Ordering the 190 IgG Food Allergy Test with Candida & Yeast | Dried Blood Spot
This test helps identify delayed food reactions and sensitivities to 190 foods, as well as immune responses to Candida and yeast, using a simple dried blood spot sample. It is especially useful for those experiencing ongoing digestive discomfort, skin issues, headaches, or unexplained fatigue that may be linked to food sensitivities or yeast overgrowth. Interestingly, research shows that IgG-mediated food reactions can contribute to symptoms that appear hours or even days after eating certain foods, making them difficult to pinpoint without testing.
Ordering this test provides specific benefits:
- Pinpoints delayed food reactions that may not be detected by standard allergy tests
- Assesses immune response to Candida and yeast, which can be linked to digestive and skin symptoms
- Uses a convenient dried blood spot collection, eliminating the need for a blood draw at a lab
- Includes a comprehensive panel covering foods from Western, Asian, and Mediterranean diets
- Supports targeted dietary changes based on measurable immune responses
Who Should Consider Food Sensitivity and Yeast Testing
People who have tried multiple diets but still experience symptoms like bloating, rashes, or headaches may benefit from this test. For example, someone who avoids common allergens but still struggles with digestive issues and fatigue could use this test to uncover hidden food sensitivities or yeast-related triggers.
Ordering may also be helpful in these situations:
- Persistent eczema or skin rashes that do not improve with topical treatments
- Recurring sinus congestion or headaches after eating certain foods
- Unexplained joint pain or inflammation that fluctuates with diet
- Chronic constipation or diarrhea without a clear cause
- Difficulty losing weight despite healthy eating habits, which can sometimes be linked to food sensitivities
Testing for delayed food and yeast reactions can help clarify which foods or yeast exposures are contributing to symptoms, allowing for more targeted dietary changes and symptom tracking. Delaying this test may result in continued exposure to hidden triggers, making it harder to identify patterns and achieve symptom relief.
Preparing for Food Allergy and Yeast Antibody Testing
Fasting is not required for this dried blood spot test, so you can eat and drink as usual before collecting your sample. Always follow any instructions or sample collection tips provided by your doctor or healthcare practitioner to ensure your sample is collected correctly and processed without delay.
