Guest guest Posted June 6, 2001 Report Share Posted June 6, 2001 My Family Physician's Assistant, who does not know a lot about this whole process but has been very honest with me from the start and very willing to read whatever I bring her, said she will order whatever test I want her to. Which of these tests are useless on a GFCF diet? Which of these tests are more important than others. Thanks in advance. I went to the Great Plains Laboratory and found the following: 1. Organic Acids Test - Virtually all specimens from children with autism or PDD have one or more abnormal Organic Acid compounds, due to abnormal levels of yeast and other gastrointestinal bacteria. These compounds can affect, among other things, neurological functioning, vitamin utilization, energy level, intestinal wall integrity, hormone utilization, and muscle function. In addition to identification of excessive levels of GI yeast or bacteria, the test also reveals nutritional or antioxidant deficiencies, inborn errors of metabolism, amino or fatty acid problems, exposure to solvent toxins, indications of possible diabetic conditions, deficiencies of B or C vitamins, and unusual levels of neurotransmitters. 2. Yeast Culture and Sensitivity - This test should be done in combination with the organic acid test to get the most accurate reading for yeast and bacteria overgrowth. By doing both of these tests you will have all the evidence your doctor needs to help you treat this problem. The urine organic acid test is the most accurate measure of yeast, which can sometimes be overlooked in the stool test. Yeast can sometimes attach to the intestinal lining and will not be eliminated in the stool. In some cases, the sections of stool where the yeast is present are not the sections that are collected and sent in to be analyzed. Generally, however, the stool test is an accurate test. The greatest benefit of the stool test is the sensitivity portion of the test, which will tell you which antifungal agents your intestinal yeast will respond best to. 3. Food Allergy - The impact of food allergies on behavior can be astounding, and cravings are very often, for the same foods that cause allergic reactions. And, those foods may play a role in abnormal levels of GI organisms. We have two panels available; one that tests for 92 foods, and another that tests for 10 of the most common foods people are allergic to. We recommend doing one of these two panels. It is best to have the full panel done. However, the 10 food panel is good for those who have limited resources, or for those who do not want to wait until the yeast problem is under control to see what food allergies they have. 4. Immune Deficiency Panel - Numerous papers document inadequate immune functioning in this many populations, increasing the vulnerability to bacterial/viral/fungal infections. In particular, yeast is well-documented as suppressing the immune system. So, if there is an excessive yeast population, it increases the likelihood of an inadequate immune response, in turn, increasing the probability of more infections and more yeast. Our panel is designed specifically for this patient population; for instance, levels of zinc, and specific immune proteins like IgA and subclasses of IgG, are often inadequate. 5. Peptide Testing for Milk and Wheat - In most cases people that have food allergies to milk and wheat, also have problems with peptides from milk and wheat interacting with their brain and causing an opiate-like affect. However, there are some people that may not show a food allergy to milk or wheat, but have the peptide problem and vice versa so it is a good idea to have both the peptide and food allergy testing done. If you prefer to have only one of the tests run, we recommend the food allergy testing since it can be assumed that the majority of people who have food allergies to casein and gluten also have the peptide problem. The peptide test is also a urine test and thus may be more convenient. 6. Inhalants (Comprehensive or Basic) IgE - Particularly useful when allergies to inhalants, such as dust, molds, and pollens are suspected; blood tests have improved considerably over the years, and are especially helpful with individuals who would have difficulty complying with skin testing or have skin rashes; to save time; or for very young children. May also be considerably cheaper than skin testing. 7. Amino Acids - Helpful in assessing causes and treatments for lethargy, muscle weakness, vitamin deficiency, protein intolerance, vomiting, kidney stones, inborn errors of metabolism, and seizures. Since many of these symptoms are caused, or worsened, by elevated levels of GI yeast/bacteria, we recommend that Amino Acid testing follow Organic Acid testing and treatment (if indicated) for GI organisms. The Organic Acid test includes some indicators of inborn errors of metabolism. 8. Vitamin Profile - Helpful in identifying inadequate diet, malabsorption, poor compliance, gastric mucosal status, and causes of anemia and DNA synthesis deficiency. The 20 vitamin profile is useful if Carnitine levels are needed. Vitamin testing can be very important in children with diarrhea, loose stools, or undigested food in the stool. Children who are extremely picky eaters may also benefit from this test since their nutrient intake may be imbalanced. Recently some researchers have found that in some cases Vitamin A deficiency can cause vision problems in autism, and is thus another good reason to have the vitamin levels checked. 9. Essential Fatty Acids - Deficiencies of essential fatty acids are associated with hair loss, dry or peeling skin, diarrhea, eczema, fatigue, aggression, dry brittle hair, eating disorders, excessive thirst, gallstones, growth impairment, immune deficiency, hyperactivity, and impaired wound healing. Essential fatty acids can be deficient due to inadequate dietary intake, diarrhea, loose stools, inadequate production of pancreatic enzymes, or inadequate production or secretion of bile or bile salts. The pattern usually observed in children with autism is deficiency of omega-3 fatty acids, especially alpha-linolenic acid with elevations of arachidonic acid and trans fatty acids. Arachidonic acid is extremely important since it is converted to the regulatory substances called prostaglandins. Grains and meats from grain-fed animals may be very high in arachidonic acid. Trans fatty acids are unnatural fatty acids produced by hydrogenating unsaturated fatty acids. Trans fatty acids may be especially harmful when alpha- linolenic acid is deficient. Trans fatty acids may affect neuronal fluidity by virtue of different dimensions compared to cis fatty acids. Trans fatty acids are high in foods like French fries, potato chips, margarine, cookies, and cake. 10. Metals (blood, hair or urine) - Hair is useful for the detection of toxic metals such as lead, aluminum, mercury, and cadmium. Lead may be found in dirt near roads and is commonly present in paint from older houses. Children with pica or who eat paint chips may develop toxic lead levels. Cadmium is used in batteries, steel-belted tires, and plastics. The clear plastics used to cover foods may be a source of cadmium and it is also found in cigarette smoke. Mercury is used in batteries, dental amalgam, vacuum pumps, valves, and seals. High amounts of mercury from the dental fillings of the cremated deceased have caused contamination of the surrounding neighborhoods. Arsenic is high in seafood and may also be found in animals fed arsenic in their feed. Arsenic is also present in wood preservatives, fungicides, herbicides, corrosion inhibitors, and in lead and copper alloys. Children with autism may respond favorably to removal of toxic metals. Children with autism as a group also have low values of essential elements like calcium, potassium, zinc, and magnesium. Treatment of heavy metal exposure usually involves the removal of the heavy metal source and/or treatment with chelating agents. Quote Link to comment Share on other sites More sharing options...
