test
Gilbert's Syndrome is a genetic disorder that affects the liver's ability to process bilirubin, a yellowish substance in the blood. Individuals with Gilbert's syndrome may experience a build-up of bilirubin, potentially leading to mild jaundice, which manifests as slight yellowing of the eyes and skin.
A Bilirubin Test is used to monitor this condition by measuring the amount of bilirubin in the blood. Elevated levels of bilirubin may indicate Gilbert’s Syndrome or other liver-related conditions.
The procedure for obtaining a sample for a Bilirubin Test involves:
- Drawing a small volume of blood from a vein in the arm using a needle and syringe, or
- A finger prick for infants.
Regular monitoring with Bilirubin Tests is beneficial for individuals with Gilbert's Syndrome to manage their condition. Symptoms associated with high bilirubin levels include fatigue, abdominal pain, and jaundice.
Information is a valuable tool in health management.
