    Recalling Organisation: Roche Diagnostics (NZ) Ltd, 15 Rakino Way, Mt Wellington, AUCKLAND 1644
  • Reason
    In extremely rare circumstances, the algorithm for the cobas® hiv-1 and hbv tests for use on the cobas® 4800 system may inappropriately call an extraordinarily high viral load sample as negative (i.E., false negative result). this situation occurs when the positive pcr growth curve for the target has a ct value below the ct minimum for the test, resulting in the kinetic algorithm calling the curve negative instead of invalid.
