This study evaluated a new testing method combining DNA analysis (PCR) with traditional microscopy and culture to diagnose fungal skin, hair, and nail infections. The PCR method detects the infection quickly and accurately, identifying the specific fungus causing the problem within days rather than weeks. The study of over 4,400 samples found that Trichophyton rubrum was the most common cause of fungal infections, and the combined testing approach was 98.5% accurate while reducing unnecessary lab work.
