The Lettuce IgG test is a laboratory examination that measures immunoglobulin G (IgG) antibodies against lettuce in a patient's serum, indicating an immune response to this food. A blood sample is required, collected in a red-top or serum gel tube, and processed to obtain serum. The serum is stable for up to 28 days refrigerated or 365 days frozen. The test uses a Fluorescent Enzyme Immunoassay (FEIA) method, providing standardized results. Clinically, it helps identify adverse reactions to lettuce, such as gastrointestinal symptoms or skin rashes, but does not confirm a food allergy. Results are reported in micrograms per milliliter, with values under 2.0 mcg/mL considered absent. The test's turnaround time is 3 to 7 business days. Cross-reactivity with other antigens can occur, necessitating careful interpretation. The test aids in developing dietary plans but should be supervised by healthcare professionals to avoid nutritional deficiencies. It is a Laboratory Developed Test (LDT) performed in CLIA-certified labs.

The Lettuce IgG test is designed to detect IgG antibodies against lettuce, indicating an immune response. Key points include:
- Specimen Requirements: Blood sample in red-top or serum gel tube; 0.5 mL serum needed.
- Specimen Stability: Refrigerate for 28 days; freeze for 365 days; ambient for 7 days.
- Methodology: Uses Fluorescent Enzyme Immunoassay (FEIA) for standardized results.
- Clinical Utility: Identifies potential adverse reactions to lettuce.
- Interpretation: Values <2.0 mcg/mL are undetectable; higher suggests immune response.
- Turnaround Time: 3 to 7 business days.
- Cross-Reactions: Possible with other antigens; interpret with clinical context.
The Lettuce IgG test is crucial for identifying individuals who may have an immune response to lettuce. This test is particularly useful in specific clinical situations where food-related complaints are suspected. Key points include:
- Specimen Requirements: A blood sample is needed, collected in a red-top or serum gel tube.
- Specimen Stability: Serum is stable refrigerated for 28 days or frozen for 365 days.
- Methodology: Uses Fluorescent Enzyme Immunoassay (FEIA) for analysis.
- Clinical Utility: Helps identify adverse reactions but doesn't confirm allergies.
- Interpretation: Results guide dietary changes, supervised by healthcare professionals.
Understanding test results is crucial for making informed health decisions. The Lettuce IgG test results are reported in micrograms per milliliter (mcg/mL). Here's how to interpret them:
- < 2.0 mcg/mL: Absent or undetectable levels of allergen-specific IgG antibodies.
- ≥ 2.0 mcg/mL: Indicates a potential immune response to lettuce.
It's important to note:
- A positive result suggests sensitization, not a confirmed allergy.
- Cross-reactivity with other antigens may occur.
- Consult healthcare professionals for personalized dietary advice and further evaluation.
