Food Intolerance also known as Food sensitivity is difficulty in digesting certain foods & having an unpleasant physical reaction in the form of symptoms like tummy pain, bloating, acidity, upset stomach within few hours of eating specific food. Food Intolerance is an adverse reaction to a food, likely to originate in the gastrointestinal system, usually caused by a limited ability or an inability to digest or absorb certain foods or their components. Common foods that cause Food Intolerance are Milk, casein, shell fish, Chocolates, etc. The symptoms can be intermittent or last longer. Its difficult to identify which food your body is struggling to deal with. Hence, getting a test done which includes all common food items of different category is beneficial to identify your food raising intolerance in your body. 3 common e.g of food ingredients causing food intolerance are Lactose Casein & gluten. FI is avoidable by keeping a food diary & eating in small amounts.
It is an adverse reaction by the body to certain food items. The most common foods that cause intolerance reaction are MILK, CHOCOLATE, WHEAT, SPICES, NUTS, and FRUITS. Well-known food intolerance reactions are Lactose intolerance and gluten intolerance. The test measures the antibody IgG in your blood which is a memory antibody circulating in your body.
No. You cannot do a food intolerance test. In the Food Intolerance test, IgG is measured from your blood sample. This Ab is raised in your body in response to the food item which your body is not tolerating to digest. So in the absence of the trigger, the IgG level in your blood may go down or insufficient to get detected by the test and you will get a false negative report. So you should include such food items in your daily diet or at least every other day for at least a month or 2. However, if the food concerned is causing extreme reactions/ symptoms, do not re-introduce it to your diet & inform the lab.
You need to give a minimum of 3 ml of a blood sample for both tests.
You should not avoid any food item min 4-5 weeks before the test. Or please inform the lab if you have restricted any food.
It measures the IgG antibody in your blood sample for each food item included in the test. Also, it gives an overview of the IgG profile (Low, intermediate, or high IgG level) for all 13 food categories.
It is not required unless you want to understand if precautionary measures have really worked & Antibody levels have really come in the normal range.
Food intolerance will give you a result in the form of a semi-quantitative value of your antibody against the intolerant food item (s) or allergen (s). It may be possible that you are allergic/ intolerant to one or more antigens.
Food Intolerance measures IgG Antibody in your body from a small amount of blood sample very sensitively.
Please see the indications of testing & you can also consult with your physician.
In one working day, you will get the test result in a soft copy.
Yes Sample need not be a fasting blood sample. Only a sample immediately after heavy food is avoided.
Food Intolerance test ranges 1000-12000/-
The Allergen test can measure as low as 0.3 Ku / l OF iGe Ab from your sample whereas FI test measures as low as 5 ug/ml for all food extracts.
False-positive test results may occur due to the cross-reactivity of the tested antigen with epitopes of other antigens. Antigenic epitopes may be lost during the production of food extracts, which may lead to false negative results. IgG antibodies to food antigens that occur only during industrial preparation, food preparation, or digestion may not be detectable in the patient sample.
