Special Info

The Fungal Screen is designed to detect rapidly growing yeast. For slower growing yeasts and molds, order a Fungal Culture (order code FCUL). If culture is positive, limited identification is performed from nonsterile sites. Full identification is performed from sterile sites with an additional charge. Identification CPT codes that may apply include: 87106, 87107, 87153. Antimicrobial susceptibilities are performed on sterile sites, and CPT code 87186 would apply.

Clinical Info

The Fungal Screen rules out fungal infection with rapidly growing yeasts.
