Reverse T3

The Red Kidney Bean IgE test is a specialized diagnostic tool designed to identify specific IgE antibodies in a patient's serum, indicating an allergic reaction to red kidney beans. Utilizing the ImmunoCAP Fluorescence Enzyme Immunoassay (FEIA) method, the test involves binding the red kidney bean allergen to a cellulosic polymer, which interacts with IgE antibodies in the patient's serum. After a series of washes and the addition of an enzyme-labeled anti-IgE antibody, the fluorescence of the eluate is measured to determine the IgE levels. This test is essential for diagnosing red kidney bean allergies and understanding the immune response to this allergen. It requires a serum specimen and provides results within 1-2 business days. The test results are classified into different classes based on IgE levels, ranging from negative to very high positive. While red kidney beans are not common allergens, they can cause reactions in sensitized individuals, with some cross-reactivity noted with other legumes.

Purpose of the test

The Red Kidney Bean IgE test is designed to identify specific IgE antibodies in serum, indicating an allergy to red kidney beans. This test is essential for diagnosing such allergies and pinpointing the allergen causing symptoms.

- Methodology: Utilizes ImmunoCAP FEIA, linking allergens to a polymer, reacting with serum IgE.
- Clinical Utility: Standard for allergy diagnosis, indicating immune response to allergens.
- Specimen Requirements: Serum in red-top or gel-barrier tube, 0.2 mL minimum.
- Interpretation: IgE levels classified from negative to very high positive.
- Practical Considerations: Conducted weekdays, results in 1-2 days.

Who Should Get Tested

Reverse T3 (rT3) is a metabolically inactive thyroid hormone produced from thyroxine (T4). Its levels can rise in certain conditions, affecting thyroid function assessment. Key points include:

- Production: rT3 is formed by deiodination of T4, especially during stress or illness.
- Clinical Significance: High rT3 levels are seen in conditions like starvation, severe trauma, and hepatic dysfunction.
- Diagnostic Utility: Useful in identifying sick euthyroid syndrome, distinguishing it from hypothyroidism.
- Test Procedure: Involves blood sampling and LC-MS/MS analysis.
- Interpretation: Elevated rT3 may indicate stress or metabolic imbalances.

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 managing allergies effectively. The Red Kidney Bean IgE test identifies specific IgE antibodies, indicating an allergic reaction to red kidney beans. Here's a quick guide to interpreting your results:

- Class 0: <0.10 kU/L - Negative
- Class 0/1: 0.10-0.34 kU/L - Equivocal/Borderline
- Class 1: 0.35-0.69 kU/L - Low Positive
- Class 2: 0.70-3.49 kU/L - Moderate Positive
- Class 3: 3.50-17.49 kU/L - High Positive
- Class 4-6: >17.50 kU/L - Very High Positive

Understanding these classes helps in diagnosing and managing your allergy effectively.
