Hepatitis B surface antigens can be found in your blood within several weeks after the infection starts. They are one of the earliest signs of a hepatitis B infection.HBV is 1 of 5 hepatitis viruses. The others are hepatitis A, C, D, and E. Most hepatitis infections are caused by these 5 viruses. HBV is spread through blood, seminal fluid, and vaginal secretions.
