Infection 1: HIV (Human Immunodeficiency Virus) Types 1 and 2
What It Is
HIV is a virus that attacks the immune system, specifically CD4 T cells, which are critical for fighting infections. Without treatment, HIV progressively weakens the immune system, eventually leading to AIDS (acquired immunodeficiency syndrome). HIV-1 is the most common type worldwide, while HIV-2 is less common and primarily found in West Africa.
How It Is Tested
The 10 panel STD test uses a 4th generation HIV antigen/antibody combination test, which is the most advanced HIV screening method available. This test detects both HIV antibodies (the immune system's response to the virus) and the p24 antigen (a viral protein that appears before antibodies develop).
Testing Window and Accuracy
- Earliest detection: 14 days after exposure (p24 antigen detection)
- Reliable detection: 4-6 weeks after exposure
- Definitive result: 12 weeks after exposure
- Sensitivity: > 99.5% after the window period
- Specificity: > 99.5%
What Results Mean
| Result | Interpretation |
|---|---|
| Negative | No HIV detected. If tested within the window period, repeat testing is recommended. |
| Positive (screening) | Preliminary positive. Requires confirmatory testing with HIV-1/HIV-2 differentiation immunoassay. |
| Confirmed positive | HIV infection confirmed. Immediate referral to HIV treatment specialist for antiretroviral therapy (ART). |
Treatment
HIV is not curable but is highly manageable with antiretroviral therapy (ART). When taken consistently, ART can reduce the viral load to undetectable levels, allowing people with HIV to live long, healthy lives and eliminating the risk of sexual transmission (undetectable = untransmittable, or U=U).
Infection 2: Syphilis
What It Is
Syphilis is a bacterial infection caused by Treponema pallidum. It progresses through four stages (primary, secondary, latent, and tertiary) and can affect virtually any organ system if left untreated. According to the CDC, syphilis rates have been increasing in the United States, reaching the highest levels since the 1950s.
How It Is Tested
Syphilis testing in the 10 panel uses a two-step approach:
- Screening test: Rapid Plasma Reagin (RPR) detects non-treponemal antibodies that indicate active or recent infection.
- Confirmatory test: Treponema pallidum particle agglutination (TPPA) or fluorescent treponemal antibody absorption (FTA-ABS) detects treponemal-specific antibodies, confirming exposure to the bacterium.
Testing Window and Accuracy
- Earliest detection: 3 weeks after exposure
- Reliable detection: 6 weeks after exposure
- Definitive result: 12 weeks after exposure
What Results Mean
| RPR Result | Confirmatory Result | Interpretation |
|---|---|---|
| Positive | Positive | Active or previously treated syphilis |
| Positive | Negative | Biological false positive (may occur in pregnancy, autoimmune conditions) |
| Negative | Positive | Past treated syphilis or very early infection |
| Negative | Negative | No evidence of syphilis |
Treatment
Syphilis is curable with antibiotics. Primary, secondary, and early latent syphilis are treated with a single intramuscular injection of penicillin G benzathine. Late latent and tertiary syphilis require three weekly injections. Neurosyphilis requires intravenous penicillin.
Infection 3: Hepatitis B
What It Is
Hepatitis B is a viral infection that attacks the liver, causing both acute and chronic disease. Chronic hepatitis B can lead to cirrhosis, liver failure, and liver cancer. The World Health Organization estimates that 296 million people worldwide were living with chronic hepatitis B as of recent data.
