Background and aims: The Cepheid, GeneXpert provides hepatitis C virus (HCV) PCR results <90 minutes. A major limitation is the need to load finger prick samples <15 minutes, as patients must be co-located with the machine. Venous blood collected into EDTA tubes can be stored for up to 72 hours at 2-8°C prior to processing. In this project finger-prick blood collected into EDTA capillary tubes and processed >15 minutes after collection was compared with venepuncture (gold standard) and dried-blood spot testing (DBST) to facilitate testing remote from the machine (e.g. prison clinics on different wings remote from a centrally located machine) but still delivering rapid turn-around times with testing in close proximity to the point of need.
