Comparison of lyophilized and frozen microtiter systems for routine MIC testing in the clinical laboratory.
Frozen microtiter plates (Micro-Media Systems, Inc.) and lyophilized microtiter plates (Sensititre--Seward Laboratory/Gibco Diagnostics) were used to perform simultaneous MIC determinations. Specimens were obtained from blood, urine and other clinical isolates. The authors found that there was good correspondence of results with the frozen microtiter MIC plates and the lyophilized microtiter MIC plates. After careful evaluation, the authors conclude that the lyophilized product is as stable and as reproducible as the frozen product. The lyophilized product is more easily and conveniently stored, has a longer shelf life and is more flexible.
