Sumario:Invasive fungal diseases represent an increasing problem in the hospital environments, predominantly in the last two decades. The invasive aspergillosis (IA), induced by Aspergillus species, has been the main cause of death in severely immunocompromised patients, with mortality varying from 70 to 90%. Difficulties are found for diagnosing the IA. In vitro culture of biological material shows low sensitivity (<50%), besides the positivity usually occurs at the advanced stages of the infection. The test for detecting galactomannan has been the object of the present study, seeing that it represents a promising diagnostic tool, as a fast and non-invasive serological procedure. The objective of the present review is to survey the studies which have been performed by using methods for detecting galactomannan in samples from patients with distinct clinical pictures. Patients presenting suspicion and/or confirmed IA were also included, as well as the up-to-date trends in knowledge, application and utility of the test.
