A variety of samples may be suitable for fungal culture. Please contact the laboratory if you have questions regarding sampling. For skin and hair samples a KOH preparation will be evaluated and reported within 24 hours. For other sites wet microscopy is reported within 24 hours. Fungal culture may take up to four weeks and results are released as soon as any fungal growth can be reliably identified. Sensitivity is not included with the culture but can be added if required, at additional cost.
