Onion IgE
The Onion IgG test is a specialized laboratory examination designed to detect immunoglobulin G (IgG) antibodies targeting onion allergens in a patient's serum. Utilizing an Enzyme Immunoassay (EIA) method, this test quantifies IgG concentrations by measuring antibody binding to onion allergens. Blood samples are collected in red-top or serum gel tubes, requiring a minimum of 0.5 mL of serum, which is then refrigerated for transport. While the test provides insights into potential onion sensitivities, it does not confirm food allergies, as IgG presence indicates sensitization rather than an allergic reaction. Results are reported in micrograms per milliliter, with values under 2.00 mcg/mL considered undetectable. The test is not FDA-approved for diagnostic use and should be interpreted by knowledgeable healthcare professionals. Turnaround time ranges from 3 to 8 business days. Despite its limitations, the Onion IgG test can aid in managing suspected food sensitivities when used appropriately.

The Onion IgG test is a specialized lab examination to measure IgG antibodies targeting onion allergens. It helps identify potential sensitivities, not definitive allergies. Key points include:
- Methodology: Uses Enzyme Immunoassay (EIA) to quantify IgG.
- Specimen Collection: Requires 0.5 mL serum, stored appropriately.
- Clinical Utility: Indicates sensitization, not a confirmed allergy.
- Interpretation: Values under 2.00 mcg/mL are typically undetectable.
- Considerations: Not FDA-approved; used by informed physicians.
- Turnaround: 3-8 business days.
Understanding these aspects ensures effective use in managing food sensitivities.
The Onion IgE test is essential for diagnosing onion allergies by detecting specific IgE antibodies in the serum. It is particularly useful for:
- Identifying allergens causing allergic reactions.
- Confirming sensitization before immunotherapy.
- Investigating allergic reactions to various allergens.
The test uses Fluorescence Enzyme Immunoassay (FEIA) methodology, involving:
- Blood sample collection.
- Allergen preparation with ImmunoCAP.
- Reaction and measurement of IgE levels.
Results are interpreted based on fluorescence values, indicating allergy severity. This test aids in managing allergies effectively, guiding treatment decisions, and ensuring accurate diagnosis.
Understanding test results is crucial for effectively managing potential food sensitivities. The Onion IgG test measures specific IgG antibodies to onion allergens, providing insights into possible sensitivities. Here’s a brief guide:
- Result Interpretation: Values under 2.00 mcg/mL suggest absent or undetectable IgG levels. Higher values indicate sensitization, not necessarily a clinical allergy.
- Clinical Context: Results should be interpreted by healthcare professionals familiar with the test’s limitations.
- Utility: Not FDA-approved for diagnostics, it aids in managing suspected food sensitivities.
- Turnaround: Typically 3-8 business days.
Understanding these aspects ensures informed decisions in dietary management.
