How do I know if I should get tested?

Here are some instances that would help you figure if you need a screening test:

  1. You’re sexually active. Everyone who is sexually active (even if you’ve only ever had one partner and always use protection) should be screened at some point in your life.
  2. You’re having unprotected sex. If you’ve had or want to start having sex (vaginal, anal, or oral) with a new partner, it’s a good idea to get tested.
  3. You’re involved in riskier relationships. If your partner has a chronic or long-term infection.
  4. You engage in high-risk sexual behavior. High-risk behavior includes intimate contact with a sex worker, IV drug user, men who have sex with men, and having multiple partners, or anonymous partners. In these cases, you’re at higher risk and should get tested (remember, that includes oral and anal sex, too!)
  5. You’ve had an infection in the past. You may be more likely to have an infection again, so it’s a good idea to be screened, about 3 months after you’ve been treated, if you are sexually active.
  6. You’re a baby boomer. Because many baby boomers (people born between 1945 and 1965) may have contracted hepatitis C before we even knew the virus existed and could test for it, and because they may have no symptoms of infection, we recommend all baby boomers be tested once for hepatitis C.
  7. You have symptoms. This is a good time to have a discussion with your healthcare provider. Your symptoms and history will allow you to make the best choice about the most informative tests to look for possible causes of your symptoms.
