Viral Load correlation between DBS and plasma matched samples at different storage temperatures. The VL was assessed by Cobas Monitor Amplicor, and the values were transformed to Log₁₀. VL values for plasma samples from ten different patients (sample ID) stored at -70 degree C (P), and paired blood spots samples stored at 4 degree C (D 4), 25 degree C (D 25), 37 degree C (D 37), and -20 degree C (D-20) for up to 7 days, and removed to -20 degree C until analysis.
