A silent infection that’s now curable
Hepatitis C can damage the liver for decades without symptoms. A short course of tablets now cures most people - so testing every adult once makes sense.
Once
“Who should test?”
All adults, at least once.
Everyone
Positive antibody
“Do I have it?”
A second test checks for active virus.
Confirm
Cure
“Can it be treated?”
8–12 weeks of tablets cures most people.
Curable
Is it right for you?
Worth considering if…
- You’ve never been tested.
- You’ve had blood transfusions before 1992, injected drugs or had tattoos in unregulated settings.
A better option if…
- You’ve tested negative and have no new risk - no need to repeat.
