Food Sensitivity Testing
Specimen Type & Acceptability
7 days refrigerated.
Each food will be rated on a Class scale: normal reactivity to high reactivity. A higher than normal reactivity level can mean that there’s a possibility that certain foods can be giving you symptoms. Symptoms to food sensitivities can vary from serious life-threatening reactions to general discomfort involve skin, gastrointestinal tract, cardiovascular system and respiratory tract. This assay is ideal for determining if you have food sensitivities. Once food sensitivity is determined, and depending on the scale of reactivity, the specific food should be removed from your diet and you should make an appointment with your physician. Even though increasing ranges are reflective of increasing concentrations of allergen-specific IgE, these concentrations may not correlate with the degree of clinical response or skin testing results when challenged with a specific allergen. The correlation of allergy laboratory results with clinical history and in vivo reactivity to specific allergens is essential. Please note that this assay is not a food allergy test. Lactose intolerance, celiac disease and other conditions may not be determined with this assay. A negative test may not rule out clinical sensitivity or even anaphylaxis.
Let clot for 10-20 minutes. After the sample is fully clotted, centrifuge the sample. Verify complete separation of cells and serum and refrigerate.
Approximately 1 SST tube per 10 allergens.
