Dog dander IgG

Dog dander IgG

The Dog Epithelium IgE test is a specialized laboratory assay used to detect IgE antibodies in a patient's serum, indicating an allergic response to dog epithelium, which includes skin and mucous membranes. This test is essential for diagnosing allergies to dog dander, a common allergen that can trigger allergic reactions and anaphylaxis in sensitive individuals. Clinically, it helps confirm an allergy diagnosis, define allergen specificity, investigate allergic reactions, and confirm sensitization before immunotherapy. The test results categorize IgE levels into classes, indicating the severity of sensitization, from normal to extremely high. A blood sample is required, and proper specimen handling is crucial for accurate results. Reflex testing may be conducted for specific dog dander components if initial results are positive. While the test is a valuable diagnostic tool, results must be correlated with clinical history and symptoms, as positive IgE results indicate sensitization but not necessarily an active allergy.

Purpose of the test

The Dog Epithelium IgE test is a diagnostic tool for measuring IgE antibodies in serum, indicating allergic responses to dog epithelium. It serves several clinical purposes:

- Diagnosing Allergies: Confirms allergy to dog dander by measuring specific IgE levels.
- Defining Allergen Specificity: Identifies the allergen causing symptoms, aiding in tailored treatment.
- Investigating Allergic Reactions: Assesses reactions to other allergens, broadening allergy profiles.
- Confirming Sensitization: Ensures effective immunotherapy by confirming sensitization.

Results are categorized by IgE levels, requiring clinical correlation for accurate diagnosis and management.

Who Should Get Tested

The Dog Dander IgG test is a specialized assay measuring IgG antibodies to dog dander in serum. Its clinical utility is limited, primarily used when other diagnostics are inconclusive. The procedure involves collecting blood, separating serum, and using an enzyme immunoassay to quantify IgG levels. Results are available in 3 business days. Key considerations include:

- Specimen Type: Serum
- Volume: 0.5 mL
- Assay Range: 2.0 to 200 mcg/mL

Clinical interpretation requires caution, correlating results with patient history. Practical applications include allergy diagnosis and monitoring sensitization.

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 is crucial for effective allergy management. The Dog Epithelium IgE test measures IgE antibodies to identify allergies to dog dander. Here's how to interpret the results:

- Class 0: Normal IgE levels (<0.35 kU/L) suggest no allergy.
- Class 1: Low IgE (0.35-0.69 kU/L) indicates mild sensitization.
- Class 2: Moderate IgE (0.70-3.49 kU/L) shows stronger sensitization.
- Class 3-6: High to extremely high IgE (3.50 kU/L and above) indicates significant sensitization.

Always correlate results with clinical history for accurate diagnosis.
