Description
Why It’s Done:
Doctors may recommend this test to:
• Diagnose fungal infections of the skin, nails, lungs, mouth, genital area, blood, or internal organs
• Identify the specific fungus responsible for symptoms such as rashes, persistent cough, fever, or nail discoloration
• Guide antifungal treatment by determining the type of fungus and its drug sensitivity
• Monitor chronic or recurring fungal infections, especially in immunocompromised individuals (e.g., those with HIV, cancer, or on immunosuppressive therapy)
Preparation:
• Sample Type: The preparation depends on the sample site:
o Skin/Nail/Hair: Avoid using creams, lotions, or antifungal powders for 24–48 hours before the test
o Sputum: You may be asked to rinse your mouth and cough deeply to provide a morning sample
o Urine or Vaginal Swab: A clean-catch or midstream urine sample may be required; avoid douching before a vaginal swab
o Blood or Tissue: No specific preparation; may require a simple blood draw or a biopsy
• Fasting: Not usually required
• Medications: Inform your doctor if you’re using antifungal medications, as they may interfere with the test results
