Cadmium - Blood

The Cabbage IgG test is a laboratory examination that measures Immunoglobulin G (IgG) antibodies against cabbage in a patient's serum. IgG antibodies are crucial for long-term immunity, and this test helps identify sensitization to cabbage, which may cause gastrointestinal or systemic symptoms. While the clinical utility of food-specific IgG tests is not fully established, they can be useful in evaluating food-related complaints, particularly when considering dietary elimination and challenge strategies. The test is performed using an Enzyme Immunoassay (FEIA) and requires a blood sample, preferably serum, collected in a red-top or serum gel tube. Proper specimen handling and storage are essential for accurate results, with serum stability maintained for varying durations depending on storage conditions. Results are typically available within 3 to 7 business days and are reported in micrograms per milliliter. A positive result indicates sensitization but does not confirm a food allergy, necessitating careful interpretation alongside clinical evaluation.

Purpose of the test

The Cabbage IgG test measures IgG antibodies against cabbage in serum, indicating sensitization. While not definitive for allergies, it aids in evaluating food-related symptoms. Key points include:

- Clinical Utility: Useful for food intolerance evaluation.
- Procedure: Uses Enzyme Immunoassay (FEIA).
- Specimen Requirements: Serum from red-top or serum gel tube.
- Specimen Stability: Room temperature (7 days), refrigerated (28 days), frozen (365 days).
- Turnaround Time: 3-7 business days.
- Interpretation: Positive results suggest sensitization, not allergy.
- Special Instructions: Follow collection and storage guidelines.

Who Should Get Tested

In determining who should undergo the Cabbage IgG test, several factors are considered:

- Symptom Presentation: Patients experiencing gastrointestinal issues like bloating or systemic symptoms such as fatigue may benefit from testing.
- Dietary Evaluation: Those undergoing diet elimination and challenge processes might need this test to identify potential cabbage sensitivities.
- Clinical Context: A positive result should be interpreted alongside the patient's medical history and symptoms, as it indicates sensitization, not a confirmed allergy.
- Healthcare Guidance: Providers use this test to guide dietary interventions, ensuring it aligns with broader diagnostic evaluations.

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 making informed decisions. Here's a concise guide:

- Positive Result: Indicates IgG antibodies against cabbage, suggesting sensitization.
- Interpretation: A positive result doesn't confirm a food allergy. Consider clinical symptoms and history.
- Clinical Context: Use results alongside other diagnostic methods for comprehensive evaluation.
- Limitations: IgG presence alone isn't definitive for allergies; it's a marker of exposure.
- Consultation: Discuss results with healthcare providers for tailored dietary advice and management.
