Galactomannan detection in broncho-alveolar lavage fluid for invasive aspergillosis in immunocompromised patients

To assess the diagnostic accuracy of galactomannan detection in BAL for the diagnosis of invasive pulmonary aspergillosis in people who are immunocompromised, at different cut-off values for test positivity, in accordance with the Cochrane Diagnostic Test Accuracy Handbook.

Our secondary objective is to study several possible sources of heterogeneity, see 'Investigations of heterogeneity'.

This is a protocol.
