Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
A blood sample taken from an arm vein.
Test Time:
The test results are typically available within a few hours to a day.
Test Normal Range:
Total Bilirubin: 0.2 – 1.2 mg/dL (milligrams per deciliter)
Direct Bilirubin: 0.0 – 0.3 mg/dL
Indirect Bilirubin: 0.2 – 1.0 mg/dL
What is the Test?
The Bilirubin Test measures the levels of total bilirubin, direct bilirubin, and indirect bilirubin in the blood. Bilirubin is a yellow pigment produced by the breakdown of haemoglobin in red blood cells. It is broken down in the liver and eliminated in the bile.
Test Procedure:
A healthcare professional will clean the area around a vein in your arm. A needle is inserted into the vein, and a blood sample is collected into a vial or syringe. The blood sample is sent to a laboratory for analysis. Laboratory technicians measure the levels of total, direct, and indirect bilirubin in the blood sample.
When to Take the Test:
This test may be ordered if there are concerns about liver function, jaundice, or if a person is showing symptoms of liver disease, such as yellowing of the skin and eyes, dark urine, and pale stools.
Who Should Take This Test:
Individuals with suspected liver disease, gallbladder issues, or those showing symptoms of jaundice may be advised to take this test.
Precautions for Exceptional Cases (Pregnancy etc.):
If you are pregnant, breastfeeding, or have any existing medical conditions, inform your healthcare provider before taking this test. Pregnancy and certain medical conditions can affect bilirubin levels.
FAQs:
Q1: What do elevated bilirubin levels indicate?
A: Elevated total bilirubin levels can indicate liver disease, hemolytic anemia, or blockage of bile flow. Elevated direct bilirubin levels may suggest issues with the bile ducts or liver. Elevated indirect bilirubin levels may indicate excessive breakdown of red blood cells.
Q2: Can certain foods affect bilirubin levels?
A: While diet can impact bilirubin levels to some extent, it is important to consult a healthcare provider for accurate interpretation of test results.
Q3: Can medications affect bilirubin levels?
A: Yes, certain medications can impact bilirubin levels. Any medications you are taking should be disclosed to your healthcare professional.
Q4: Can newborns have high bilirubin levels?
A: Yes, newborns can have high bilirubin levels due to their immature liver function. This condition is called jaundice and is monitored and managed by healthcare providers.
Q5: Is fasting required before the test?
A: Usually, this test doesn’t demand you to fast. However, your healthcare provider will provide specific instructions.
