Cat + Allergen Components
Reflex testing for cat allergen with allergen component identification (exclusive at СDL OLIMP).
If you or your child experience sneezing, runny nose, itchy eyes, cough, nasal congestion, rash, or asthma attacks after contact with a cat, this may indicate an allergy.
The allergy is caused not by the fur itself, but by specific proteins found in the animal’s skin, saliva, and secretions.
To accurately confirm the allergy and assess its characteristics, a modern test with identification of individual cat allergen components is performed.
What does the test show ?
The analysis detects the presence of IgE antibodies to the main cat allergen components:
Fel d 1 (e94)
- The main and most significant cat allergen. Produced by sebaceous and salivary glands, it easily spreads in the environment and remains on surfaces for a long time. Most commonly associated with allergic rhinitis and bronchial asthma.
Fel d 2 (e220)
- Serum albumin may cause cross-reactive allergic reactions with other animals (such as dogs and horses) and sometimes with meat. Identification of this component is important for detecting broader sensitization
How is the test performed ?
- A blood sample is taken from a vein once.
- First, total IgE to cat allergen is measured.
- If a reaction is detected, an additional test for specific allergen components (Fel d 1, Fel d 2) is automatically performed.
- If there is no reaction to cat allergen, additional testing is not carried out.
- No repeat blood sampling is required.
Why is it important to identify allergen components?
Component diagnostics helps to:
- confirm a true cat allergy;
- assess the risk of developing respiratory symptoms and asthma;
- detect possible cross-reactivity with other animals;
- clarify the nature of sensitization;
- help the doctor choose the correct treatment and monitoring strategy.
Why ImmunoCAP ?
The test is performed using the ImmunoCAP system - the international standard for laboratory allergy diagnostics.
Advantages:
- high accuracy and reproducibility of results;
- detection of even low levels of IgE antibodies;
- safe - no direct contact with the allergen;
- suitable for children and adults;
- no need to stop taking antihistamines.
