Question
Does a child need to eat before having blood tests for hepatitis B antibodies?
Answer
Hello, you’re inquiring about dietary considerations before a blood test. The Hepatitis B antibody test involves a Hepatitis B panel, which can be done either fasting or after eating without affecting the results. Guidance: If a liver function test is also required, it must be done fasting. This is because certain components in the blood can change after eating, potentially affecting the accuracy of the liver function panel.
