A biomérieux investigation was conducted for a discrepant result (out-of-range-low) for candida albicans, atcc® 90028, associated with etest® voriconazole vo 32 ww f100.The investigation involved testing the etest® voriconazole vo 32 (lot 1003390050) customer strips, retained strip samples, and a different lot as reference, with 3 atcc stains (atcc 90028 - atcc 6258 - atcc 22019).The issue observed by the customer with the quality control strains was not reproduced.The customer stated that instead of streaking the plates, they "flow" the plates before they apply the etest®.Inoculation by floating is not the recommended procedure stated in the instructions for use (package insert) and it's necessary for antifungals to swab twice.The investigation concluded the etest® voriconazole vo 32 ww f100 is performing as intended.
