Overview of the Nail Clippings Test
The Nail Clippings test is a mycology investigation of nail material, used to determine whether persistent nail changes are caused by fungal infection.
The test assesses 1 microbiology biomarker: Nail Clippings Mycology.
Fungal nail infection is known medically as onychomycosis.
It can affect fingernails or toenails and is commonly caused by dermatophyte fungi.
Yeasts and non-dermatophyte moulds can also occasionally be involved.
Typical nail changes include thickening, discolouration, brittleness, crumbling or separation of the nail from the nail bed.
However, these appearances are not specific to infection.
Psoriasis, trauma, eczema and several other nail disorders can resemble fungal disease.
Laboratory confirmation is therefore useful before committing to prolonged oral antifungal treatment.
The laboratory can examine nail material by microscopy and fungal culture.
Microscopy may identify fungal structures directly.
Culture attempts to grow viable fungi and can sometimes establish the organism involved.
Culture takes considerably longer because dermatophytes and other fungi can grow slowly.
This explains the extended turnaround compared with routine blood tests.
Previous antifungal treatment can reduce the chance of detecting viable fungi.
The sample should therefore be collected from an active abnormal area of nail where possible.
A negative result does not absolutely exclude fungal infection if the specimen contains insufficient affected material.
What Does the Nail Clippings Test Check?
The test examines nail material for evidence of fungal infection. This test measures 1 specialist biomarker.
Nail Clippings Mycology
Examines nail material using mycological laboratory methods to detect dermatophytes, yeasts or other fungi associated with onychomycosis.
Who May Benefit From the Nail Clippings Test?
Nail mycology is useful where fungal infection is suspected but needs confirmation.
People with persistently thickened nails - Fungal infection is one possible cause.
People with yellow, white or brown nail discolouration - Onychomycosis can alter nail colour.
People with brittle or crumbling nails - Fungal infection can damage the nail plate.
People with nail lifting from the nail bed - Onycholysis can occur with fungal disease but also has other causes.
People with recurrent suspected fungal nail infection - Laboratory confirmation can help guide management.
People considering long-term oral antifungal treatment - Confirmation is particularly useful before systemic therapy.
People whose previous antifungal treatment has failed - Testing can establish whether fungus is actually present.
People with nail changes that could represent psoriasis or trauma - Mycology can help separate fungal from non-fungal causes.
How to Prepare
A good-quality specimen improves the chance of identifying fungal infection.
Very small superficial clippings may be less informative than material taken from the active diseased portion of the nail.
Symptoms and Reasons to Consider the Nail Clippings Test
Fungal nail infection usually develops gradually.
Thickened nail plates - Fungal growth can alter nail structure.
Yellow or white discolouration - Changes in colour are common.
Brittle or crumbly nails - The nail can become fragile and irregular.
Debris beneath the nail - Subungual material can accumulate.
Nail separation - The nail plate can lift away from the underlying nail bed.
Repeated athlete's foot with toenail changes - Dermatophyte infection can spread between skin and nails.
Persistent nail changes despite treatment - Laboratory confirmation can clarify whether fungal infection remains present.
Painful swelling, spreading redness, pus or significant inflammation around the nail can indicate bacterial infection or another complication requiring clinical assessment.
Nail appearance alone cannot reliably distinguish fungal infection from other nail disorders.

When Will I Receive My Results?
The current London Blood Tests page lists a turnaround of approximately 3 weeks after laboratory receipt.
Fungal cultures require longer incubation than routine microbiology because fungi can grow slowly.
A final negative culture generally cannot be reported until the appropriate incubation period has passed.
Understanding Your Results
A negative result means fungal elements or growth were not detected in the submitted specimen.
This makes fungal infection less likely but does not absolutely exclude it.
Poor sample quality or recent antifungal treatment can reduce detection.
A positive result confirms laboratory evidence of fungal infection.
The laboratory may identify a dermatophyte, yeast or mould depending on the organism and method.
The significance of non-dermatophyte mould growth sometimes requires careful clinical interpretation because environmental contamination can occur.
Treatment decisions depend on the organism, number of nails affected, severity and individual medical history.
Why Book With London Blood Tests?
London Blood Tests provides private nail mycology testing for confirmation of suspected fungal infection.
Confirms whether fungus is present - Laboratory testing helps distinguish infection from other nail disorders.
Can prevent unnecessary antifungal treatment - Not every thick or discoloured nail is fungal.
Uses direct nail material - The laboratory investigates the affected tissue itself.
Can identify different fungal groups - Dermatophytes, yeasts and moulds can be assessed.
Useful before prolonged oral treatment - Confirmation is particularly important when systemic medication is being considered.
Suitable for fingernails and toenails - Either type of nail can be sampled.
Specialist fungal culture - Adequate incubation allows slow-growing organisms to be detected.
Clear pricing - The Nail Clippings test costs £142.
