VITEK 2 AST-Yeast Voriconazole is designed for antifungal susceptibility testing of Candida species and is intended for use with the VITEK 2 and VITEK 2 Compact Systems as a laboratory aid in the determination of in vitro susceptibility to antifungal agents. VITEK 2 AST-Yeast Voriconazole is a quantitative test. Voriconazole has been shown to be active against most strains of the microorganisms listed below, according to the FDA label for this antifungal.
Active in vitro and in clinical infections: Candida krusei Candida parapsilosis Candida tropicalis
The VITEK 2 Fungal Susceptibility Card is intended for use with the VITEK 2 Systems in clinical laboratories as an in vitro test to determine the susceptibility of clinically significant yeasts to antifungal agents when used as instructed.
Device Description
The principle of the VITEK® 2 AST cards is based on the microdilution minimum inhibitory concentration (MIC) technique. The VITEK® 2 AST card is essentially a miniaturized, abbreviated and automated version of the doubling dilution technique. Each VITEK® 2 AST card contains 64 wells. A control well which only contains microbiological culture media is resident on all cards. The remaining wells contain premeasured portions of a specific antibiotic combined with culture media. The bacterial or yeast isolate to be tested is diluted to a standardized concentration with 0.45-0.5% saline before being used to rehydrate the antimicrobial medium within the card. The VITEK® 2 System automatically fills, seals and places the card into the incubator/reader. The VITEK® 2 Compact has a manual filling, sealing and loading operation. The VITEK® 2 Systems monitor the growth of each well in the card over a defined period of time. At the completion of the incubation cycle, a report is generated that contains the MIC value along with the interpretive category result for each antibiotic contained on the card.
VITEK® 2 AST-YS Voriconazole has the following concentrations in the card: 0.03125, 0.125, 0.25, 1, and 2 (equivalent standard method concentration by efficacy in ug/mL).
