The Purpose of a Direct Bilirubin Test

The liver is one of the undersung organs in your body. It may not get as much attention as the heart or brain, but it plays more than 500 roles in maintaining optimal health. That’s why you need to take care of your liver and pay attention if you notice troubling symptoms such as jaundice and fatigue. These could be signs you need to check on your bilirubin levels.

What Does the Bilirubin Direct Blood Test Measure?

Bilirubin is a by-product of red blood cells. It’s typically processed through the liver before being eliminated from the body. If your blood test for direct bilirubin comes back with abnormal levels, it means your liver isn’t working as it should and could be a sign of:

  • Liver or gallbladder disease
  • Hepatitis
  • Anemia

If you have one of these conditions, a blood test for bilirubin direct may gather data on the progress of your treatment.

Who Should Take a Direct Bilirubin Blood Test for Ferritin?

Testing may be advised if you have a gallbladder or liver condition, or if you are exhibiting symptoms such as jaundice.

Bilirubin Direct Blood Test Preparation

No special preparation is typically required for the blood draw, but you may want to confirm if the lab has any instructions you need to follow.

Direct Bilirubin Results

A blood test for direct bilirubin should come back measuring less than 0.3 mg/dL. (It may also be listed as conjugated bilirubin.) Some tests may also provide your total bilirubin levels, which include a reading of your indirect bilirubin that attaches to the albumin in your blood. Normal total bilirubin ranges from 0.1 to 1.2 mg/dL. Depending on the results, you may need more liver function tests. If you need assistance determining what testing is best for you, set up a telehealth visit with a Personalabs board-certified physician who can tell you what your results mean.
