Allergen, Food, Oyster IgG
Also known as: OYSTER IGG
Use
The Allergen, Food, Oyster IgG test is used to measure the levels of allergen-specific IgG antibodies to oyster protein in the patient's serum. This test helps in assessing the patient's exposure to oyster allergens. High levels of allergen-specific IgG might indicate a high level of exposure to oysters. However, IgG-based tests are generally used for research purposes or allergy screening and are not definitive diagnostics for food allergies.
Special Instructions
Refer to 'Allergen Specimen Collection Instructions' at ARUP Laboratories' website for detailed specimen collection procedures. Ensure that serum is separated from cells as soon as possible, within two hours of collection, and transferred to ARUP's standard transport tube. The minimum required volume of serum is 0.25 mL.
Limitations
This test does not confirm or rule out the presence of an allergic reaction or allergy to oysters. A positive IgG response indicates immunological exposure and does not necessarily correlate with clinical symptoms. This test has not been cleared or approved by the FDA and should be used in conjunction with other diagnostic methods and clinical evaluations. Results may be affected by the hemolysis, icteric, or lipemic conditions of the serum specimen.
