Cystic fibrosis (CF) screening by means of immunoreactive trypsin (IRT) lacks specificity: only 1 out of 12 hypertrypsinemic neonates has cystic fibrosis. We propose here to analyse the KM.19 polymorphic site in the dried blood spots as an additional test in hypertrypsinemic neonates. A blind retrospective study of 114 hypertrypsinemic samples has been performed after polymerase chain reaction. Twenty-seven of 37 CF (74%) were homozygous for allele 2 (2-2) and could have been diagnosed on the 15th day of life. Fifty-five percent of the infants tested were homozygous for allele 1 (1-1), a very rare feature in CF, conferring them a probability of being normal of 99.8%. At the moment, this test could be of great help in the CF screening, even better than the search for the delta F508 mutation for which 45.9% of CF patients are homozygous.
