Test Parameters & Specifications
Sample Stability
- Sample received in inappropriate transport medium
- Sample not labeled correctly
- Sample with visible contamination or degradation
Understanding Your Results
Detected
Presence of Malassezia RNA, consistent with active infection. Clinical correlation and antifungal therapy may be required.
Not Detected
No Malassezia RNA detected. Other causes of skin lesions should be considered.
Consult a dermatologist or infectious disease specialist if you have persistent skin symptoms, or if the test result is positive, to discuss treatment options.
Limitations
- ⚠Qualitative test does not quantify fungal load
- ⚠May not differentiate between colonization and active infection
- ⚠Requires careful sample handling to preserve RNA integrity
Risks & Considerations
- ●Minimal risk of bleeding or infection at collection site
- ●No significant side effects
Interfering Factors
- ●Use of topical antifungal agents prior to sample collection may reduce fungal load and cause false negatives
- ●Improper sample collection or storage may degrade RNA
- ●Contamination from normal skin flora may lead to false positives
