There are no tests marketed or sold to give a conclusive negative test earlier than 3 months.
then why would some of the best ID doctors in the world including doctor EWH and HANSFIELD say they are conclusive at 28 days?
All tests are conclusive at 3 months post exposure.
Is 3 month conlusive for antibodie only test, or also for a combi test which looks for antigen and antibodies?
or is 28 days conclusive for combi test?
But then why do doctors in the forum say 28 days is conclusive for a combi test?
An antibody test at 8 weeks is unlikely to turn positive. 3 months (or 12 weeks) is still a conclusive test, but try to relax.
