Objectives: The objective of this study was to assess the dye 2',7'-dichlorofluorescein (DCF assay in screening for alterations in polymorphonuclear cell (PMN) and monocyte (MC) oxidative burst of cystic fibrosis (CF) patients. Study design: 56 CF patients aged between 2 and 20 years were investigated. Purified cells were stimulated with phorbolmyristate acetate: (PMA) and zymosan (ZX). A range for DCF fluorescence for PMA- and ZX-stimulated and non-stimulated cells was established based on data from 60 healthy controls. Results: PMNs showed both enhancement and impairment. A deficient oxidative burst was detected in a total of 14 CF patients caused by abnormally high mean fluorescence intensity (MFl) of resting cells. Enhanced oxidative burst was seen in 6 CF patients. CF patients responded differently to PMA or ZX stimulation. Pseudomonas aeruginosa colonization significantly enhanced (p
