ASPERGILLUS ANTIBODY IgG, SERUM

THIS TEST MEASURES THE LEVEL OF IMMUNOGLOBULIN G (IGG) ANTIBODIES AGAINST ASPERGILLUS FUNGI IN THE BLOOD. ASPERGILLUS IS A COMMON TYPE OF MOLD THAT CAN CAUSE INFECTIONS, ESPECIALLY IN PEOPLE WITH WEAKENED IMMUNE SYSTEMS. ELEVATED LEVELS OF ASPERGILLUS IGG ANTIBODIES MAY INDICATE PAST OR CURRENT EXPOSURE TO ASPERGILLUS AND SUGGEST A POSSIBLE FUNGAL INFECTION OR COLONIZATION. THIS TEST IS OFTEN USED IN CONJUNCTION WITH OTHER DIAGNOSTIC TESTS TO HELP DIAGNOSE ASPERGILLOSIS, PARTICULARLY IN PATIENTS WITH UNDERLYING CONDITIONS THAT WEAKEN THE IMMUNE SYSTEM.
