I am planning to undertake hiv early detection panel from Dr. Safe hands. This panel includes 2 tests:- hiv 4th generation elisa and hiv- 1 pcr rna. My exposure was with a used blade at a barberplace. It has been around 30 days since this last exposure. I do not have any other current sexual exposure (s). Is this panel test sufficient or do I need to go for hiv- 2 pcr rna as well? Also, does the hiv iv gen elisa look for both antigens and antibodies or just the antibodies?
