No they are not the same.
But are there any difference in accuracy?
Neither is conclusive at 28 days. A combo tests for HIV 1 and 2 antibodies. A DUO tests for HIV 1 and 2, antigen to HIV 1 and antibodies to both types.

This is combo and tests ab and ag also. I know that all tests are conclusive in 3 months. I just want to do this test at 28 days. Even i am going to new one in three months. Maybe i just could relax a bit more when i know this test accuracy in 28 days. Experts say it is 99.89% in 28 days. I just dont know what to believe anymore.
It's good result but you want conclusive results you have to do 3 months
everyone knows this by now
No they are not the same Combo an Duo are two different tests.
But this alere determine test both, antigens and antibody.
Yes it tests for HIV1 antigens and antibodies and HIV 2 and antibodies.
