it will get negative anyway because you will make antibodies anyway the point is how many antibodies, so you have to check for hbsab antibody titer to get above 10miu/ml not hbsag
i have read in some cases hbsag becomes positive due to the vaccine but it becomes negative after 21 to 28 days right ??
hbsag is very important for me cuz in my country I have to be hbsag negative to be accepted in some jobs
thank u
the vaccine is made of hbsag to simulate antibody hbsab, the hbsag from vaccine has no virus so it cannot make the disease and is a chemical made in labs, but when you make hbsag test you can detect the hhbsag from vaccine
on the other hand what is the utility of making hbsag test now since you are looking for protective antibody hbsab to be made very fast?they should be made in 4 weeks if you are among non responders, the other shots are ussually done to increase the antibody titter
if you want to know if the virus is there, but there is no need according to me, you can check also hbvdna pcr with sensitivity at least 5-10iu/ml, in my country all hospitals have this maybe because of law requiring these tests sensitivity, but old tests which are cheaper can be used if in your country there is no law to use the most sensitive, so ask for sensitivity before going to make the test
hbvdna pcr might be more sensitive than hbsag test if it gets down to 1iu/ml
i dont understand what do u mean by it can be positive bcuz of the vaccine
how do I know if am positive bcuz of the vaccine ??
does it turn to negative if it was positive bcuz of the vaccine ??
you just need to check hbsab antibodies, checking hbsag is useless plus can be positive because of the vaccine not the virus
