Salivary Antibodies

The Rice IgE test is a specialized diagnostic tool designed to detect IgE antibodies in an individual's serum, specifically targeting rice-related allergens. This in vitro test is crucial for diagnosing rice allergies, identifying the specific allergens responsible for allergic reactions, and confirming sensitization before starting immunotherapy. The test requires a serum specimen, collected in a serum gel or red-top tube, and employs a Fluorescence Enzyme Immunoassay (FEIA) method. This involves a series of steps, including specimen preparation, ImmunoCAP reaction, washing, enzyme addition, incubation, and fluorescence measurement. Results are interpreted based on fluorescence values, categorizing IgE levels from negative to extremely high, indicating the likelihood of allergic disease. Clinically, the Rice IgE test aids in diagnosing rice allergies, preparing for immunotherapy, investigating allergic reactions, and monitoring allergic disease progression. With a quick turnaround time and specific specimen requirements, it is an essential tool for managing rice-related allergies effectively.

Purpose of the test

The Rice IgE test is a diagnostic tool designed to detect IgE antibodies targeting rice allergens in serum. Its primary purpose is to diagnose rice allergies, identify specific allergens causing symptoms, and confirm sensitization before immunotherapy. The test uses a Fluorescence Enzyme Immunoassay (FEIA) method, involving:

- Specimen preparation and centrifugation
- ImmunoCAP reaction with allergens
- Washing and enzyme addition
- Incubation and fluorescence measurement

Results are categorized based on fluorescence values, aiding in allergy diagnosis and management. Practical considerations include specimen stability and turnaround time.

Who Should Get Tested

The salivary antibody test is a non-invasive, cost-effective method for detecting SARS-CoV-2 antibodies, ideal for populations where blood draws are challenging, such as children and the elderly. Key points include:

- Non-Invasive Collection: Saliva is easily obtainable, making it suitable for community surveillance.
- Antibody Detection: Identifies IgA and IgG antibodies, indicating current or past infections.
- Diagnostic Performance: While sensitivity is lower than serum tests, combining multiple tests improves accuracy.
- Mucosal Immunity: Highlights the role of local immune responses, especially in unvaccinated children.
- Applications: Useful for mass screening and home collection, enhancing participation in studies.

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 effective allergy management. The Rice IgE test measures IgE antibodies to identify rice allergies. Results are categorized by IgE levels:

- Negative: <0.10 kU/L
- Borderline: 0.10-0.34 kU/L
- Equivocal: 0.35-0.69 kU/L
- Positive: 0.70-3.49 kU/L
- Strongly Positive: 3.50-17.4 kU/L
- Very Strongly Positive: 17.5-49.9 kU/L
- Extremely Strongly Positive: 50.0-99.9 kU/L
- Extremely High: ≥100 kU/L

Higher levels suggest a greater likelihood of allergic disease. Understanding these results aids in diagnosis, treatment planning, and monitoring allergic conditions.
