17 markers in this category
Anti-HAV (Hepatitis A Antibody)
An Anti-HAV test is part of a comprehensive health screening that checks your immunity against hepatitis A.
Anti-HBs (Hepatitis B Immunity)
An Anti-HBs test is part of a comprehensive health screening that confirms your immunity to hepatitis B.
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.
Chlamydia IgG
After contact with a bacterium, your immune system makes IgG antibodies, proteins aimed at exactly that one germ, and according to MedlinePlus the body remembers them even after the infection has cleared.
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.
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.
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.
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.
Hepatitis B Core Antibody
According to the RIVM, after an infection with the hepatitis B virus, antibodies start forming against the hepatitis B core antigen, which surrounds the core of the virus; those antibodies are called anti-HBc.
Hepatitis B Surface Antigen
The hepatitis B test detects HBsAg, a marker that can indicate an active hepatitis B infection, whether acute or chronic.
Hepatitis C Antibody
The Hepatitis C Antibody test is part of comprehensive preventive health screening.
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.
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.
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.
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.
Syphilis Screening
Syphilis screening is a treponemal antibody blood test that looks for antibodies the body may form after contact with the syphilis bacterium.
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.
