Beef IgE

The Beef IgG test is a laboratory examination that measures immunoglobulin G (IgG) antibodies specific to beef in a patient's serum. IgG antibodies are crucial for long-term immunity, and this test helps assess immune responses in individuals with potential food sensitivities or allergies to beef. A serum sample is required, collected in a red-top or serum gel tube, with a minimum volume of 0.5 mL. The sample is centrifuged, aliquoted, and refrigerated before submission. The test uses an Enzyme Immunoassay (FEIA) method to quantify beef-specific IgG antibodies. While the clinical utility of food-specific IgG tests is not fully established, they can guide dietary evaluations in patients with food-related complaints. Results are expressed in micrograms per milliliter, with values below 2.00 mcg/mL indicating undetectable levels of IgG. The test's turnaround time is 3 to 5 business days. It should be ordered by knowledgeable physicians and interpreted alongside clinical findings.

Purpose of the test

The Beef IgG test measures immunoglobulin G antibodies specific to beef in serum, aiding in assessing food sensitivities or allergies. Key points include:

- Purpose: Evaluates immune response to beef in symptomatic individuals.
- Specimen: Requires 0.5 mL serum, collected in a red-top or serum gel tube.
- Methodology: Uses Enzyme Immunoassay (FEIA) for quantification.
- Interpretation: Results in mcg/mL; values <2.00 mcg/mL indicate undetectable levels.
- Considerations: Physician guidance is crucial; results should align with clinical context.

Who Should Get Tested

The Beef IgG test measures IgG antibodies specific to beef, aiding in assessing food sensitivities. It's crucial for individuals with food-related symptoms. Key steps include:

- Blood Collection: Use a red-top or serum gel tube.
- Centrifugation: Separate serum from cells.
- Aliquoting: Transfer 0.5 mL serum to a vial.
- Storage: Refrigerate or freeze serum.

The test uses Enzyme Immunoassay to quantify IgG levels. Results guide dietary evaluations but don't confirm allergies. Physicians must interpret results alongside clinical data, considering further tests 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.

Interpreting Test Results

Understanding test results is crucial for interpreting the Beef IgG test effectively. Here’s a concise guide:

- Purpose: Evaluates immune response to beef, aiding in identifying potential food sensitivities.
- Specimen: Requires 0.5 mL serum, collected in a red-top or serum gel tube.
- Methodology: Utilizes Enzyme Immunoassay (FEIA) to measure IgG antibodies.
- Interpretation: Results under 2.00 mcg/mL suggest low sensitization; higher values indicate possible sensitization.
- Considerations: Not definitive for allergies; should be used alongside other diagnostic methods.
