There are no tests marketed or sold to give a conclusive negative test earlier than 3 months post exposure.
The DUO/COMBO looks for both p24 antigen and antibodies,The antibody test looks only for antibodies.P24 antigen is produced in high amounts in the first few weeks following infection,this is why it is such a useful test at around 3 to 4 weeks.
I am sorry, may i ask what is the difference between Duo/combo test and antibody test?
4weeks+ with a DUO/COMBO 3 Months with an antibody test and 6 Months and 9 Months are totally absurd.
There are two votes for 6 months is this correct
A DUO test which looks for antigen and antibodies is 6 weeks in Australia and 4 weeks in UK ...... the antibody test is 3 months, yet fairly accurate 2 months unless you have had chemo or a IV drug user or other underlying issues.
