Dear Dr,
I did the HIV combo test blood drawn vein after
23 days Combi PT ( Cobas)
31 days Combo Ag/Ab Abbott Alinity ci series
43 days Combi PT ( Cobas)
50 days Combo Ag/Ab ( Serum,CMIA)
All these result was negative and my exposure (Unprotected sex)
Are these results conclusive? Should I take another test
