Hepatitis B transmission and detection
Hi,
Need your input. I have a case which puzzles me at the moment. Im a first year medical student and dont exposure yet on diagnosis and diseases so please bear with me if my questions look basic to you. My brother had his medical check up last July 3, 2012 and Sept 6, 2012. Both resulted to clear findings. However, his employer once again conducted a medical on Oct 1st and he was identified to have " hepatitis B surface antigen positive." The first two(2) medical tests were conducted by a different clinic.
My questions are:
- Is it technically possible that he will have both medical tests on July and Sept cleared then his Oct 1st is positive?
- According to my research, transmission of Hep B virus is via sexual contact and blood to blood contact. My brother does not donate blood or engage in any activity involving blood to blood contact or needle sharing. His wife does not have Hep B. Given that the identified risk factors are not applicable to him, how else can he could have gotten the virus?
Will appreciate your prompt help.
Thank you and best regards,

Testing for HBsAg is not carried out in routine medical checkup. I am some what puzzled as to why the same tests would be carried out 3 times in such a short space of time.
In any case, it is usual to try to determine whether the infection is acute or chronic when a person is tested positive for HBsAg for the first time with no previous history of Hepatitis B infection.

I dont have the complete medical files yet but i assume yes. Otherwise, there will be no basis for clearing him on his previous medical tests.
This is the information from CDC:
http://www.cdc.gov/hepatitis/hbv/hbvfaq.htm
HBsAg will be detected in an infected person’s blood an average of 4 weeks (range: 1–9 weeks) after exposure to the virus.
Did your brother have HBsAg status tested during his two medical checkups?