How It Is Tested
The 10 panel STD test includes a hepatitis B panel that measures three markers:
| Marker | Full Name | What It Detects |
|---|---|---|
| HBsAg | Hepatitis B surface antigen | Active infection (current) |
| HBsAb | Hepatitis B surface antibody | Immunity (from vaccination or past infection) |
| HBcAb | Hepatitis B core antibody | Past or present infection |
Testing Window
- Earliest detection: 4 weeks after exposure (HBsAg)
- Reliable detection: 8-12 weeks after exposure
- Window period: Up to 9 weeks for HBsAg to become detectable
What Results Mean
| HBsAg | HBsAb | HBcAb | Interpretation |
|---|---|---|---|
| Negative | Positive | Negative | Immune from vaccination |
| Negative | Positive | Positive | Immune from past infection (natural immunity) |
| Positive | Negative | Positive | Acute or chronic hepatitis B infection |
| Negative | Negative | Negative | Not immune, never exposed, candidate for vaccination |
| Negative | Negative | Positive | Four possibilities: early infection, past resolved infection, chronic infection with low antigen, false positive |
Treatment
Acute hepatitis B often resolves on its own. Chronic hepatitis B is treated with antiviral medications such as tenofovir or entecavir, which can suppress viral replication and reduce the risk of liver complications. Hepatitis B is preventable through vaccination, which is recommended for all adults who are not already immune.
Infection 4: Hepatitis C
What It Is
Hepatitis C is a bloodborne virus that primarily infects the liver. According to the CDC, approximately 2.4 million adults in the United States are living with hepatitis C. It is transmitted through blood-to-blood contact, including through sexual contact, though sexual transmission is less efficient than for other STIs.
How It Is Tested
Testing follows a two-step process:
- HCV antibody test: Screens for exposure to the virus.
- HCV RNA test (reflex): If the antibody test is positive, an RNA test confirms active infection by detecting the virus's genetic material.
Testing Window
- Antibody detection: 4-12 weeks after exposure
- RNA detection: 1-3 weeks after exposure
- Recommended testing: 8-12 weeks after exposure for comprehensive results
What Results Mean
| Antibody | RNA | Interpretation |
|---|---|---|
| Negative | Not performed | No evidence of hepatitis C exposure |
| Positive | Positive | Active hepatitis C infection |
| Positive | Negative | Past infection that resolved spontaneously or was treated |
Treatment
Hepatitis C is curable with direct-acting antiviral (DAA) medications. Treatment typically lasts 8-12 weeks and achieves cure rates exceeding 95%. The CDC recommends that all adults aged 18-79 be screened for hepatitis C at least once, regardless of risk factors.
Infection 5 and 6: Herpes Simplex Virus (HSV-1 and HSV-2)
What They Are
Herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) are lifelong viral infections. HSV-1 traditionally causes oral herpes (cold sores), but increasingly causes genital herpes as well. HSV-2 primarily causes genital herpes. Both types can be transmitted even when no symptoms are present through asymptomatic viral shedding.
How They Are Tested
The 10 panel STD test uses type-specific IgG antibody tests that can distinguish between HSV-1 and HSV-2. This is important because non-type-specific tests cannot differentiate between the two viruses, which have different implications for management and transmission.
Testing Window
- Earliest antibody detection: 4 weeks after exposure
- Reliable detection: 12-16 weeks after exposure
- Full seroconversion: Up to 16 weeks
What Results Mean
| Result | Interpretation |
|---|---|
| HSV-1 IgG positive, HSV-2 IgG negative | Past exposure to HSV-1. Cannot determine if infection is oral or genital based on blood test alone. |
| HSV-1 IgG negative, HSV-2 IgG positive | Past exposure to HSV-2. Most likely genital herpes. |
| Both positive | Past exposure to both HSV-1 and HSV-2. |
| Both negative | No evidence of HSV-1 or HSV-2 exposure. If tested before 12 weeks, repeat testing may be needed. |
Treatment
Herpes is not curable but is manageable with antiviral medications. Daily suppressive therapy with valacyclovir, acyclovir, or famciclovir reduces outbreak frequency, symptom severity, and transmission risk. Episodic treatment shortens the duration of individual outbreaks.
Infection 7: Chlamydia
What It Is
Chlamydia, caused by Chlamydia trachomatis, is the most commonly reported sexually transmitted infection in the United States. The CDC reports over 1.6 million cases annually. Chlamydia can infect the genitals, rectum, and throat. If untreated, it can cause pelvic inflammatory disease (PID) in women, leading to infertility and chronic pelvic pain, and epididymitis in men.
