Horse Dander IgE

Horse Dander IgE

The Horse Dander IgG test is a diagnostic tool designed to measure immunoglobulin G (IgG) antibodies specific to horse dander in the blood. IgG antibodies play a vital role in the immune system, primarily indicating past exposure to allergens rather than current sensitization. The test's primary purpose is to assess exposure to horse dander and monitor immune response changes over time. However, its clinical utility in diagnosing allergies is limited compared to IgE tests, which are more directly linked to allergic reactions. The procedure involves collecting a blood sample, separating the serum, and analyzing it using an enzyme immunoassay. Results are typically available within three business days and reported in micrograms per milliliter. While the test provides valuable information about past exposure, it is not FDA-approved for diagnostic use and is best utilized by specialists aware of its limitations. For accurate allergy diagnosis, healthcare providers generally rely on IgE tests.

Purpose of the test

The Horse Dander IgG test measures IgG antibodies specific to horse dander, indicating past exposure rather than current sensitization. Key points include:

- Purpose: Assesses exposure to horse dander; limited allergy diagnostic utility.
- Procedure: Blood sample collection, serum separation, enzyme immunoassay analysis.
- Specimen Requirements: 0.5 mL serum, refrigerated if not immediately analyzed.
- Turnaround Time: Typically 3 business days.
- Interpretation: High IgG suggests past exposure, not current allergy.
- Limitations: Not FDA-approved for diagnostics; IgE tests preferred for allergies.

Who Should Get Tested

The Horse Dander IgE test is essential for diagnosing allergies to horse dander. It identifies specific IgE antibodies in patients experiencing symptoms like sneezing or itchy eyes after horse exposure. The test uses the Fluorescence Enzyme Immunoassay method, involving:

- Sample collection and preparation
- Immunoassay with the ImmunoCAP system
- Enzyme-labeled anti-IgE addition
- Incubation and fluorescence measurement

Clinical utilities include:

- Diagnosing horse dander allergies
- Identifying allergens
- Confirming sensitization

Results guide allergy management, with reflex testing for specific components if needed.

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.
