Bilirubin, Total

The total bilirubin blood test measures the level of bilirubin in your blood. Bilirubin is a yellow pigment that is produced when red blood cells break down. It is processed by the liver and eventually eliminated from the body through bile.

The test is typically performed by taking a blood sample, usually from a vein in your arm, which is then analyzed in a laboratory. Bilirubin levels are reported in milligrams per deciliter (mg/dL) or micromoles per liter (µmol/L).

The total bilirubin blood test is used to assess liver function and to diagnose or monitor conditions related to the liver or red blood cells, such as liver disease, hepatitis, jaundice, or certain types of anemia.

The normal range for total bilirubin levels in adults is generally around 0.3 to 1.9 mg/dL (5 to 32 µmol/L). However, it’s important to note that normal ranges can vary slightly depending on the laboratory and the specific testing method used. Additionally, specific conditions or factors may affect bilirubin levels, so interpretation of the test results should be done in consultation with a healthcare professional.

If your total bilirubin levels are outside the normal range, further evaluation may be needed to determine the underlying cause. Treatment will depend on the specific condition or disease that is affecting bilirubin levels.

It’s important to follow your healthcare professional’s guidance regarding total bilirubin levels and any necessary treatment, as abnormal bilirubin levels can be indicative of liver or blood-related disorders.
