Hepatitis B Surface Antibody

The Hepatitis B Surface Antibody Immunity, Quantitative test is a special check-up to see if a person has protection against Hepatitis B. Doctors use this test to find out if someone has enough defense in their blood against this virus. The Centers for Disease Control and Prevention (CDC) says that if you have 10 or more units (called mIU/mL) of this defense, then you are protected.
