Hello, I'd like to ask the results of two-and-a-half hepatitis B examination!

OD value is a reference value; S/CO value is the test result. Generally speaking, the S/CO value is negative when it is less than the OD value, and positive when it is greater than the OD value.

Surface antibody: the OD value was 0.227, and the S/CO value was 2. 162, which was positive. The test results show that you have antibodies in your body, which is good. Hepatitis B surface antibody is the only protective antibody, and its positive indicates that you are immune to hepatitis B virus now. So you are healthy and not infected with hepatitis B. Your antibody titer is a little weak now, so you should get a shot of hepatitis B vaccine.
