If you want to check whether you have hepatitis B, you only need to go for the hepatitis B five tests. The hepatitis B five tests include five results, and for a simple look, you can just look at the first hepatitis B surface antigen. If the surface antigen is positive, you are a hepatitis B patient. If the surface antigen is negative, you are not currently a hepatitis B patient. However, sometimes this result alone is not completely certain, so it is necessary to use the other items in the five hepatitis B tests to determine if you are a hepatitis B patient. If you want to spend less money and even less money to see if you are hepatitis B, you can check only the surface antigen of hepatitis B. However, in many hospitals, this test cannot be done alone, and some patients with insidious hepatitis B are not detected by this test alone.
