P304 Oral glucose tolerance test in diagnosis of cystic fibrosis-related diabetes in the era of continuous glucose monitoring

Oral glucose tolerance testing (OGTT) is the recommended screening for cystic fibrosis-related diabetes (CFRD). Increasing evidence for benefit of early detection of CFRD has led to utilisation of continuous glucose monitoring (CGM). One-hour plasma glucose (1-h PG) during the oral glucose tolerance test (OGTT) is known to be an accurate predictor of type 2 diabetes.
