Bilirubin Test

The Bilirubin Test is a blood test that measures the levels of bilirubin, a yellow pigment produced during the breakdown of red blood cells.

• It is commonly used to evaluate liver function and diagnose conditions such as jaundice, liver disease, or other disorders affecting the liver or bile ducts.
• Bilirubin levels can help identify the cause of the yellowing of the skin and eyes (jaundice) and monitor the effectiveness of treatment.

The Bilirubin Test typically involves a blood sample collected through a venipuncture, usually from a vein in the arm.

• The blood sample is then analyzed in a laboratory using specialized techniques to measure the levels of total bilirubin and, in some cases, direct and indirect bilirubin.
• Preparation for the test may involve fasting for a certain period before the blood draw, as instructed by the healthcare provider.

Elevated bilirubin levels can indicate liver dysfunction, such as hepatitis, cirrhosis, or other liver diseases.

• Higher levels of bilirubin may also suggest an obstruction in the bile ducts, such as gallstones or tumors.
• Low levels of bilirubin are generally considered normal. However, interpretation of results should be done in conjunction with other clinical information to determine the underlying cause and appropriate treatment plan.

The normal range for total Bilirubin in adults typically falls between 0.3 and 1.2 milligrams per deciliter (mg/dL) or 5.1 and 20.5 micromoles per liter (µmol/L). However, the specific reference range may vary slightly depending on the laboratory. It is important to note that the interpretation of Bilirubin levels should consider the clinical context, and healthcare professionals are best suited to assess the significance of the results based on individual circumstances.
