Laboratory Testing for Hepatitis A and E

Patient Case

September 2008

Back to our patient study, using tests available at Mayo Medical Laboratory, there are two options for testing this individual’s immune status to Hepatitis A vaccination. One can order either the Hepatitis A total antibodies test or the Hepatitis A total antibodies with reflex to IgM antibodies test.

In this individual, the provider requested the Hepatitis A total antibodies only and the results came back positive.
