Order Allergy TestingAllergy testing is a broad category of laboratory methods used to identify immune responses to specific substances. Rather than a single test, it encompasses several approaches that measure different parts of the immune system, most commonly immunoglobulin E (IgE) and, in some cases, immunoglobulin G (IgG). The results help characterize sensitization patterns and are interpreted alongside a person's history and physical findings.
About Allergy Testing in Walnut
Allergy testing measures immune proteins that react to particular allergens, such as pollens, foods, animal danders, molds, insect venoms, and latex.
The most frequently ordered format is specific IgE testing, which quantifies antibody levels directed against individual allergens. A related approach, total IgE, measures the overall amount of IgE in the blood without identifying a specific trigger. Both are blood-based and report numeric concentrations, often in kilounits per liter (kU/L).
Another category is IgG-based testing, which detects immunoglobulin G antibodies to foods or other substances. IgG is the most abundant antibody class and can reflect past exposure rather than a true allergic reaction. Because of this, IgG results are generally not used to diagnose classic allergy, and their clinical meaning differs substantially from IgE testing.
Results are reported as numeric values with reference ranges or as graded categories, depending on the laboratory. A detectable level indicates sensitization, meaning the immune system has produced antibodies to that substance. Sensitization does not always correspond to symptoms, so results are assessed in the context of exposure history and clinical presentation rather than in isolation.
