BackgroundAt present, fecal elastase-1 ELISA determination is the most sensitive and specific tubeless pancreatic function test available. However, the results are not available the same day in routine clinical practice. This prospective study aims at evaluating the sensitivity and specificity of the Elastase-1 Quick⢠Test by comparing the results with the ELISA test.MethodsThe study was composed of three groups: the screening-diagnosed cystic fibrosis (CF) patients (n = 28), the screened, but non-CF subjects (n = 36) and non-screened CF patients (n = 62). Pancreatic status (normal vs abnormal) was evaluated using the Pancreas Elastase-1 Quick⢠Test. Fecal elastase-1 concentration was determined with a commercially available ELISA kit, used as reference. The cut-off for abnormal results was set at < 200 μg/g of stool.ResultsThe Pancreatic Elastase-1 Quick Test⢠showed the following sensitivities and specificities in the studied groups: 92.8% and 96.6% in all subjects, 90.5% and 100% in screening samples, and 92.8 and 90.5% in CF patients.ConclusionPancreatic Elastase-1 Quick Test⢠proves to be a rapid and reliable option to qualitatively evaluate pancreatic function for diagnostic purposes in a clinical setting of CF care.
