After completing this article, readers should be able to:. Describe the metabolism of bilirubin. Evaluate a child of any age who has conjugated hyperbilirubinemia. Having a blood test with a needle carries some risks.

These include bleeding, infection, bruising, and feeling lightheaded. When the needle pricks your arm or hand, you may feel a slight sting or pain. Afterward, the site may be sore. Strenuous exercise and pregnancy can affect your results. Vitamin C, androgen hormones, and certain medicines, such as phenazopyridine and rifampin, can affect your results. You don't need to prepare for this test.

Tell your healthcare provider about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any illegal drugs you may use. Search Encyclopedia. Direct Bilirubin Does this test have other names? Conjugated bilirubin What is this test? This test looks for bilirubin in your blood or urine. Why do I need this test? Signs and symptoms include: Yellowing of your skin and whites of your eyes jaundice Dark yellow-colored urine Light gray or clay-colored stools Nausea Vomiting Severe tiredness fatigue Belly pain or swelling You may also have this test to check for possible liver damage if you drink a lot of alcohol on a regular basis.
