STD testing costs range from $0 to nearly $500 depending on where you go, how many infections you test for, and whether you have insurance. If you’re covered by a health plan that follows Affordable Care Act rules, several common tests are free. Without insurance, you still have affordable options if you know where to look.
What Insurance Covers at No Cost
Under the ACA, most health insurance plans must cover certain STD screenings with zero out-of-pocket cost. The specific tests covered at no charge include chlamydia screening for sexually active women 24 and younger (and older women at increased risk), gonorrhea screening for the same groups, syphilis screening for anyone at increased risk and all pregnant women, and HPV testing as part of cervical cancer screening for women 21 to 65. HIV screening is also covered as a preventive service. Plans must additionally cover HPV vaccination and behavioral counseling for people at higher risk of STIs.
There’s a catch: these no-cost mandates apply to preventive screening, meaning tests done because you’re in a recommended group, not because you walked in with symptoms. If you visit a doctor because you’re experiencing discharge or sores, the visit may be coded as diagnostic rather than preventive, which can trigger a copay or deductible. The tests themselves might still be covered, but the office visit charge could apply. If you want to avoid surprise bills, ask the front desk to confirm the visit will be billed as routine preventive screening before your appointment.
Costs Without Insurance
Without insurance, the price swings dramatically based on where you get tested and how many infections are included in the panel.
At a private lab like Labcorp OnDemand, a custom panel covering eight common infections (chlamydia, gonorrhea, trichomoniasis, HIV, syphilis, herpes, hepatitis B, and hepatitis C) costs $149. Their “Complete STI Test” covering seven infections runs $489, though the difference appears to reflect the testing methods used rather than just the number of infections. Other online ordering services like STDcheck and LetsGetChecked offer similar panels in the $100 to $250 range, with individual tests (just chlamydia, for example) often available for $25 to $80.
Testing a single infection is always cheaper than a full panel, but many clinicians recommend comprehensive screening since several STIs share symptoms or can be present without symptoms at all.
Sliding Scale and Low-Cost Clinics
If paying full price isn’t realistic, community health centers and nonprofit clinics are often the most affordable route. Planned Parenthood locations use a sliding scale fee based on household size and monthly income. At their Southern California locations, for instance, an STI office visit (with lab fees included) ranges from $0 for the lowest income tier to $229 for the highest. STI treatment with medication ranges from $0 to $144 on the same scale. You don’t need to be at the very bottom of the income ladder to qualify for reduced pricing. The scale is broken into five groups, so even moderate-income households typically pay less than full price.
County and city health departments often run dedicated sexual health clinics with even lower costs. The Denver Sexual Health Clinic, as one example, charges uninsured adults $20 to $90 for routine testing on a sliding scale, with the same range for symptomatic visits and treatment. Anyone 18 or younger is seen without fees. Most public health STD clinics operate on a similar model: fees are minimal, and no one is turned away for inability to pay. Many don’t require an appointment.
To find a low-cost clinic near you, search for your county’s health department STD services or use the CDC’s “GetTested” locator. Federally qualified health centers also provide STI testing on a sliding scale in every state.
Hidden Fees to Watch For
The sticker price for the lab test itself doesn’t always reflect your total bill. At a doctor’s office or urgent care, you may also be charged for the office visit (typically $100 to $300 for uninsured patients), a specimen collection or “lab draw” fee ($10 to $30), and possibly a follow-up consultation if results are positive. These charges can double or triple the cost of what you expected to pay for “just a test.”
Online lab ordering services sidestep the office visit fee by sending you directly to a blood draw location, which is one reason their total cost is often lower than a traditional doctor visit. Planned Parenthood and public health clinics generally bundle the visit and lab fees into one price, which makes costs more predictable. At Planned Parenthood specifically, lab fees are included in the quoted prices, though medication costs are separate if you need treatment.
What Treatment Costs if You Test Positive
Most bacterial STIs are curable with a short course of antibiotics. Chlamydia, the most commonly reported STI, typically costs $24 to $145 total to test and treat without insurance. Gonorrhea treatment is in a similar range. Syphilis treatment with a penicillin injection is generally inexpensive at public health clinics and sometimes provided free of charge.
Viral infections like herpes and HIV aren’t curable but are manageable with ongoing medication, which carries higher long-term costs. If you test positive for any STI and don’t have insurance, ask the clinic about patient assistance programs or generic medication options before filling a prescription at a retail pharmacy.
How Often You Need Testing
Your total yearly cost depends on how frequently you should be tested. For most sexually active adults with a single partner, annual screening is standard. People at higher risk, including men who have sex with men and people with multiple partners, benefit from testing every 3 to 6 months. The WHO recommends at least every 6 to 12 months for higher-risk groups. If you’re testing twice a year at a sliding scale clinic, your annual cost might be $40 to $180 total. At a private lab, that same frequency could run $300 to $500.
Choosing a testing location that fits your budget and sticking to a regular schedule matters more than getting the most expensive panel once. A basic screen for chlamydia, gonorrhea, syphilis, and HIV covers the most common and consequential infections, and many low-cost clinics offer exactly that combination as their standard visit.
