Test Code
Clinical Significance
Culture, Yeast with Limited Susceptibility -
This test is used to identify a clinically significant yeast and determine its susceptibility to a limited set of antifungal agents. This test may be helpful in optimizing treatment for recurrent yeast infections.
The susceptibility of a yeast isolate is measured by determining the minimum inhibitory concentration (MIC), which is the lowest drug concentration that prevents growth. An isolate can be categorized as susceptible, intermediate, susceptible-dose dependent, or resistant by comparing the MIC of an isolate to established clinical breakpoints [1]. MIC interpretations are based on ...
