17 markers in this category
Anti-HAV (Hepatitis A Antibody)
The hepatitis A test measures anti-HAV antibodies, which can show whether you are likely protected against hepatitis A through vaccination or a past infection. It gives a clear preventive data point about your immunity status. A doctor can interpret the result.
Anti-HBs (Hepatitis B Immunity)
The hepatitis B immunity test measures anti-HBs antibodies, which can show whether you are likely protected against hepatitis B through vaccination or recovery from a past infection. It is often used to confirm a vaccination response. A doctor can interpret the level for you.
Chlamydia (PCR)
This PCR test looks for the DNA of Chlamydia trachomatis, the most common bacterial STI. The sample is usually urine or a swab, not blood. It can give you clarity even when there are no symptoms.
Chlamydia IgG
This blood test looks for IgG antibodies, which can indicate past or earlier exposure to chlamydia rather than a current acute infection. It is sometimes used when looking into fertility questions. It can add context to your wider health picture.
Gonorrhea (PCR)
This PCR test looks for the DNA of Neisseria gonorrhoeae, the bacterium behind gonorrhea. The sample is usually urine or a swab, not blood. It can provide clarity even when there are no symptoms.
HIV 1/2 Antibody + p24 Antigen
This 4th-generation combination blood test looks for both HIV antibodies and the p24 antigen, which together allow relatively early detection. It can offer clarity and peace of mind after a possible exposure. A positive result is not a diagnosis on its own and would always need confirmatory testing.
HIV Screening
HIV screening is a blood test for HIV antibodies and antigen, often used for routine, peace-of-mind checks. It can give clarity about your status without you needing any symptoms. A reactive result is never a diagnosis on its own and would always be confirmed with further testing.
HIV-RNA PCR
An HIV RNA test uses PCR to detect the genetic material (RNA) of the virus directly, which allows some of the earliest possible detection. It is a more specialized, higher-cost test often considered after a recent possible exposure. A result would always be interpreted by a doctor, and any reactive finding needs confirmatory testing.
Hepatitis B Core Antibody
The anti-HBc test detects hepatitis B core antibodies, which can indicate past or present exposure to the hepatitis B virus. On its own it does not confirm a current infection. A doctor interprets it alongside other markers such as HBsAg and anti-HBs.
Hepatitis B Surface Antigen
The hepatitis B test detects HBsAg, a marker that can indicate an active hepatitis B infection, whether acute or chronic. It is a data point that needs professional interpretation, not a diagnosis. A doctor can advise on further evaluation.
Hepatitis C Antibody
The hepatitis C test detects anti-HCV antibodies, which can indicate exposure to the hepatitis C virus. A positive result does not confirm a current active infection on its own. A doctor can arrange confirmatory RNA testing to clarify the picture.
Herpes Simplex 1 IgG
This herpes test (HSV-1) is a blood antibody (IgG) test that can show whether you have had earlier contact with herpes simplex virus type 1, which is commonly oral but can also be genital. An IgG result reflects past exposure, not necessarily a current or recent infection. It cannot tell you where or when contact occurred.
Herpes Simplex 2 IgG
This herpes test (HSV-2) is a blood antibody (IgG) test that can show whether you have had earlier contact with herpes simplex virus type 2, which is commonly genital. An IgG result reflects past exposure, not necessarily a current or recent infection. It cannot tell you where or when contact occurred.
Mycoplasma Genitalium
This PCR test looks for the DNA of Mycoplasma genitalium, an increasingly recognized STI. The sample is usually urine or a swab, not blood. It can give you clarity even when there are no symptoms.
Syphilis (VDRL)
The syphilis VDRL (RPR) is a non-treponemal blood test that can reflect disease activity and is also used to follow how the body responds over time. It gives a data point, not a diagnosis. A doctor can interpret it alongside other tests.
Syphilis Screening
Syphilis screening is a treponemal antibody blood test that looks for antibodies the body may form after contact with the syphilis bacterium. It is a screening data point, not a diagnosis. A doctor can interpret it alongside other tests.
Trichomoniasis (PCR)
This PCR test looks for the DNA of Trichomonas vaginalis, the parasite behind trichomoniasis. The sample is usually urine or a swab, not blood. It can offer clarity when you are unsure about possible symptoms.
