Paying cash: what to do
- Check your local health department or a Title X family planning clinic, which offer free or sliding-fee STD testing in many areas.
- Ask whether chlamydia and gonorrhea will be billed as two tests or as one combined price, and whether the visit fee is included.
- Ask what the follow-up test costs if a screen is positive, since HIV, syphilis and hepatitis C screening results are confirmed with a second test.
