Confirmatory testing for hepatitis A

A clinician may ask about fatigue, nausea, appetite changes, abdominal discomfort, dark urine, yellowing, recent travel, food or water exposure, and contact with someone who has hepatitis A. The examination may look for jaundice, dehydration, abdominal tenderness, or other signs of illness. Blood tests can look for markers of recent hepatitis A infection and can measure liver inflammation or injury.

A Liver Function Test provides information about how the liver is responding, but it does not by itself identify hepatitis A. Results need to be read in context, and a clinician may repeat or add tests if the timing of exposure or symptoms makes the first result difficult to interpret.

Tell the clinician when symptoms began, whether anyone close to you has been diagnosed, and every medicine, supplement, or recreational substance you use. Drink fluids if you can, rest, avoid alcohol, and do not start or stop medicines without advice. Follow instructions about blood sampling and food preparation while results are pending, because possible hepatitis A can be transmissible.

Seek urgent help for confusion, unusual drowsiness, repeated vomiting, inability to drink, severe abdominal pain, bleeding, or quickly worsening yellowing. Arrange prompt testing after a significant exposure or when dark urine and marked fatigue occur, even if jaundice is absent.

Ask which blood tests are being ordered, what each result can show, whether timing affects interpretation, when results are expected, whether repeat testing is needed, and how to reduce spread while waiting.
