Simultaneous quantification of voriconazole and posaconazole in human plasma by high-performance liquid chromatography with ultra-violet detection. 207776 control procedures of AST should be implemented in order to minimize the inaccuracy of dilution methods and lack of sio when hydrophobic compounds such as ITC are tested.

Open in a separate window. Calibration and validation – archive In order to determine and compare the accuracy of each method described for microdilution, two consecutive HPLC determinations of the azole concentration were calculated from different wells of trays prepared according ISO recommendations, serial dilutions for hydrophobic drugs, and serial dilutions for hydrophilic compounds. However, itraconazole trays showed a significant lack of reproducibility that was independent of which method was followed.

Where clinical data is lacking! Development and validation of a high-performance liquid chromatographic assay for the determination of fluconazole in human whole blood using solid phase extraction.

Fluconazole trays can be accurately prepared by following ISO and serial dilution schemes. Sitemap Search close sitemap. 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 Furthermore, previous studies have demonstrated a ieo higher interlaboratory variation in MIC results for quality control strains for itraconazole than for flucytosine and fluconazole 6 oso 8.

According to those oso and the ISO recommendations, the 2-fold dilutions of compounds should be performed in a multistep, rather complex, and time-consuming fashion, avoiding serial dilutions in order to prevent the risk of a systematic error being induced, for instance, by an imprecise pipette 9. Susceptibility testing of yeasts Considering only data for dilution series prepared in Spain, no systematic difference was detected between ISO dilution and serial dilution. Reference method for testing the in vitro activity of antimicrobial agents against rapidly growing anaerobic bacteria involved in infectious diseases.

Since the hydrophilic growth medium RPMI-G at 2776 7 has been selected for testing in vitro antifungal susceptibility, it was important to describe the lack of proper solubility of this compound.

Abstract A multicenter study was conducted to assess the accuracy of the ISO standard and the serial 2-fold dilution procedures for antifungal susceptibility testing.
