(A) Stability of HIV-1 RNA in whole blood stored at room temperature. Results are expressed as mean percentages of baseline copy numbers for EDTA (top curve), ACD (middle curve), and heparinized (bottom curve) plasma. Horizontal bars represent SD. (B) Stability of HIV-1 RNA in whole blood stored at room temperature in comparison to mean baseline (≤1 h) EDTA-treated specimens. Results are expressed as mean percentages of EDTA baseline copy numbers for EDTA (top curve), ACD (middle curve), and heparinized (bottom curve) plasma. Horizontal bars represent SD.
