Allergen Specific IgG Western Ragweed
Use
This test measures the level of allergen‑specific Immunoglobulin G (IgG) antibodies in serum directed against Western Ragweed. The presence of IgG antibodies may reflect exposure or sensitization to the allergen, but should be interpreted within the broader clinical context. A positive result alone does not confirm allergy or clinical reactivity without correlation with patient history and symptoms.
Special Instructions
Not provided.
Limitations
IgG antibody testing for allergens does not differentiate between sensitization and true clinical allergy. Results should be considered in conjunction with clinical findings; false positives may occur due to cross‑reactivity or non‑specific exposure. This test is not intended for standalone diagnostic use.
