Allergen, Food, Tuna IgG
Also known as: TUNA IGG
Use
This test is used to measure the levels of IgG antibodies specific to the tuna allergen in the serum. Such testing is part of assessing a patient's immunological response to tuna, which may be associated with delayed-type food allergies, although the clinical relevance of IgG in food allergy is not as well established as IgE testing.
Special Instructions
Not provided.
Limitations
The test detects IgG antibodies specific to tuna allergen but its clinical significance in food allergy assessment is not as established as IgE-based tests. Results less than 2.00 mcg/mL may indicate absent or undetectable levels. Hemolyzed, icteric, or lipemic specimens are unsuitable for analysis.
