Order Allergy TestingAllergy testing is a diagnostic approach used to identify substances that trigger an immune response. Rather than measuring a single compound, it evaluates the presence and level of specific antibodies that the body produces when exposed to common allergens. The results help clarify which environmental or food-related triggers may be relevant to a person's symptoms.
About Allergy Testing in O'fallon
Allergy testing assesses how the immune system reacts to potential allergens by measuring immunoglobulin E (IgE) antibodies in the blood.
The test typically screens for IgE antibodies directed against a panel of common allergens, which may include pollens, dust mites, animal dander, mold spores, and certain foods. Each allergen is reported with a numerical value that reflects the concentration of specific IgE in the sample.
Results are usually categorized as negative, low, moderate, or high, though the exact thresholds can vary by laboratory and by the specific allergen. A positive result indicates sensitization, meaning the immune system has produced antibodies to that substance. It does not by itself confirm that the substance causes clinical symptoms.
Because sensitization and clinical allergy are not identical, results are interpreted alongside a person's history and physical findings. A healthcare provider can use the reported values to guide further evaluation or management decisions.
