What should you know about hepatitis C saliva?

Hepatitis C is mainly associated with infected blood entering another person’s bloodstream. Everyday contact such as sharing food, kissing, or using the same cups does not usually spread it. Saliva can be contaminated with blood when gums are bleeding or the mouth is injured, so blood exposure deserves medical advice. A saliva-based screening method, if offered in a particular setting, still needs clear interpretation and may require confirmatory blood testing. A positive antibody finding does not by itself prove that virus is currently present.

If you are worried after contact with blood, describe exactly what happened, when it happened, and whether skin or mucous membranes were broken. Do not share toothbrushes, razors, needles, or manicure tools that may carry blood. Arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) to discuss the right test. Information about [Hepatitis C](/conditions/hepatitis-c/) can help you prepare, while a [Liver Function Test](/treatments/diagnostics-and-screening/liver-function-test/) may form part of a broader assessment.

Seek prompt advice after a fresh blood exposure involving the eyes, mouth, broken skin, or a puncture wound. Contact a clinician urgently if you develop yellow skin or eyes, dark urine, unusual drowsiness, repeated vomiting, or severe abdominal pain. Tiredness is worth mentioning even when it is mild; see [Fatigue](/symptoms/fatigue/) for context.

Ask whether the exposure needs testing, which sample is appropriate, when testing should occur, and whether a result needs confirmation. Ask how to protect household members from blood contact and whether your medicines or supplements need review.
