Short answer
There is no single standard "full STI panel." A clinic, lab, app, or at-home kit may use that phrase to mean different combinations of HIV, syphilis, chlamydia, gonorrhea, hepatitis, trichomoniasis, herpes, HPV-related cervical screening, Mycoplasma genitalium, BV, yeast, UTI-related urine tests, pelvic exam findings, or other tests. The safer question is not "Is it full?" but "Which infections, body sites, test types, and time windows does this cover?"
What a panel may include
| Infection | Common sample type | Important caveat |
|---|---|---|
| HIV | Blood, oral fluid, or self-test depending on test type. | Window period matters. A negative result may need repeat testing based on timing. |
| Syphilis | Blood. | CDC says diagnosis usually relies on both nontreponemal and treponemal tests interpreted with history. |
| Chlamydia | Urine or swab. | Urine alone may miss rectal or throat infection if those sites were exposed. |
| Gonorrhea | Urine or swab. | Throat and rectal testing can matter for oral or anal exposure. |
| Hepatitis B or hepatitis C | Blood. | Testing depends on vaccination, pregnancy, injection-drug equipment exposure, HIV status, and other risks. See the hepatitis B and C testing guide. |
| PrEP or PEP questions | HIV tests, STI screening, kidney function, liver enzymes, hepatitis testing, or pregnancy testing depending on the prevention question. | PrEP labs and PEP follow-up are prevention care, not a one-time full STI panel. See the PrEP vs PEP testing timelines guide and the PrEP labs and STI testing follow-up guide. |
| Trichomoniasis | Swab or urine depending on test and anatomy. | CDC says no general screening recommendation is available for everyone; testing is often symptom- or risk-based. See the trichomoniasis testing guide. |
| HPV/Pap cervical screening | Cervical or vaginal specimen depending on test, age, and collection method. | HPV tests and Pap tests are mainly cervical cancer screening tools, not general STI-panel tests. See the HPV testing and Pap tests guide. |
| Mycoplasma genitalium | Urine or swab sample depending on anatomy and test. | CDC does not recommend routine screening for asymptomatic people; testing is targeted for persistent or recurrent symptoms. See the Mycoplasma genitalium testing guide. |
| BV or yeast | Vaginal swab, pH, microscopy, culture, or molecular vaginitis panel. | BV and yeast tests can explain vaginal symptoms, but they are not the same as HIV, syphilis, chlamydia, gonorrhea, or hepatitis testing. See the BV and yeast testing versus STI testing guide. |
| UTI evaluation | Urinalysis or urine culture. | UTI testing can explain urinary symptoms, but it is not the same as STI urine NAAT testing. See the UTI testing versus STI testing guide. |
| Pelvic exam | Physical exam; may include speculum or bimanual components depending on the visit. | A pelvic exam is not automatically a lab test for STIs. See the pelvic exam versus STI testing guide. |
| Herpes | Swab from a sore, or blood in selected situations. | CDC and USPSTF do not recommend routine herpes blood-test screening for most people without symptoms. |
Why body site matters
CDC says STI testing may involve blood, urine, or swabs from the vagina, throat, or rectum. Chlamydia and gonorrhea testing is especially site-dependent. If exposure happened through oral sex, anal sex, or a shared sex toy that moved between partners or body sites, a urine or genital-only test may not answer the whole question. See the extragenital STI testing guide, the STI testing after oral sex guide, the STI testing after anal sex guide, the STI testing after sharing sex toys guide, and the chlamydia and gonorrhea testing guide for site-specific testing details.
Why timing matters
Some tests can be negative early after exposure even if an infection is developing. HIV tests have different window periods, and syphilis or other infections may need repeat testing depending on timing and symptoms. A panel done too soon can create false reassurance. Symptoms can also require diagnostic testing beyond a routine panel. See the HIV testing window period guide, the condom break and exposure guide, the STI testing after a new partner guide, the STI testing after vacation or travel sex guide, the STI testing before stopping condoms guide, the open relationship and multiple-partner testing guide, and the STI symptoms versus routine screening guide.
Why herpes is different
Herpes is often the most confusing "full panel" question. CDC says herpes blood tests may be used when someone has no sores, but routine screening is not recommended for most people without symptoms because false positives and unclear results can cause harm. If sores are present, a swab from the lesion is usually a different question than routine blood screening. See the herpes testing guide.
Why HPV and Pap tests are different
HPV is sexually transmitted, but HPV tests and Pap tests are usually used for cervical cancer screening and follow-up, not as broad STI tests. They do not replace testing for infections such as HIV, syphilis, chlamydia, gonorrhea, hepatitis, herpes, or trichomoniasis. See the HPV testing and Pap tests guide.
Why Mycoplasma genitalium is different
Mycoplasma genitalium testing is usually a targeted follow-up question when urethritis, cervicitis, or PID concerns persist or recur. CDC does not recommend routine screening of asymptomatic people or extragenital Mgen testing. See the Mycoplasma genitalium testing guide.
Why BV and yeast are different
BV and yeast are common vaginitis questions, not stand-alone proof that a full STI screen was done. A vaginal panel may include BV, Candida, and trichomoniasis while omitting HIV, syphilis, hepatitis, chlamydia, or gonorrhea. See the BV and yeast testing versus STI testing guide.
Why UTI testing is different
A urinalysis or urine culture can help evaluate a urinary tract infection, but it does not automatically test for chlamydia, gonorrhea, HIV, syphilis, hepatitis, herpes, or other STIs. If urinary symptoms overlap with exposure concerns, ask whether STI NAATs, swabs, or blood tests are also needed. See the UTI testing versus STI testing guide.
Why a pelvic exam is different
A pelvic exam is a physical exam, not a named lab panel. STI testing may be collected during an exam, but it can also use urine, blood, self-collected vaginal swabs, throat swabs, or rectal swabs. See the pelvic exam versus STI testing guide.
Questions to ask before buying or booking
- Which infections are included by name?
- Which infections are not included?
- Does the test include throat, rectal, vaginal, cervical, urethral, urine, and blood testing when relevant?
- Is this screening, diagnostic testing for symptoms, or follow-up after a known exposure?
- Is the timing right, or should I repeat testing later?
- If anything is positive, who provides treatment, partner notification support, or confirmatory testing?
