Nail Fungus Testing: Is It Necessary Before Treatment?
Published: Apr 14, 2024
Before treating onychomycosis, testing can ensure that the right treatment is chosen. Learn why and how testing is done.
The Importance of Testing
Testing confirms the presence of a fungal infection and identifies the type of fungus. This is crucial because different fungi may require different treatments. Common tests include potassium hydroxide (KOH) preparation and fungal cultures.
Types of Tests Available
Tests such as KOH preparation, PAS stain, and PCR can confirm onychomycosis and identify the fungus. Fungal cultures are particularly helpful as they show active infection. Accurate diagnosis helps avoid unnecessary treatments and directs appropriate therapy.
Cost-Effectiveness of Testing
While testing adds cost, it can save money by preventing ineffective treatments. Studies suggest that immediate empirical treatment with medications like terbinafine can be cost-effective. However, the best approach may vary by location and available treatments.
