Immunoreactive trypsinogen (IRT) is used as part of some newborn screening programs to screen for cystic fibrosis (CF). It may be used in conjunction with a sweat chloride test and/or a cystic fibrosis gene mutation panel to help identify CF. IRT may also sometimes be used to help detect acute pancreatitis.

Application of DNA analysis in a population-screening program for neonatal diagnosis of cystic fibrosis (CF): comparison of screening protocols. OBJECTIVE: To examine immunoreactive trypsinogen (IRT)-based screening for cystic fibrosis (CF) for recall rate, genotype distribution, and "borderline" sweat test results.

Blood immunoreactive trypsinogen (IRT) is elevated in newborns with cystic fibrosis (CF) and has been used as a neonatal screening test. However, not only is the benefit of early diagnosis unknown, but also the sensitivity, specificity, and time related decline of IRT values have yet to be comprehensively evaluated.

This is a protein produced by the pancreas that is linked to CF. programme for immunoreactive trypsinogen (IRT), the biomarker for CF. Dried blood spot specimens (DBS) were used to evaluate the performance of laboratories that screen babies for CF. Methods DBS were prepared from human whole blood enriched with physiologically relevant levels of IRT. In this study, we hypothesised that immunoreactive trypsinogen (IRT) levels, used in NBS as a marker of pancreatic disease and function, may reflect the degree of CFTR dysfunction in each individual and therefore would help to identify those with CRMS/CSPID who are later at risk for meeting the criteria of CF.

In cystic fibrosis newborn screening (CFNBS), immunoreactive trypsinogen (IRT) and pancreatitis-associated protein (PAP) can be used as screening parameters. We evaluated the IRT × PAP product as second-tier parameter in CFNBS in newborns with elevated IRT.

Proceedings of the 2010 Newborn Screening and Genetic testing On May 23-24, 2011, a workshop entitled "Immunoreactive Trypsinogen (IRT) as a Biomarker for Cystic Fibrosis: Technical Issues and Challenges" was held in Annapolis, Maryland. The two-day workshop was co-hosted by the National Newborn Screening and Genetics Resource Center, Austin, Texas, and the Association of Public Health Laboratories, Silver Of 1004 (1.13%) neonates with immunoreactive trypsinogen > or = 99th centile, 912 (90.8%) had no identifiable mutation.
