Lamb IgE

The Lamb IgE test is a specialized diagnostic tool designed to detect IgE antibodies specific to lamb in the blood, which are indicative of an allergic response. IgE antibodies play a pivotal role in allergic reactions by triggering the release of histamine and other chemicals, leading to symptoms such as hives, itching, and anaphylaxis. This test is particularly valuable for individuals who experience adverse reactions after consuming lamb or being exposed to lamb products. The procedure involves collecting a serum sample, which is then analyzed using a Fluorescence Enzyme Immunoassay (FEIA) method. This method ensures high specificity and sensitivity in detecting lamb-specific IgE antibodies. Results are quantified in kU/L, helping healthcare providers assess the likelihood of an allergic reaction. The test is instrumental in diagnosing lamb allergies, identifying allergens, confirming sensitization, and guiding treatment strategies. With a typical turnaround time of 1 to 3 days, it offers timely insights for effective allergy management.

Purpose of the test

The Lamb IgE test is designed to identify IgE antibodies specific to lamb, crucial for diagnosing lamb allergies. It involves:

- Sample Collection: Blood is drawn, and serum is separated.
- Immunoassay: Serum is tested using ImmunoCAP with lamb allergen.
- Detection: Enzyme-labeled anti-IgE binds to IgE, producing a fluorescent signal.

Results are measured in kU/L, indicating allergy likelihood:

- Negative: No significant IgE detected.
- Positive: Varying levels indicate allergy severity.

This test aids in allergy diagnosis, allergen identification, and treatment planning.

Who Should Get Tested

The Lamb IgE test is essential for individuals who suspect an allergy to lamb. It measures IgE antibodies in the blood, which are crucial in allergic responses. Symptoms like hives, itching, or anaphylaxis after lamb exposure warrant testing. The procedure involves:

- Sample Collection: Blood is drawn, and serum is separated.
- Immunoassay: Serum is analyzed using ImmunoCAP technology.
- Measurement: Fluorescence indicates IgE levels.

Results guide diagnosis:

- Negative: No significant IgE detected.
- Positive: Varying levels indicate allergy likelihood.

This test aids in diagnosing lamb allergies, confirming sensitization, and guiding treatment.

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 essential for interpreting the Lamb IgE test outcomes. This test measures IgE antibodies specific to lamb, indicating potential allergic reactions. Here's a brief guide:

- Negative Result: No significant IgE detected; allergy unlikely but not ruled out.
- Borderline Result: 0.10-0.34 kU/L; clinical relevance unclear, needs specialist input.
- Low Positive: 0.35-0.69 kU/L; low likelihood of allergy.
- Moderate Positive: 0.70-3.49 kU/L; moderate likelihood.
- High Positive: 3.50-17.49 kU/L; high likelihood.
- Very High Positive: ≥17.50 kU/L; strong likelihood of allergy.

These results guide diagnosis and management of lamb allergies.