How It Is Tested
Testing uses nucleic acid amplification testing (NAAT), which detects the genetic material of the bacteria. NAAT is the gold standard for chlamydia detection due to its high sensitivity and specificity.
Testing Window
- Earliest detection: 1-2 days after exposure
- Reliable detection: 5-7 days after exposure
- Recommended testing: 7 days after exposure
What Results Mean
| Result | Interpretation |
|---|---|
| Negative | No chlamydia detected at the time of testing |
| Positive | Active chlamydia infection requiring treatment |
Treatment
Chlamydia is curable with antibiotics. The CDC recommends doxycycline 100 mg twice daily for 7 days as first-line treatment. A single dose of azithromycin is an alternative regimen. All sexual partners from the past 60 days should also be tested and treated. Retesting is recommended 3 months after treatment to detect reinfection.
Infection 8: Gonorrhea
What It Is
Gonorrhea is caused by the bacterium Neisseria gonorrhoeae. It can infect the genitals, rectum, and throat. Like chlamydia, gonorrhea is often asymptomatic, particularly in women. Untreated gonorrhea can cause PID, infertility, and can spread to the blood and joints (disseminated gonococcal infection).
How It Is Tested
Testing uses NAAT on urine samples or swabs. NAAT is more sensitive than traditional culture methods and can detect low-level infections that culture might miss.
Testing Window
- Earliest detection: 1-2 days after exposure
- Reliable detection: 5-7 days after exposure
- Recommended testing: 7 days after exposure
What Results Mean
| Result | Interpretation |
|---|---|
| Negative | No gonorrhea detected at the time of testing |
| Positive | Active gonorrhea infection requiring treatment |
Treatment
Gonorrhea is treated with antibiotics, though antimicrobial resistance is a growing concern. The CDC currently recommends a single 500 mg intramuscular injection of ceftriaxone for uncomplicated infections. If chlamydia has not been ruled out, doxycycline is added to cover potential co-infection.
Infection 9: Trichomoniasis
What It Is
Trichomoniasis (or "trich") is caused by the single-celled parasite Trichomonas vaginalis. It is the most common curable STI, with an estimated 2.6 million cases in the United States. In women, trichomoniasis can cause vaginitis with frothy discharge, itching, and irritation. In men, it is often asymptomatic but can cause urethritis. Trichomoniasis increases the risk of acquiring and transmitting HIV.
How It Is Tested
NAAT testing is the most sensitive method for detecting trichomoniasis and is the method used in the 10 panel STD test. NAAT can detect the parasite in urine samples, vaginal swabs, or urethral swabs with significantly higher sensitivity than traditional wet mount microscopy.
Testing Window
- Earliest detection: 3 days after exposure
- Reliable detection: 7 days after exposure
What Results Mean
| Result | Interpretation |
|---|---|
| Negative | No trichomoniasis detected |
| Positive | Active trichomoniasis infection requiring treatment |
Treatment
Trichomoniasis is curable with a single dose of metronidazole (2 grams orally) or tinidazole (2 grams orally). Both sexual partners should be treated simultaneously to prevent reinfection. Alcohol should be avoided for 72 hours after taking metronidazole due to the disulfiram-like reaction.
Infection 10: Mycoplasma genitalium
What It Is
Mycoplasma genitalium is an emerging sexually transmitted bacterium that is increasingly recognized as a significant cause of urethritis in men and cervicitis, PID, and infertility in women. The CDC has identified it as a pathogen of concern due to rising rates of antibiotic resistance.
How It Is Tested
Testing uses NAAT to detect the bacterium's genetic material in urine or swab samples. M. genitalium is too small to be seen under a regular microscope and is difficult to culture, making NAAT the only reliable testing method.
