Detects: Acute Hepatitis-B infection.
Hepatitis B is a virus that can be sexually transmitted and attacks the liver. Bodily fluids that carry the highest concentrations of the virus include blood, semen, and vaginal secretions. A surface antigen screening is an easy way to detect recent, acute, infection. Donors are encouraged to wait at least 4-6 weeks before testing for a more reliable result, but the antigens can be detected as early as 2 weeks out. This test is common in general STD screenings, and is also required for MMA/UFC pre-fight testing.
