7 Questions to Ask Before Ordering an Online STI Test

Online STI testing comes in two main forms. With lab-order services, you buy a test online and give a sample at a partner lab. With mail-in kits, you collect a sample at home and mail it to a lab. Both can be good options, and both vary a lot in the details that matter. If you want our comparison of specific services, see best at-home STD tests. This guide is the checklist behind that kind of comparison, so you can apply it to any provider.

1. Who runs the test, and is the lab CLIA-certified?

In the US, laboratory testing on human specimens for diagnosis is regulated under the Clinical Laboratory Improvement Amendments (CLIA), which set quality standards for testing labs (CMS: CLIA). A reputable service should say which lab processes your sample, or at least confirm it's CLIA-certified. If a site won't tell you, treat that as a warning sign.

For tests you do entirely at home, like a rapid HIV self-test, ask whether the product is FDA-approved or authorized. The FDA has authorized products for home use, including an OTC HIV self-test and a home test for chlamydia, gonorrhea, and trichomoniasis (FDA).

2. Which body sites are sampled?

This is where many people get a false sense of security. A chlamydia and gonorrhea test on urine only checks the urogenital site. If you've had oral or receptive anal sex, you may also need throat or rectal swabs. CDC's screening recommendations call for testing at the sites of exposure for some groups, because infections there can be missed by urine testing.

• Does the service offer throat and rectal swabs, or urine only?
• For lab-order services, will the partner lab collect those swabs, or only urine and blood?

See chlamydia and gonorrhea sample types.

3. Exactly which tests are in the panel?

"Full panel" and "10-panel" aren't standard terms. Look for the actual test names:

• HIV: antigen/antibody, antibody-only, or RNA? Each has a different window period.
• Syphilis: which test, and is a reactive result confirmed with a second test type?
• Herpes: IgG type-specific (and is a low positive confirmed?), or IgM, which CDC doesn't recommend?
• Hepatitis B: HBsAg only, or the full triple panel CDC recommends for adult screening?
• Trichomoniasis and M. genitalium: included or optional?

Bigger isn't automatically better. See 10-panel vs targeted testing.

4. What happens if a result is positive?

A result is only useful if it leads somewhere. Ask:

• Is a clinician consultation included, or does it cost extra?
• Can the service prescribe treatment, and in your state?
• Are reactive screening results (like syphilis or HIV) confirmed, or will you be sent elsewhere for that?
• Do they help with partner notification or expedited partner therapy where it's allowed?
• If they can't treat you, do they tell you where to go?

5. How long until results, and how are they delivered?

Turnaround depends on shipping, lab volume, and the tests ordered. Ask about the typical range, not just the fastest case. Also check how results are delivered: a secure portal, a phone call, or email. Find out whether a clinician reviews them before they're released.

6. What are the refund, cancellation, and expiry terms?

• Can you cancel before you collect or visit the lab?
• Does the order or kit expire?
• What happens if the lab rejects your sample? Is a replacement free?
• Can you use HSA or FSA funds, and will you get an itemized receipt?

These answers belong in the service's terms of service and FAQ. If they're hard to find, ask support before you pay.

7. How is your data handled?

Sexual health results are sensitive. Read the privacy policy for:

• Who can see your results, and whether they're shared with insurers or employers.
• How the charge appears on your card or bank statement.
• Whether your data is used for marketing or shared with advertisers.
• Whether you can delete your account and data.

Some positive results are reportable to public health departments by law, whichever service you use. That's a normal public health function, not a privacy failure. Our privacy guide covers packaging, billing, and results in more detail.

Bonus: Is now the right time to test?

Even the best service can't fix a test taken too early. Before ordering, write down your most recent possible exposure date and compare it with the window period for each test in the panel. If some tests won't be reliable yet, you have two reasonable choices: wait and order once, or test now for peace of mind and plan a repeat test later. Our window periods guide walks through the timing.

Red flags worth walking away from

• Promises of instant results for every infection. Lab tests take time, and rapid tests cover only a few infections.
• "No window period" claims. Every test has one. Honest services tell you what it is.
• Pressure tactics, like countdown timers or "today only" panels, on a medical purchase.
• No way to reach a person by phone, chat, or email before you buy.
• Results with no reference ranges or test names, only "positive/negative" with no explanation.

The checklist at a glance

When online testing isn't the best fit

Choose in-person care instead when you have significant symptoms, a possible HIV exposure within the last 72 hours (PEP is urgent), pregnancy, or a need for an exam. Online testing works best for routine screening and for exposures with no symptoms. If cost is the issue, health departments and community clinics often offer free or sliding-scale testing.