Testing Window
- Earliest detection: 1-2 weeks after exposure
- Reliable detection: 2-3 weeks after exposure
What Results Mean
| Result | Interpretation |
|---|---|
| Negative | No Mycoplasma genitalium detected |
| Positive | Active infection requiring antibiotic treatment |
Treatment
M. genitalium treatment is complicated by increasing antibiotic resistance. The CDC recommends a two-stage approach: initial treatment with doxycycline followed by azithromycin or moxifloxacin if resistance testing is not available. Resistance-guided therapy using macrolide resistance testing is the preferred approach when available.

Frequently Asked Questions
What is tested for in an STD 10 panel test?
An STD 10 panel test screens for ten infections: HIV (types 1 and 2), syphilis, hepatitis B, hepatitis C, herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2), chlamydia, gonorrhea, trichomoniasis, and mycoplasma genitalium. The test uses blood samples for viral and antibody-based tests and urine samples for bacterial and parasitic NAAT tests. This comprehensive panel covers the most common and clinically significant sexually transmitted infections.
What is included in a 10 panel STD test beyond the infections themselves?
Beyond the ten infection screenings, a comprehensive 10 panel STD test typically includes collection of both blood and urine samples, laboratory processing, result reporting, and often post-test counseling or physician consultation. Some providers include confirmatory testing for positive screening results (such as HCV RNA for positive hepatitis C antibody tests), partner notification resources, and treatment referrals. The specific inclusions vary by provider, so verify what is covered when you order your test.
Can a 10 panel STD test detect all STIs?
No, a 10 panel STD test does not detect all sexually transmitted infections. It covers the ten most common and clinically significant infections, but it does not include testing for HPV (human papillomavirus), pubic lice (crabs), scabies, molluscum contagiosum, lymphogranuloma venereum (LGV), or donovanosis. HPV is particularly notable because it is the most common STI but is typically screened through Pap smears and HPV DNA tests rather than blood or urine testing. Discuss additional testing with your healthcare provider if you have concerns about specific infections.
How is a 10 panel STD test different from a routine STD test?
A routine STD test typically screens for 3-5 of the most common infections, usually HIV, syphilis, chlamydia, and gonorrhea. A 10 panel STD test is significantly more comprehensive, adding hepatitis B, hepatitis C, both types of herpes (HSV-1 and HSV-2), trichomoniasis, and mycoplasma genitalium. The 10 panel is appropriate for people who want a thorough evaluation of their sexual health, have multiple risk factors, or want the most comprehensive screening available in a single testing session.
What samples are needed for a 10 panel STD test?
A 10 panel STD test requires two types of samples. A blood sample drawn from a vein in your arm is used for testing HIV, syphilis, hepatitis B, hepatitis C, and herpes (HSV-1 and HSV-2). A urine sample, specifically the first-catch portion of your urine stream, is used for NAAT testing of chlamydia, gonorrhea, trichomoniasis, and mycoplasma genitalium. In some cases, depending on the provider and your sexual practices, additional swab samples from the throat or rectum may be recommended for more comprehensive screening.
What should I do if one of my 10 panel STD test results is positive?
If any result on your 10 panel STD test is positive, the most important step is to follow up with a healthcare provider promptly. They will confirm the result with any necessary additional testing, explain what the result means for your health, prescribe appropriate treatment, and discuss partner notification. Most infections in the panel are curable with antibiotics, and those that are not curable are manageable with medication. Avoid sexual contact until you have consulted with your provider and completed any recommended treatment. Notify all recent sexual partners so they can also be tested.
The Bottom Line
The 10 panel STD test provides comprehensive screening for ten of the most clinically significant sexually transmitted infections. Each infection included in the panel has specific testing methods, detection windows, and treatment options. Understanding what is tested for in an STD 10 panel test empowers you to make informed decisions about your sexual health and ensures you receive the most thorough screening available.
Whether you are starting a new relationship, have had a potential exposure, or simply want a routine checkup, the 10 panel STD test offers peace of mind through comprehensive coverage. Most infections it detects are curable, and early treatment prevents complications and further transmission.
