This test will yield only one result - it will not differentiate between precipitins. If specific result is needed, please order individual precipitin. This panel includes Aspergillus niger, Aspergillus flavus and Aspergillus fumigatus.
Note: 0.25 mL serum is required for one precipitin. Add 0.1 mL for each additional precipitin ordered.

Immunodiffusion (Precipitin Aspergillus Polyvalent Mix IgG)
Allergic Bronchopulmonary Aspergillosis: Immunoglobulin E level (IGE), Aspergillus fumagatus #1 (ASPF1), Aspergillus niger (ASPNG), Aspergillus flavus (ASPFL), Aspergilllus fumagatus #6 (ASPF6), Aspergillus fumagatus specific IgE (RM3), Aspergillus fumagatus specific IgG (TGMIS) Hypersensitivity Screening Antigens: Thermoactinomyces vulgaris (TH3), Micropolyspora faeni (T1), Candida (CAND), Pigeon serum (EB1), Aureobasidium pullulans (TH5)
Precipitating IgG antibodies are often present in serum of patients with hypersensitivity pneumonitis (HP) due to exposure to enviromental antigens. The serum precipitin test assists in the diagnosis of HP.
