A complete blood count (CBC) test can help identify underlying conditions that may cause jaundice, but it does not directly detect jaundice itself. Jaundice is a yellowing of the skin and whites of the eyes caused by a buildup of bilirubin in the blood. While a CBC test measures red blood cells, white blood cells, and platelets, it does not assess bilirubin levels.
To diagnose jaundice, a bilirubin blood test is necessary. This test measures the amount of bilirubin in the blood, which can indicate the presence of liver, bile duct, or other health problems.
A CBC test can be useful in detecting hemolysis, a condition where red blood cells are destroyed prematurely, which can lead to jaundice. Hemolysis can be indicated by low red blood cell counts and high bilirubin levels in the blood.
In addition to a CBC test, other tests that may be used to diagnose jaundice include:
- Liver function tests: These tests assess the health of the liver and can help identify potential causes of jaundice.
- Urinalysis: This test can help determine if bilirubin is present in the urine, which can also be a sign of jaundice.
- Imaging tests: These tests, such as an ultrasound or CT scan, can help visualize the liver and bile ducts to identify any abnormalities that may be causing jaundice.
Therefore, while a CBC test cannot directly detect jaundice, it can provide information that helps identify potential causes of this condition.
