How are nail clippings tested for onychomycosis?
For information about the SORT evidence rating system, go to https://www.aafp.org/afpsort. When preparing a nail specimen to test for onychomycosis, the nail should be cleaned with 70% isopropyl alcohol, then samples of the subungual debris and eight to 10 nail clippings should be obtained.
What kind of test is used to diagnose onychomycosis?
Accurate diagnosis involves physical and microscopic examination and culture. Histologic evaluation using periodic acid–Schiff staining increases sensitivity for detecting infection.
How to treat a separated nail with onycholysis?
Treatment includes trimming away the separated nail, cleaning the nail bed, and applying a topical antibiotic. 4 If the infection is severe, an oral antibiotic may be prescribed.
Can you use pathpas to diagnose onychomycosis?
Further study is needed to determine if sensitivity may be enhanced by combining PATHPAS with cultures obtained by several collection methods (clipping, curettage, and shaving). Such combinations may serve as sensitive and efficient strategies for diagnosing onychomycosis.
What are the signs and symptoms of onycholysis?
Symptoms. Depending on the cause of onycholysis, the nail may have collected thickened skin underneath the edge of its nail plate, and the nail plate may have a deformed shape with pits or indentations in the nail surface, a bent nail edge or coarse thickening of the nail.

Can a PCR be used to diagnose onychomycosis?
Although more expensive, PCR has become a more common technique to confirm the diagnosis of onychomycosis, especially if cultures are negative or a definitive diagnosis is required ( 1, 2, 3 ). Histopathologic examination of PAS–stained nail clippings and subungual debris may also be helpful.
