Onychodystrophy Testing

Histopathology + PCR = The Complete Picture

Various nail disorders appear identical and clinical examination alone may not be enough.

Definitive Diagnosis

Definitive Diagnosis

Laboratory testing identifies the underlying cause of nail dystrophy – infectious, non-infectious, neoplastic processes, and trauma

Histopathology Microscope

Histopathology

Microscopic evaluation of a specimen to determine infectious or non-infectious pathologies including traumatic, inflammatory or neoplastic processes.

Periodic Acid–Schiff (PAS): Identifies non-degenerated fungal elements

Grocott Methenamine Silver (GMS): Identifies degenerated fungal elements

Fontana-Masson (FM): Identifies pigmented saprophytes and melanin pigment which may be associated with a melanocytic neoplasm

PCR DNA

PCR

Molecular analysis of a specimen to determine if DNA of an infectious organism is present.

Onychodystrophy PCR Test: Identifies genus and species of most common fungi (dermatophytes, saprophytes, and yeasts) as well as the bacteria, pseudomonas aeruginosa, that cause nail dystrophy

PCR with Terbinafine Resistance Reflex: When positive for T. rubrum or T. mentagrophytes, detects mutations associated with terbinafine resistance
