Amplification of the gp120 V3 sequence from the 200 whole blood samples stored at +4°C (WB4) and at −20°C (WB20) using a first singlicate plus second triplicate testing approach

Sample type	Positive with first singlicate test	Positive with second triplicate test	Negative with both first singlicate and second triplicate test	Overall % of positive cases
WB4	155	26	19	90.5
WB20	152	27	21	89.5
