Bilirubin Total and Direct Blood Test

What is the purpose of this test?

The Bilirubin Total and Direct Blood Test measures the levels of bilirubin in your blood to help assess liver function and detect potential liver or blood-related conditions. Bilirubin is a yellow substance that forms when red blood cells break down. The liver processes bilirubin and helps remove it from your body. High bilirubin levels may indicate liver problems, bile duct blockages, or increased red blood cell breakdown, leading to jaundice (yellowing of the skin or eyes).

This test measures two types of bilirubin: total bilirubin and direct (conjugated) bilirubin. Total bilirubin is the overall amount of bilirubin in your blood, while direct bilirubin measures the portion that has been processed by your liver. By comparing these levels, your healthcare provider can gain important insights into how well your liver is functioning and identify potential health issues, such as liver disease, gallbladder problems, or hemolytic anemia (a condition where red blood cells break down too quickly).

Who should get this test?

• Individuals with symptoms of jaundice, such as yellowing of the skin or eyes.
• Those with a family history of liver disease or gallbladder problems.
• Individuals experiencing unexplained fatigue, nausea, or abdominal pain.
• People undergoing treatment that may affect liver function.
• Individuals with a history of alcohol or drug use that could impact liver health.
• Those who have had abnormal liver function tests in the past.

When should I order the Bilirubin Total and Direct Blood Test?

Individuals may consider ordering this test if they have symptoms or exposure concerns related to bilirubin levels. Symptoms to consider:

• Yellowing of the skin or eyes (jaundice).
• Dark-colored urine or pale-colored stools.
• Nausea, vomiting, or unexplained weight loss.
• Fatigue or weakness.
• Abdominal pain or swelling.
• Itchy skin without a clear cause.

If you have these symptoms or suspect a liver or blood-related condition, the Bilirubin Total and Direct Blood Test can provide useful information to guide you and your doctor in managing your health.
