Total Bilirubin
Evaluates total bilirubin levels.
About this test
Total bilirubin measures the combined amount of bilirubin circulating in blood.
Common reasons for testing
- Investigation of jaundice or monitoring a known bilirubin abnormality.
These are examples of clinical uses. Your history and symptoms determine whether testing is appropriate.
What to expect
A small blood sample is taken from a vein in your arm. You may feel a brief pinch and have mild bruising. Tell the person collecting your sample if you have fainted with needles or take a blood thinner; keep pressure on the site afterward.
Appointment length
Your visit is expected to take about 15 minutes at our West Ashley location.

Preparation
- Avoid unrequested prolonged fasting; it can affect bilirubin in some people. Follow instructions if another ordered test requires fasting.
- Bring a list of medicines and supplements, including biotin, vitamins, and hormones. Do not stop or change prescribed medicines unless your clinician tells you to.
Order requirement
No outside order needed
Understanding your results
- An elevated total may need direct and indirect fractions to help determine the cause.
What happens next?
Review the report with your clinician alongside your symptoms, medical history, and earlier results. A value outside the reference range does not always mean disease, and a normal result does not explain every symptom. Confirm who will arrange any repeat or additional testing.
