Patient's question:
The child needs to have blood drawn for a test to check for hepatitis B antibodies. Should they eat anything before having their blood drawn?Doctor's answer:
Hello, you are inquiring about the dietary requirements for blood tests. For the hepatitis B antibody test, it is necessary to undergo the five-item hepatitis B test. This test can be performed both on an empty stomach and after eating, and it does not affect the results.Advice: If you also need to have liver function tests, you should fast. This is because some components in the blood may change after eating, which could affect the accuracy of liver function test results.
