Candida albicans in skin wheal (qualitative, 50 µg) – Immunofluorescence probe
This test checks for the presence of *Candida albicans*—a type of yeast—that may cause skin infections, including ringworm or fungal skin rashes. It uses a small sample of your skin wheal (a raised, red area from a scratch or irritation) to detect yeast cells.
["A positive result may indicate a fungal skin infection needing treatment, while a negative result suggests no active yeast presence in this sample."]

How the Test Works
A healthcare provider will gently scrape a small area of your skin wheal (a raised, irritated spot) to collect cells. These cells are then tested using a fluorescent dye that binds to *Candida albicans* yeast if present. The test is qualitative, meaning it only tells you whether yeast is detected, not how much.
What to Expect Before the Test
No special preparation is needed. You may shower or wash the area lightly before the test, but avoid heavy lotions or creams. If you have open wounds or severe irritation, let your provider know before testing.
What to Expect During the Test
The test is quick and painless. A healthcare provider will clean the wheal, apply a small amount of numbing cream (if needed), and gently scrape a sample. You may feel a slight pinch, but it lasts only a moment. The sample is then sent to the lab for analysis.
Possible Results and Next Steps
A positive result means *Candida albicans* yeast was found in your skin sample. This could indicate a fungal skin infection (e.g., tinea corporis, or ringworm). Your provider may recommend antifungal treatments, such as creams, oral medications, or further testing. A negative result means no yeast was detected in this sample, but other causes of irritation could still be present.
