STI screening costs range from $0 to roughly $250 per visit depending on your insurance status, income, and where you go. Many people qualify for free testing and don’t realize it. The price swings dramatically based on which infections you’re tested for, whether you have insurance, and whether you visit a private doctor, a walk-in lab, or a community clinic.
What Insurance Covers at No Cost
Under the Affordable Care Act, most private health insurance plans must cover certain STI screenings with zero out-of-pocket cost. This applies to non-grandfathered plans, Medicare, Medicaid expansion plans, and many traditional Medicaid plans. The key word is “certain.” Not every STI test is automatically free. Coverage depends on your age, sex, and risk factors.
Chlamydia and gonorrhea screening is covered without cost-sharing for sexually active women 24 and younger, and for older women at increased risk. Men who have sex with men also qualify for covered screening under pediatric and adolescent guidelines through age 21. Syphilis screening is covered for anyone at increased risk, plus all pregnant women. HPV screening is covered for women aged 21 to 65 as part of cervical cancer screening (Pap tests), on schedules that vary by age.
HIV testing is also widely covered under ACA preventive services, though it wasn’t detailed in the same screening tables. If you have insurance and fall into one of these recommended groups, your plan should cover the lab work and office visit at no charge. If your insurer tries to bill you for a preventive screening that should be covered, it’s worth calling to dispute it.
The catch: if you’re outside the recommended groups (for example, a man under 25 requesting a chlamydia test who isn’t in a higher-risk category), your plan may not be required to cover it as preventive care. In that case, you could face copays or the full lab fee.
Costs Without Insurance
Without insurance, the price depends heavily on where you go. A standard doctor’s office visit runs $100 to $250 before any lab work. Lab fees for STI panels vary by which infections are included. A single test (chlamydia alone, for instance) costs less than a comprehensive panel covering chlamydia, gonorrhea, syphilis, HIV, hepatitis B, and herpes.
Direct-to-consumer lab companies like Quest Health sell individual STI tests online, but there’s often a separate physician service fee starting around $6 on top of the listed test price. That fee covers the oversight of an independent provider who reviews and orders the test. It’s small, but it’s the kind of add-on that catches people off guard.
At a private clinic, a full STI panel without insurance can easily land in the $150 to $400 range once you combine the office visit and lab processing. Individual tests are cheaper, typically $50 to $150 each, but most providers recommend testing for multiple infections at once since symptoms overlap and co-infections are common.
Sliding Scale and Free Options
Community health clinics and Planned Parenthood locations offer significantly lower prices, and many people qualify for free testing. Planned Parenthood uses a sliding scale based on household size and monthly income. For a single person earning $1,255 or less per month, services including STI office visits and lab work cost $0. A single person earning roughly $1,256 to $1,883 per month would pay around $91 for an STI office visit with labs included. At the highest income tier (above about $3,139 per month for a single person), the visit costs $229. STI treatment with medication ranges from $0 at the lowest income level to $144 at the highest tier. These are cash prices with lab fees already bundled in, though medication costs may be separate.
The sliding scale adjusts for household size. A family of four earning $2,600 or less per month qualifies for the $0 tier. The thresholds increase with each additional household member.
Title X funded family planning clinics operate under federal rules that are even more explicit. If your documented income is at or below 100% of the federal poverty level, you cannot be charged for services. Between 101% and 250% of the poverty level, you receive a discount based on ability to pay. Above 250%, you’ll be charged on a fee schedule designed to recover the clinic’s costs, but fees can still be waived if a site director determines you can’t pay for good cause. Importantly, minors receiving confidential services have their eligibility based on their own income, not their parents’.
Local health departments also run STI clinics, often offering free HIV and syphilis testing regardless of income. Availability varies by county, so searching for your local health department’s sexual health services page is the fastest way to find what’s offered near you.
What Affects the Final Price
Several factors determine what you’ll actually pay:
- Number of infections tested. Testing for one STI is cheaper than a full panel. But if you’re getting tested, most providers recommend screening for at least chlamydia, gonorrhea, syphilis, and HIV together.
- Type of test. Blood draws (used for HIV, syphilis, herpes, hepatitis) and urine or swab tests (used for chlamydia and gonorrhea) have different processing costs. Herpes blood tests tend to be on the pricier side when ordered individually.
- Where you go. A private doctor’s office with separate lab billing is the most expensive route. Walk-in labs, community clinics, and Planned Parenthood locations bundle fees and offer discounts.
- Whether treatment is needed. Testing and treatment are billed separately. If a test comes back positive, you’ll face additional costs for medication. Generic prescriptions are substantially cheaper than brand-name versions, so always ask for generics.
Treatment Costs if You Test Positive
Testing is only half the equation. If results come back positive, treatment adds to the total. Bacterial infections like chlamydia, gonorrhea, and syphilis are cured with antibiotics, and generic versions of these medications are relatively affordable. At Planned Parenthood on the sliding scale, STI treatment with medication ranges from $0 to $144 depending on income.
At a retail pharmacy without insurance, antibiotic costs vary widely depending on the pharmacy, the specific drug, and whether you use a discount card or coupon program. Viral infections like herpes require antiviral medications that manage outbreaks rather than cure the infection, and ongoing prescriptions add up over time. Pharmacy discount programs like GoodRx can cut costs significantly for both antibiotics and antivirals, so it’s worth checking prices across multiple pharmacies before filling a prescription.
How to Keep Costs as Low as Possible
If you have insurance, confirm with your plan that the specific screenings you want are classified as preventive care before your visit. The difference between “preventive” and “diagnostic” coding can mean the difference between $0 and a full bill. If your doctor orders a test because you have symptoms, it may be coded as diagnostic rather than preventive, which changes your cost-sharing.
If you’re uninsured or underinsured, start with your local health department or a Title X clinic. You can find the nearest Title X site through the HHS Office of Population Affairs website. Planned Parenthood is another strong option, especially if your income qualifies you for reduced or zero-cost care. Many of these clinics don’t require appointments for STI testing, and they won’t turn you away for inability to pay.
Direct-to-consumer lab services can be convenient if you want to skip the office visit, but compare total costs carefully. The advertised test price plus the physician oversight fee plus any follow-up consultation can approach what you’d pay at a clinic that bundles everything together.
