Double disks synergy test (DDST) and combined disks test (CD) were evaluated to predict the presence of metallo--lactamase in 70 Pseudomonas aeruginosa isolates recovered from cystic fibrosis and non-cystic fibrosis patients. DDST CAZ-EDTA 1 cm and CD IMP-EDTA tests showed the best accuracy (94.3%). Furthermore, for other combinations, accuracy unsatisfactory was obtained.
