Cat epithelium and dander IgE

Cat epithelium and dander IgE

The lab test for cat epithelium and dander IgE antibodies is a vital diagnostic tool for evaluating allergic responses to cat allergens. It begins with assessing IgE antibodies, which are crucial in allergic reactions, against cat dander and epithelium. The initial phase involves testing for IgE antibodies to total cat dander using a fluorescent enzyme immunoassay (FEIA). If IgE antibodies are detected, further testing identifies specific allergenic components like Fel d 1, Fel d 2, Fel d 4, and Fel d 7. Fel d 1 is the primary allergen, often causing significant allergic reactions. Results are categorized from negative to extremely strongly positive, indicating varying levels of sensitization. While positive results suggest sensitization, clinical correlation with symptoms is essential for accurate diagnosis. This test aids in confirming sensitization, tailoring treatment strategies, and managing cat allergies effectively, despite its limitations in excluding all potential allergic responses.

Purpose of the test

The lab test for cat epithelium and dander IgE antibodies is a vital diagnostic tool for assessing immune responses to cat allergens. It begins with analyzing IgE antibodies to cat epithelium, indicating allergen recognition. Initial testing uses fluorescent enzyme immunoassay (FEIA) to detect IgE antibodies to total cat dander. If present, further testing identifies specific allergens like Fel d 1, Fel d 2, Fel d 4, and Fel d 7. Results are categorized as:

- Negative: <0.10 kU/L
- Borderline: 0.10-0.34 kU/L
- Positive: 0.70-3.49 kU/L

This test aids in diagnosing and managing cat allergies.

Who Should Get Tested

The lab test for cat epithelium and dander IgE is essential for diagnosing cat allergies, affecting up to 20% of the population. It identifies specific allergens causing symptoms, aiding in allergy management. The test uses Fluorescent Enzyme Immunoassay (FEIA) to detect IgE antibodies in serum. Key steps include:

- Sample Collection: Serum is collected and refrigerated.
- Specimen Preparation: Serum is centrifuged and transferred for testing.
- Testing Process: Serum reacts with allergens; fluorescence indicates IgE levels.

Results range from Class 0 (negative) to Class 6 (strongly positive). Interpretation requires clinical correlation.

Blood Test Preparation Guidelines

Time of day

It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.

Fasting

It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.

Stay hydrated

Drinking water prior to testing can help with sample collection.

Other factors

Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.

Medications and supplements:

Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.

Biotin supplements:

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.

Interpreting Test Results

Understanding test results for cat epithelium and dander IgE antibodies is essential for diagnosing cat allergies. This test evaluates the immune response to cat allergens by measuring IgE antibody levels. Key points include:

- Negative Results: IgE < 0.10 kU/L, indicating no sensitization.
- Borderline Results: IgE 0.10-0.34 kU/L, suggesting possible sensitization.
- Positive Results: IgE 0.70-3.49 kU/L, indicating sensitization.
- Strongly Positive Results: IgE > 3.50 kU/L, indicating high sensitization.

These results guide allergy management and treatment strategies.
