Hepatitis B Test
Convenient at-home test to check for a hepatitis B infection. Fast, easy-to-read, and discreet results.
Have you been exposed to hepatitis B? Get tested to find out
Hepatitis refers to inflammation and damage to the liver. The most common causes of hepatitis are three viruses known as hepatitis A, B, and C. The hepatitis B virus is a major global health problem that can cause both acute (short-term) and chronic (long-term) disease, which can develop into cirrhosis or liver cancer.
In regions of the world with the highest rates of hepatitis B, perinatal transmission (mother to child at birth) is the most common way that the virus is spread. Hepatitis B virus can also spread through needle stick injury, tattooing, piercing, sharing drug needles and syringes, and other exposures to infected blood, saliva, vaginal, and seminal fluids. Sexual transmission can occur, with more common occurrences in men who have sex with men, heterosexuals with multiple sex partners, and sex workers (and their clients).
Why consider this test?
The CDC recommends hepatitis B testing for:
- Injectable drug users
- Blood and tissue donors
- Dialysis patients
- Health care personnel who may be exposed to contaminated blood
- Children born to hepatitis B-positive mothers
- Men who have sex with men
- Individuals requiring immunosuppressive therapy
- Pregnant women
- Individuals born in countries of high hepatitis B prevalence
Symptoms of hepatitis B
Many people with acute hepatitis B infection remain asymptomatic and are unaware they are infected, but can still pass the virus to others. Symptoms of acute hepatitis B infection can include:
Nausea & vomiting
Yellowing of the skin or eyes
In some individuals, hepatitis B can develop into a chronic infection, which can lead to cirrhosis or liver cancer. Symptoms of cirrhosis and liver cancer can include:
Fatigue & weakness
Lower leg swelling
Fluid accumulation in the abdomen
What’s included in this test?
Hepatitis B Surface Antigen (HBsAg)
HBsAg is the first biomarker to become detectable, usually around four weeks after exposure to hepatitis B. HBsAg remains detectable throughout both acute (short-term) and chronic (long-term) hepatitis B infections, aside from late in an acute infection when a hepatitis B infection is resolving. When an individual has recovered from a hepatitis B infection, HBsAg will no longer be detectable in their blood.
A reactive HBsAg result indicates that the tested individual has an active hepatitis B infection, but cannot distinguish between an acute or chronic infection. This assay does not detect immunity to hepatitis B, through vaccination or a resolved past infection.

How does the Hepatitis B Test work?
A blood sample is self-collected following the detailed instructions included in the kit, and mailed back to the lab using the prepaid envelope inside the kit. Upon receipt at the laboratory, the blood sample is analyzed by a verified and approved fully automated chemiluminescent microparticle immunoassay (CMIA) to detect the hepatitis B surface antigen (HBsAg).
What are the testing recommendations for hepatitis B?
The CDC recommends screening of individuals born in countries with high hepatitis B prevalence (≥2%), as well as unvaccinated US-born children of parents born in countries with high hepatitis B prevalence. Screening should occur in pregnant women, HIV-positive individuals, injectable drug users, men who have sex with men, close contacts of infected individuals, blood and tissue donors, individuals with end-stage renal disease and those requiring immunosuppressive therapy. Infants born to infected mothers should also be tested.
Where is hepatitis B the most common?
Hepatitis B is the most prevalent in the western Pacific region and in Africa, where at least 6% of the adult population is infected. In the United States, a total of 3,322 cases of acute hepatitis B were reported to CDC in 2018, but actual estimates were closer to 21,600.
Can hepatitis B survive outside the body?
The hepatitis B virus can survive outside the body and remains infectious for at least seven days. This is why proper cleaning of environmental surfaces potentially contaminated with hepatitis B virus is very important.
How is hepatitis B managed?
- Safe and effective vaccination
- Antiviral prophylaxis to prevent transmission from mother to child
- Adequate nutritional and fluid intake
- Safe injection practices
- Screening of all donated blood and blood products
- Oral treatments to suppress hepatitis B virus
How do I reduce my risk of hepatitis B?
- Get vaccinated. A very effective and safe vaccination for hepatitis B is available
- Don’t share needles
- Be in a long-term mutually monogamous relationship
- Use condoms correctly
- Avoid unregulated tattoos or body piercings
- Don’t share personal items that may have been in contact with infected blood (e.g. glucose monitors, razors)
