[Aspergillus serology, from yesterday to today for tomorrow]

Anti-Aspergillus antibody detection has been performed for over 50 years for the diagnosis of different chronic Aspergillus infections, starting with aspergilloma and later with chronic necrotizing pulmonary aspergillosis. It also enters into definition criteria for allergic broncho-pulmonary aspergillosis and contributes to the initial diagnosis of the aspergillosis, to the follow-up under treatment or to the detection of exacerbations. For the acute invasive aspergillosis, antibody detection has low interest compared to galactomannan antigen detection. Serology results have to be interpreted together with other clinical, radiological and biological, mycological criteria. This review describes the origins, the technical evolutions and the current place of Aspergillus serology in France. Finally, future improvements are discussed.
