description

HCV-RNA assessment during therapy with Direct-Acting Antiviral (DAA) regimens still relies on assays requiring blood collection and transport to a specialised laboratory, which may compromise linkage to care. GeneXpert-HCV Viral Load (GXHVL) (Cepheid) is a plasma-based assay used at point of care (POC) with a sensitivity of ≤10 IU/mL, and, results available within 2 hours. Fifty-nine consecutive HCV-patients ready for DAAs treatment were enrolled. HCV-RNA was simultaneously tested using Roche TaqMan RT-PCR (venous blood sample) and GXHVL (capillary blood collected by fingerstick), at baseline (BL), week 4 (W4) of therapy, end of therapy (EOT) and week 12 of follow-up (W12FU). Both assays demonstrated undetectable HCV-RNA in all patients at EOT and identified the single case of HCV-relapse at W12FU. GXHVL used as a point-of-care assay in the outpatient setting provides results fully comparable to the laboratory-based test. Its excellent performance and ease of use suggest its adoption in non-specialist settings where simplicity of care is paramount to implement HCV eradication campaigns.
