Ordering the MRT 135 Food Sensitivity Test
The MRT 135 Food Sensitivity Test from Oxford Biomedical helps identify immune reactions to 122 foods and 8 food chemicals, plus 5 new markers, by measuring changes in white blood cells. This test is often used by people experiencing symptoms like bloating, migraines, skin rashes, or digestive discomfort that may be linked to food sensitivities. Interestingly, you do not need to eat the foods before the test, making it suitable for those who have already eliminated certain foods or have immune system concerns.
Ordering this test provides:
- Detection of both common and less common food and chemical sensitivities
- Personalized results with a wallet-size card for easy reference while shopping
- No need to reintroduce foods before testing, reducing risk of symptom flare-ups
- Results that can guide targeted dietary changes for symptom relief
- Quick turnaround time, with results in 5-7 business days
Who Should Consider Food Sensitivity and Immune Response Testing
People who have tried multiple diets but still struggle with symptoms like headaches, fatigue, or skin issues may benefit from this test. For example, someone who has ongoing digestive problems despite avoiding common trigger foods could use this test to uncover hidden sensitivities and make more informed food choices.
Ordering may also be helpful in these situations:
- Recurring migraines that do not respond to standard treatments
- Unexplained skin rashes or hives that come and go
- Persistent joint pain without a clear cause
- Children with chronic stomach cramps or irregular bowel movements
- People who notice mood swings or brain fog after eating, which is less commonly linked to food sensitivities but can be significant
Pinpointing specific food and chemical triggers can help reduce symptoms like bloating, headaches, or skin reactions by guiding dietary changes based on your immune system’s response. Delaying this test may mean continued discomfort and missed opportunities to address symptoms with targeted nutrition changes.
How to Prepare for Food Reactivity and Chemical Additive Screening
Fasting is not required for the MRT 135 Food Sensitivity Test, but follow the instructions in your test kit for best results. Always go by any directions your doctor or healthcare provider gives you to make sure your sample is collected and shipped correctly.
