STI Panels: What They Cover and What They Cost

What an STI Panel Is

An STI panel is a group of tests for sexually transmitted infections sold as one order. Instead of buying a separate test for each infection, you buy a bundle that covers several at once. The sample is collected in a single visit, and the results come back together. This is the same bundling logic used for metabolic or wellness panels, applied to a specific group of infections.

Panels are screening tools. A result indicates whether evidence of an infection was detected in your sample. What that means for you, and whether follow-up is needed, is a clinical question.

What Panels Commonly Include

Coverage varies widely. Smaller panels may focus on two or three of the most common infections, while comprehensive panels can include a longer list. Common components include:

• Chlamydia and gonorrhea, often tested from a urine sample
• HIV, tested from blood
• Syphilis, tested from blood
• Hepatitis B and C, tested from blood
• Trichomonas, often tested from urine
• Herpes simplex, tested from blood

Some infections require a specific sample type or collection method, which is why a broad panel may involve both a blood draw and a urine sample. Always read the component list rather than assuming what a panel covers.

How STI Panels Are Priced

Price tracks breadth. A two-infection panel costs less than a ten-infection panel because it bundles less analytical work. The collection fee is usually charged once, so adding more infections to a panel raises the total more slowly than buying them individually. That is the main cost advantage of a panel: one collection, one processing sequence, many tests.

Comparing Panels Fairly

Two panels with similar names can differ in what they include. To compare them, list the infections each one covers and note the sample types. A cheaper panel that omits an infection you want is not actually cheaper for your situation. Add the price of any missing test, then compare the totals. Pay attention to whether the report distinguishes between current infection and past exposure, since that framing affects how a clinician interprets the result.

How to Order a Test and Where to Get Tested

Review the component list, choose the panel, and pay. Then visit a collection site during open hours or at your appointment time. Bring photo identification and your confirmation. If the panel needs both blood and urine, both will be collected in the same visit. Samples go to a CLIA-certified laboratory, and results are posted to your secure account.

How Much Does It Cost

Cost depends on the number of infections covered and the sample types required. A focused panel is the least expensive; a comprehensive panel has the highest total but a lower cost per infection. Collection and reporting are typically included. Because screening recommendations depend on individual risk factors, a clinician is the right person to advise which infections are worth testing for you.

Panel size	Relative cost	Best for
Focused (2–3 infections)	Lower	Targeted screening
Broad (6–10 infections)	Higher	Comprehensive screening

A Note on Results and Privacy

Results are confidential and delivered through a secure account. A positive result is a prompt to speak with a clinician about confirmation and next steps, not a conclusion on its own. This article is general information, not medical advice.

How Panel Breadth Changes the Price

STI panels sit on a spectrum from a single marker to a broad bundle, and the price tracks that breadth. A single test such as one for chlamydia is inexpensive because it measures one thing, while a panel that adds gonorrhea, HIV, syphilis, and hepatitis covers more ground and costs more. The per-marker value usually improves as the panel grows, but only if you actually need the additional markers. Choosing a panel by its list rather than its name is the way to match the price to the information you want.

Panel size	Typical trade-off
Single marker	Lowest price, narrowest coverage
Small bundle	Moderate price, covers related markers
Broad panel	Higher price, best per-marker value if most are needed

Verification Before You Order

Before paying, read the component list and confirm that collection and any required review are included in the total. Check the turnaround, since some panels include a marker that takes longer to process. Ask how a repeat draw would be billed and where the result will be delivered. A panel is good value when its price, coverage, and turnaround fit your situation, and those details are all visible in the order before you commit.
