I am not a doctor. Please do not test for HbsAg status if you received your HBV vaccine recently(within the previous two weeks). Because the HBV vaccine is the HBsAg itself, it may cause you to have a false positive HBsAg.
I would suggest you also test:
1. HBsAb - a value of > 10 iu/L indicates you are protected.
2. HBcAb - A positive value indicates you had HBV infection before your HBV vaccination. If that is the case, your doctor may suggest you also measure your hbvdna , to rule out occult HBV infection(negative HBsAg, but hbvdna not zero).  Don't be alarmed by this possibility which is very low and its clinical significance is not yet fully clear.
