Allergy Screen- Phadiatop (Adult & >5yr), ImmunoCAP

The Allergy Screen- Phadiatop (Adult & >5yr), ImmunoCAP is an allergy screening test that detects specific IgE antibodies in the blood, which are associated with allergic reactions. This test helps screen for a wide range of allergens that may cause allergic symptoms in adults and children over 5 years old. The ImmunoCAP technology is highly sensitive and specific, reducing the likelihood of false positives and negatives, making it a reliable tool for diagnosing allergies and guiding treatment.

An allergy occurs when the immune system mistakenly identifies a harmless substance (allergens) as harmful and produces an inappropriate response by producing antibodies called Immunoglobulin E (IgE). The Allergy Screen- Phadiatop (Adult & >5yr), ImmunoCAP is an allergy screening test that helps doctors identify whether an individual’s (above 5 years) symptoms may be due to a common airborne allergen such as dust, pollens, grasses, molds, mites, feathers, etc. It helps diagnose allergic rhinitis, asthma, atopic dermatitis, and other allergic conditions by identifying relevant allergens.

Your doctor may suggest the Allergy Screen- Phadiatop (Adult & >5yr), ImmunoCAP test if you have symptoms suggestive of allergic reactions such as sneezing, runny nose, hives, difficulty breathing, itching, etc. Additionally, the Phadiatop test may be ordered when an individual has a family history of allergies. The test also helps doctors distinguish atopic (IgE-mediated) from non-atopic (non-IgE-mediated) allergies and aids in deciding appropriate treatment. 

Allergic bronchial asthma and allergic rhinitis are the most common manifestations of atopy. Therefore, this test may also be advised for individuals with asthma to identify triggers that aggravate asthma symptoms. However, since this test is highly specific to inhalant allergens, it does not assess the sensitivity to food, drugs, or other substances.

A positive Phadiatop test indicates that the individual is sensitive to one or more common inhalant allergens, which can be further investigated through more specific allergy testing. A negative result indicates no sensitization to the tested allergens, though it does not rule out allergies to other substances not included in this test.

Generally, no special preparation is required for the Allergy Screen- Phadiatop (Adult & >5yr), ImmunoCAP test. However, inform your doctor about any medications (such as antihistamines) you are taking, as they might influence your test results.

Reference ranges may vary based on factors such as age, medical history, etc. Narrate your complete medical history, including any known allergies and symptoms that can impact test interpretations, to help the doctor correlate your laboratory and clinical findings and formulate a robust treatment plan.
