Lime IgE

The Lime IgE test is a specialized diagnostic tool designed to identify allergies to lime by detecting specific IgE antibodies in a patient's serum. This test is crucial for healthcare providers aiming to diagnose lime allergies accurately and manage them effectively. By measuring the immune response to lime, the test helps confirm sensitization, which is vital before starting treatments like immunotherapy. The procedure involves collecting a blood sample, which is then analyzed using Fluorescence Enzyme Immunoassay (FEIA) to detect IgE antibodies. Results are categorized from negative to extremely high, indicating the likelihood of an allergic reaction. While the test is highly informative, it has limitations, such as potential false positives in patients with elevated IgE levels and its ineffectiveness in assessing residual sensitivity post-immunotherapy. Despite these limitations, the Lime IgE test remains a valuable tool for guiding treatment strategies and ensuring accurate allergy management when interpreted within the clinical context.

Purpose of the test

The Lime IgE test is a diagnostic tool for identifying lime allergies. It measures specific IgE antibodies in the serum to confirm sensitization and guide allergy management. Key steps include:

- Specimen Collection: Blood sample in a serum gel or red-top tube.
- Testing Methodology: Uses Fluorescence Enzyme Immunoassay (FEIA).
- Result Interpretation: Ranges from negative to extremely high IgE levels.

Results must be interpreted in clinical context, considering patient history and symptoms. Despite limitations, it aids in diagnosing and managing lime allergies effectively.

Who Should Get Tested

The Lime IgE test is crucial for diagnosing lime allergies. It identifies specific IgE antibodies, indicating an immune response to lime. Here's who should consider testing:

- Individuals with unexplained allergic reactions after lime exposure.
- Patients with a history of food allergies seeking specific allergen identification.
- Those considering immunotherapy for allergy management.

The test involves:

- Collecting a blood sample.
- Measuring IgE levels using Fluorescence Enzyme Immunoassay.

Results guide treatment decisions, but must be interpreted in clinical context, considering patient history and symptoms.

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 managing lime allergies effectively. The Lime IgE test measures specific IgE antibodies in the serum to assess allergic reactions. Here's a brief guide to interpreting the results:

- Negative: <0.10 kU/L, no detectable IgE antibodies.
- Borderline/Equivocal: 0.10-0.34 kU/L, possible sensitization.
- Positive: 0.70-3.49 kU/L, increased likelihood of allergy.
- Strongly Positive: 3.50-17.4 kU/L, high likelihood of allergy.
- Extremely High: ≥100 kU/L, severe allergic reaction risk.

Always consider clinical context for accurate diagnosis and management.
