Abstract

Authors´ conclusions: both strategies, inmunoreactive trypsinogen and pancreatitis-asociated protein or inmunoreactive trypsinogen and DNA mutation detection with sequencing if necessary, perform well as cystic fibrosis screening. The first one has more false positive results; the second needs DNA technology.The combination of both strategies could be the best option to reduce false positive results. Taking in account these aspects, local authorities must decide the best strategy.

Reviewers´ commentary: this study shows no extra benefits for inmunoreactive trypsinogen and pancreatitis-asociated protein, when compared to habitual screening strategies. Inmunoreactive trypsinogen and DNA mutation detection with sequencing if necessary, would allow to diminish the number of false positives but it would detect a greater number of carriers. The combination of both detects less number of carriers and equivocal diagnosis than the previous one. There is no data about economical cost. These two last tests would be two valid options to consider in screening programs of cystic fibrosis.
