Allergen, Food, Baker's Yeast IgG
Also known as: YEAST IGG
Use
The Allergen, Food, Baker's Yeast IgG test measures the levels of IgG antibodies specific to baker's yeast. This test is used to assess an individual's immune response to baker's yeast, which can help in understanding dietary intolerance or hypersensitivity. Elevated IgG levels may indicate a heightened immune response, potentially resulting in dietary-related symptoms. However, this test is not used for diagnosing allergies as defined by the presence of IgE antibodies.
Special Instructions
Patients should ensure adequate serum volume for testing. Follow the specimen collection and handling instructions closely to avoid rejection due to hemolysis, icterus, or lipemia.
Limitations
This test is not intended for diagnosing allergies, as it measures IgG rather than IgE antibodies. Results should not be used as the sole basis for dietary restrictions or diagnoses without considering clinical evaluation and other diagnostic factors. Interpretation should be done cautiously in the context of clinical evaluation due to the nature of IgG responses in chronic exposure without causing symptoms.
