|21 days later - negative result
Apr 3, 2011
Can I take away any comfort from a negative hep B test 21 days after a potential exposure? If I want to be positive that I am clear how long should I wait for a 2nd test?
| Response from Dr. McGovern
Hepatitis B surface antigen will be detected in most patients by 4 weeks, although the outside range is 9 weeks. Thus, it is looking good for you, but you need further follow-up.
