Aspergillus-positive lower respiratory tract samples in patients with the acute respiratory distress syndrome: a 10-year retrospective study

Annals of Intensive Care

Table 3 Serum and bronchoalveolar lavage fluid galactomannan antigen according to the probability of invasive pulmonary aspergillosis (Blot et al. algorithm [16])

	All (n = 27)	Proven/putative aspergillosis (n = 15)	Aspergillus colonization (n = 12)	p value^a
Positive serum galactomannan	9 (33)	7 (47)	2 (17)	0.22
Positive BAL fluid galactomannan	8 (30)	8 (53)	0 (0)	0.003

BAL bronchoalveolar lavage
^a p value comes from the Fisher exact test; an optical density (OD) ratio of 0.5 or greater for galactomannan antigen in serum and 1.0 for BAL fluid was considered positive
