THE INFECTION

What is hepatitis C?

Cause
A virus that infects the liver
Also called
HCV infection · Hepatitis C virus

Hepatitis C is a viral infection of the liver caused by the hepatitis C virus (HCV). It spreads mainly through blood: shared needles and drug equipment, unsterile medical, dental, tattoo or piercing procedures, and, less commonly, sex that involves contact with blood.

About three in ten people clear the virus by themselves within six months. In the rest, hepatitis C becomes chronic and can quietly damage the liver over many years, leading to cirrhosis or liver cancer. Because a new infection rarely causes symptoms, most people only find out through a blood test.

Hepatitis C is now one of the most satisfying infections to find. There is no vaccine, but a course of antiviral tablets cures more than 95% of people. Testing is a simple two-step process: an antibody test first, then an RNA test to confirm whether the virus is still active.

Symptoms of hepatitis C.

Most new infections cause no symptoms. When they do, they appear weeks to months after exposure and are easy to confuse with other illnesses.

New (acute) infection

  • Tiredness
  • Fever
  • Nausea and loss of appetite
  • Yellow skin or eyes (jaundice)
  • Dark urine

Long-term (chronic) infection

  • Usually no symptoms for years
  • Fatigue or 'brain fog'
  • Later, signs of liver scarring
  • Often found by chance on a blood test

Chronic hepatitis C can damage the liver for decades without symptoms. A blood test finds it, and treatment cures it.

How the hepatitis C test works.

Hepatitis C testing has two steps, so a single positive result is never the full answer.

  • HCV antibody test

    Blood

    The screening test. Shows infection at any time, past or present. Takes around 8 to 11 weeks to become positive.

  • HCV RNA test

    Blood

    Confirms whether the virus is active now, and detects infection earlier, from about 1 to 2 weeks. Also confirms a cure after treatment.

Testing with Ovio

  1. Tell us what you needCall or message Ovio, privately. Say where you are in Bangkok and when suits you.
  2. A doctor comes to youAt your home, condo, hotel or office. The doctor asks about your concerns and recommends the right samples.
  3. Samples go to the laboratoryTaken there and then; for most tests the visit itself is short.
  4. Your result, explainedWhat it means, and what to do next if anything needs treatment or a repeat test.

Not sure which test you need?

Speak to one of our doctors. They will ask about your situation and suggest the tests, samples and timing that fit it.

When to test for hepatitis C.

Every test has a window period: the time after exposure before it can reliably detect an infection. A test taken too early can be negative even when the infection is there.

TestSampleTiming after exposureGood to know
HCV RNABloodUsually detectable 7–14 daysCDC describes RNA as usually detectable around 1–2 weeks; sexual transmission risk varies by context.
HCV antibody, with RNA follow-up when indicatedBloodUsually detectable 56–77 daysCDC describes an 8–11-week antibody window. Antibody alone does not establish current infection.

Who should get tested

  • Every adult at least once
  • Anyone who has ever injected drugs, even once, or shared straws for snorting
  • Anyone with tattoos, piercings or medical procedures where sterility was uncertain
  • Men who have sex with men, and anyone living with HIV or taking PrEP
  • Anyone with abnormal liver test results
  • Everyone who is pregnant

AFTER THE TEST

Results and next steps.

A negative antibody test outside the window period means you have not had hepatitis C. If your risk was recent, the doctor may recommend an RNA test or a repeat antibody test later.

A positive antibody test is followed by an RNA test. If the virus is active, the next step is an assessment of the liver and a course of direct-acting antiviral tablets, which cure more than 95% of people.

Cure is confirmed by an RNA test after treatment. The antibody test will stay positive, so future checks use RNA testing.

Lowering your risk.

  • Never share needles, syringes, straws or other drug equipment
  • Never share razors, toothbrushes or nail clippers
  • Choose licensed tattoo, piercing and beauty clinics
  • Use condoms, especially for anal sex or sex that may involve blood

Hepatitis C testing:
your questions.

Can't see your question? Ask one of our doctors.

Not necessarily. A positive antibody test means you have been infected at some point. About three in ten people clear the virus naturally but keep the antibodies. An HCV RNA test is needed to show whether the virus is still active and needs treatment.
