What does reactive hepatitis A and B mean?

Hepatitis panels can measure different antibodies and antigens. Some markers suggest past exposure or vaccination, while others can indicate a current or recent infection. A report that says reactive without naming the marker is incomplete for interpretation. Hepatitis A and hepatitis B are separate infections, so one reactive result does not explain the other.

Symptoms such as nausea, loss of appetite, dark urine, or feeling generally unwell may occur with hepatitis, but they can also have many other causes. The result must be read alongside your history, examination, and other tests.

Keep the complete laboratory report and arrange a review with the clinician who ordered it. Ask which marker was reactive, whether a repeat or confirmatory test is needed, and whether liver enzymes should be checked with a liver function test. Until the result is explained, avoid donating blood and ask about precautions involving sex, needles, or sharing personal items. Do not assume that a reactive result means you need treatment immediately.

Get prompt medical advice for yellow skin or eyes, dark urine, persistent vomiting, worsening abdominal pain, or marked weakness. Seek urgent care for confusion, fainting, bleeding, severe dehydration, or difficulty staying awake. Pregnancy, immune suppression, or known liver disease should lower the threshold for contacting your care team.

Ask which hepatitis marker was tested, whether it reflects immunity, past exposure, or possible current infection, and what follow-up testing is needed. Clarify whether close contacts require testing or vaccination and whether medicines or alcohol should be avoided while the result is reviewed.
