The chromogenic βLACTA™ test was evaluated to detect ceftazidime resistance in P. aeruginosa isolates from patients with cystic fibrosis. Best results were obtained after one hour of incubation with low sensitivity (64.1%), high specificity (98.3%), and negative and positive predictive values of 80.3% and 96.2%, respectively.
