The Hepatitis B Surface Antigen Home Blood Test Kit screens for hepatitis B surface antigen (HBsAg) to monitor active hepatitis B virus infection markers through a simple finger-prick blood sample for wellness and screening purposes. The test provides screening of current HBV infection markers, enabling early follow-up to support liver health and help prevent viral transmission to others.

Particularly valuable for individuals with potential exposure through healthcare work, international travel to endemic regions, unprotected sexual contact, needle sharing, or household contact with infected persons. Early monitoring of active hepatitis B infection markers allows for prompt medical evaluation, treatment discussions, and implementation of measures to help prevent spread to family members and close contacts. Levels outside the reference range may require further clinical investigation with your GP.

All-inclusive price: Includes home collection kit, laboratory analysis, and pre-paid return shipping. No additional clinic fees are required for this finger-prick test.

Laboratory Requirement – Sample Timing: Take this test at least 4 weeks after any potential hepatitis B exposure to ensure valid screening results. Earlier testing may not screen recent infections due to the window period. Laboratory Requirement – No Fasting Required: This test does not require fasting. You can eat and drink normally before collecting your sample. Factors Affecting Results: While rare, there is a small chance of false-positive or false-negative results. If you have concerns about your results, please consult with your healthcare provider. Test Scope: This test is specifically designed for people who think they may have an active current infection of hepatitis B. It does not screen for antibodies and will not indicate whether you have immunity to hepatitis B. Further Investigation: If your results indicate positive for hepatitis B surface antigen, we recommend discussing them with your GP for clinical interpretation and further testing. This screening test monitors infection markers and does not provide a clinical diagnosis.

The hepatitis B surface antigen (HBsAg) is a protein on the surface of the hepatitis B virus, present in the blood during a hepatitis B virus infection. Screening for this surface antigen helps monitor acute and chronic HBV infection markers. A positive surface antigen result suggests the virus is present and that the individual may be infectious. HBsAg can be screened in the blood on average around four weeks after exposure to HBV. The hepatitis B virus is a DNA virus that consists of a core particle and a surrounding envelope, with the envelope containing the surface antigen. This test is specifically designed for people who think they may have an active current infection of hepatitis B, though it does not screen for antibodies and will not indicate whether you have immunity to hepatitis B. Levels outside the reference range may require further clinical investigation with your GP.
