Quality control procedures of AST should be implemented in order to minimize the inaccuracy of dilution methods and lack of reproducibility when hydrophobic compounds such as ITC are tested. Reference method for broth dilution antifungal susceptibility testing of yeast, 3rd ed.

Development and validation of a high-performance liquid chromatographic assay for the determination of fluconazole in human whole blood using solid phase extraction. First indications of improved capability and capacity of public health microbiology laboratories in the European Union http: A multicenter study was conducted to assess the accuracy of the ISO standard and the serial 2-fold dilution procedures for antifungal susceptibility testing.

ITC is a weakly basic drug pKa ca. Evaluation of performance of antimicrobial susceptibility test devices.

Precision of fluconazole dilution series by dilution procedure and laboratory a. Projects and data submission Microtiter plates were prepared according to the ISO standard and by serial dilution procedures recommended for preparation of trays of both hydrophilic and hydrophobic drugs 9 The greatest discrepancy was observed for the lowest concentrations and for the dilutions prepared outside Spain and shipped for concentration determinations.

Comparisons between results obtained by the tray preparation method were done by using analysis of variance ANOVA. When there are no breakpoints? However, itraconazole trays showed a significant lack of reproducibility that was independent of which method was followed. Since the hydrophilic growth medium RPMI-G at pH 7 has been selected for testing in vitro antifungal susceptibility, it was important to describe the lack of proper solubility of this compound.

Prevalidation statistical design to assess analytical methods. Regarding serial 2-fold dilution procedures, better results were detected when FLC plates were prepared according to the hydrophilic rather than the hydrophobic way. Susceptibility testing of infectious agents and evaluation of performance of antimicrobial susceptibility testing devices.

Thus, serial dilution, which is attractive due to its simplicity, may be appropriate. Single-step extraction of fluconazole from plasma by ultra-filtration for the measurement of its free concentration by high performance liquid chromatography.
