Allergen, Food, Strawberry IgG
Also known as: STRWBRYIGG
Use
The Allergen, Food, Strawberry IgG test is used to measure the levels of specific IgG antibodies to strawberry allergens in the blood. IgG antibodies are produced as part of the immune response to allergens, and measuring these levels can help in assessing exposure to strawberry allergens and understanding allergic responses. This test can be relevant for individuals with suspected food allergies or those undergoing allergy assessments. IgG testing can aid healthcare providers in evaluating dietary sensitivities and in personalized allergy management.
Special Instructions
Patients should ensure that serum is separated from cells as soon as possible or within two hours of collection to maintain sample integrity. The serum must then be transferred to an ARUP standard transport tube. It is important to refer to allergen specimen collection instructions for proper handling and preparation of the specimen. Additionally, do not submit samples to ARUP for this test if in New York state, as it is not permitted there and no laboratories are New York approved.
Limitations
The test is limited as a diagnostic tool for determining dietary allergies because IgG antibodies do not confirm an allergic reaction. The presence of IgG antibodies indicates exposure to the allergen but does not necessarily correlate with clinical symptoms of an allergy. False positives or negatives can occur based on cross-reactivity with other allergens or varying immune responses in individuals. The test does not replace clinical evaluations and should be interpreted in conjunction with a comprehensive allergy assessment by a healthcare provider.
