An optimized analytical method of fluconazole in human plasma by high-performance liquid chromatography with ultraviolet detection and its application to a bioequivalence study. Susceptibility testing of pathogenic fungi with itraconazole: Susceptibility testing of yeasts The presence and concentration of FLC or ITC in each well was determined by comparing the chromatographic signal peak area, retention time, and a UV spectral pattern of between and nm from the sample and from standard solutions.

Abstract A multicenter study was conducted to assess the accuracy 207766 the ISO standard isso the serial 2-fold dilution procedures for antifungal susceptibility testing. Furthermore, previous studies have demonstrated a much higher interlaboratory variation in MIC results for quality control strains for itraconazole than for flucytosine and fluconazole 6 – 8.

However, itraconazole trays showed a significant lack of reproducibility that was independent of which method was followed. This azole compound can only be ionized and solubilized in water at a very low pH, and also earlier studies have indicated that poor solubilization can have a significant influence on generated MIC values Thus, ITC data obtained from trays prepared by the Inn Austria participant were excluded from the analysis since tray wrappings showed evidence of defrosting and spillage; also, concentrations of dilutions prepared in Denmark were unacceptably different from the target concentrations.
