Can You Tell Me Whether I Am HBSAG Positive Or Not ?
I do a test for hepatitis B The values are: 1,23 patient value, with a 1.0 cutoff value. This says I m infected? I m not vaccinated There are chances of false positives? What causes lead to a false positive? Need to know about margins of error and whether the value of 1,23, may appear to doubt it will be, because it close to the cutoff value Thank you very much

hi;
Get repeat test if you need to confirm as the values are close to normal value.False positive if it is could be an error in the testing kit as usually they do with ready kits .Tell them to do it again or get it done elsewhere.
thanks

Hello.welcome.HBsAg is present from 1 to 6 months after the exposure.HBeAg( e antigen) is present 1 to 3 months after acute illness and means high infectivity.Antibodies to HBcAg(anti-HBC) imply past infection..Persistence of HBsAg for more than 6 months defines carrier state( chronic infection) .Get your checked for these.Good luck.
