Doctor:How can I help you?
User:Good morning Dr XXXXXXX
User:I am a bit confused with the Hep B testing
User:also, Hep C
User:let me tel u the background
Doctor:Please proceed.
User:i had a risky exposure on march 03rd 2013
User:after 2month, HbsAg is -ve, 3months HCV is -ve, and 4months HbsAg is -ive
User:its reached 5months now
User:do I need any retest?
User:if so, which kind of test do I need to take?
Doctor:Just like HIV, window period of Hepatitis b and c is between 2 weeks to 3 months.
Doctor:Most cases of active Hepatitis infection is diagnosed on tests beyond 3 months past the last exposure.
User:ok.. did I underwent the correct test, HbsAg?
Doctor:So, the negative reports of Hepatitis on 4th month is good enough.
User:ok.. HbsAg is the test or is there something else?
User:i heard HB antibodies -- something
Doctor:HbsAg which is antigen detection is positive in those having chronic infection. We require other tests such as anti hepatitis c antibody test as well as anti Hbs antibody tests
Doctor:to completely rule out acute infection
Doctor:if the exposure is risky and suspected to carry a possible risk of Hepatitis infection.
User:i have taken HCV antibodies test after 3 months - negative
User:coming to the risk,
User:it was a condom breakage at the time of ejaculation. and prior to that, i had completely protected sex with multiple partners
User:could you please let me know my risk level sir
Doctor:As you would know the condom break episode makes the sexual intercourse unprotected.
Doctor:The risks involved with hepatitis depend on the duration of unprotected intercourse and the infection state of your partner.
User:im not sure about the infection state of the partner, but the duration of intercourse is less than 20 seconds
Doctor:This duration is a fairly short one. But if the partner's infection state is unknown and the partner is known to have multiple other sexual partners, then the risk cannot be neglected.
Doctor:In this situation, 4 months is good enough time to see HbsAg positive, if you had hepatitis B.
Doctor:Since it is negative, we can consider yourself to be free from Hepatitis B.
User:ok.. so, is it not required to go for Hep B antibodies test?
Doctor:However some doctors including me would prefer to see other reports such as anti hepatitis c antibody as well as anti hepatitis s antibody
Doctor:to safely exclude hepatitis b following that exposure.
Doctor: XXXXXXX if it is not very clear, I would like to speak to you and clarify.
User:sure sir
User:can we speak over phone
Doctor:Let me know if that is ok with you, I can call you and clarify it.
User:please arrange a call sir, we can discuuss
Doctor:Can you confirm your phone number?
Doctor:Hope your doubts are cleared.
Doctor:Bye for now.
