Persistence of human immunodeficiency virus type 1 subtype B DNA in dried-blood samples on FTA filter paper.
The stability of human immunodeficiency virus type 1 (HIV-1) DNA in whole blood collected on filter paper (FTA Card) was evaluated. After >4 years of storage at room temperature in the dark our qualitative assay detected virus at a rate similar to that of our initial test (58 of 60, 97%; P = 0.16), suggesting long-term HIV-1 DNA stability.
