With the ALCAT test, you might want to list LEAP testing which has been found to be more accurate than ALCAT (ALCAT has a reproducibility rate of around 45% but LEAP's mRT test has a reproducibility rate of 92%).
Who says? The LEAP people? Because ALCAT tests for a marker that is the end result of all kinds of reactions whether or not the immune system is involved. What does LEAP test for?
It has been about 6 months since I researched the topic, but LEAP was found to be more accurate by a third party at the University of Miami (or there abouts). The LEAP test is 15 years newer, was developed by the same man who developed the ALCAT test and tests how much histamine the white blood cells release when in the presence of certain foods.
So it's only for actual allergies then. No other kinds of intolerance.
It is a blood test that measures food sensitivities and does not catch allergies or intolerances. It tests foods and food chemicals. I am sorry if I have been unclear in my other posts. I am feeling tired.
Here is from their own page:The Mediator Release Test (MRT)Q. Is MRT accurate?
A. MRT is the most accurate blood test available for food sensitivities. Scientific studies have
shown MRT to be 94.5% accurate in sensitivity and 91.8% accurate in specificity in detecting reactive foods.Q. What is the difference between MRT and other tests for food sensitivities?
A. The primary differences between MRT and other laboratory tests for food sensitivities are:
1. MRT measures reactions from lymphocytes, granulocytes, and platelets. Other cellular tests
are limited to either lymphocytes or granulocytes.
2. MRT is an endpoint test. This means MRT provides the most comprehensive information of reactive and non-reactive substances. Serum blood tests such as ELISA IgG and other types of IgG testing limit themselves to the kind of immunologic reaction they can measure. Scientific studies have shown that food sensitivities involve at least seven different possible triggering mechanisms that can cause immune cells to react and release chemical mediators. MRT measures the reaction of the cells that are affected by the specific triggering mechanisms. The other tests measure the individual triggering mechanism that may not actually cause mediator release.
3. MRT is a functional live cell analysis measuring actual reactions of one‚€™s immune cells. Serum tests measure static levels of antibodies in your blood assuming that that is the mechanism causing immune cells to react.
4. The LEAP Test is quantitative. It quantifies the degree of the reaction that the food has
caused, helping to identify dosage dependent reactions.Q. How does MRT work?
A. MRT measures changes in the liquids to solids ratio of one‚€™s blood after the blood has been
exposed and incubated with the test substance so that all reactions by one‚€™s immune cells can be
accounted for. This is done as an indicator that one‚€™s immune cells have released chemical mediators such as histamine. Significant reactions are broken into either Reactive (Red) or Moderately Reactive (Yellow) categories and insignificant reactions (Green) are placed in the Non-Reactive category. All measurements are made using the most accurate method of measurement (Ribbon technology) currently available.Q. I know that I am allergic to a particular food but MRT said I was not. Why?
A. MRT identifies foods and food substances involved in food sensitivities and is the most
comprehensive blood test for these types of reactions. If one knows of a particular food allergy, it may not show up on MRT because of the underlying immunologic mechanism triggering the reaction. Immediate food allergies, triggered by a particular type of antibody known as IgE, will not usually show up on MRT because they involve a different subset of immune cells than are measured by MRT. If one‚€™s ‚€œallergy‚€Ě is not really an allergy, but rather a food intolerance, that also will probably not show up on your MRT results because the symptoms are not triggered by an immune system reaction. In any case, if one knows a particular food does not agree with him or her the best thing to do is avoid it.
