Candida albicans and Candida glabrata, NAA
Use
Detect the presence of Candida albicans and Candida glabrata DNA in vaginal samples as an aid to the diagnosis of vulvovaginal candidiasis in symptomatic women
Special Instructions
Not provided.
Limitations
The test, while useful for detecting Candida albicans and Candida glabrata, has its limitations. It has not been cleared or approved by the FDA but is determined by Labcorp to meet performance standards. The test might not account for all strains of Candida or other possible causes of vaginitis, thereby limiting its diagnostic range. It is crucial for healthcare providers to integrate the test results with other clinical data for comprehensive diagnosis. Additionally, published data suggests that up to 65% of Candida glabrata cases may exhibit reduced susceptibility to fluconazole, which could affect treatment outcomes.
