Details about Mycology/Skin Scrapings by PCR
What is the Mycology / Skin Scrapings by PCR test?
The Mycology / Skin Scrapings by PCR test uses polymerase chain reaction (PCR) technology to detect fungal genetic material from skin scrapings, nail clippings, or hair samples. It identifies dermatophytes, yeasts, and other fungi responsible for superficial fungal infections.
PCR testing is significantly more sensitive than traditional microscopy and culture. It can detect fungal infection even when organisms are present in very low numbers or when previous treatments have partially suppressed growth.
This test is used for accurate diagnosis when fungal infection is suspected but difficult to confirm.
Why do I need a Mycology / Skin Scrapings PCR test?
Fungal skin, nail, and scalp infections can mimic other dermatological conditions and may not respond to treatment if misdiagnosed.
You may need this test if you have:
-
Persistent or recurrent skin rashes
-
Itchy, scaly, or cracked skin
-
Thickened, discoloured, or brittle nails
-
Nail separation from the nail bed
-
Scalp scaling or hair loss
-
Skin lesions not responding to treatment
-
Suspected fungal infection before starting antifungal therapy
Accurate identification helps guide appropriate treatment and avoids unnecessary or ineffective therapies.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
