What should you know about a hepatitis C home test?

Many home kits use a small finger-prick blood sample to look for antibodies. Antibodies show that your immune system has encountered hepatitis C at some point; they do not by themselves prove that the virus is still present. A negative result may be reassuring, but recent exposure or an incorrectly collected sample can affect interpretation. Hepatitis C can have no obvious symptoms, although some people develop fatigue or other changes in health.

Follow the kit instructions carefully, including the timing for reading the result and the process for sending a sample if the test uses laboratory processing. Do not treat a home result as a diagnosis. Arrange a GP Consultation if the result is positive, unclear, or difficult to collect. A clinician may arrange a laboratory test that checks for current infection and may also review liver health, including a Liver Function Test.

Contact a healthcare professional promptly after a positive or uncertain result so that follow-up is not missed. Seek urgent medical help for yellowing of the skin or eyes, severe abdominal pain, vomiting blood, black stools, marked confusion, or extreme drowsiness. These symptoms can have several causes and need assessment rather than interpretation at home.

Ask which confirmatory test you need, whether the timing of a possible exposure changes the testing plan, and whether your medicines or liver health need review. You can also ask how to protect others while results are being clarified.
