Sensitivity of the near full-length assay tested on HCV positive clinical samples. The success rate of amplifying near-full length genomes in relation to viral load is shown for 122 samples. Eighty-six of the 95 HCV positive samples with a viral load greater than 14,800 IU/ml were successfully amplified (90.5 % success rate). All 27 samples with a viral load below 14,800 IU/ml failed to amplify, however, 10 of these samples were retested following concentration by ultracentrifugation, of which three (30 %) were successfully amplified (hollow circles)
