Allergen, Fungi and Molds, Candida albicans
Also known as: CAN RAST
Use
This test is used to detect the presence of allergen-specific IgE antibodies in the blood serum for Candida albicans. It helps in the identification of patients with allergic reactivity to this specific allergen, and it is especially useful for diagnosing mold allergies caused by Candida albicans. The test quantitatively measures the concentration of IgE specific to this allergen using a fluorescent enzyme immunoassay method, which is sensitive for detecting low levels of allergen-specific IgE.
Special Instructions
The specimen should be separated from cells as soon as possible, ideally within 2 hours of collection, to ensure accuracy. The separated serum must be properly transferred to an ARUP Standard Transport Tube for analysis. Patients should avoid multiple encounters during the specimen collection process to ensure the integrity of the test results.
Limitations
This test measures the concentration of Candida albicans-specific IgE, but the results do not always correlate with clinical symptoms. IgE levels in the 0.10-0.34 kU/L range need careful consideration by a specialist, as their clinical relevance is uncertain. Low IgE levels may not rule out the allergy or anaphylaxis, and high levels might not directly relate to the severity of clinical symptoms. The allergen test should be combined with patient history and in vivo testing for a precise diagnosis.
