Method Comparison of Two Test Kits for the Determination of Elastase/α1-Proteinase-Inhibitor Complex
A method comparsion of the 5h-elastase/α1-proteinase-inhibitor test kit with a newly developed 2 h-version was performed. The within-run and between-days coefficients of variation as well as the recovery of the assigned values were satisfactory for both test kits. Good agreement was found between the 2 h- and 4 h-test kits using specimens from 1600 patients. In conclusion, the 2 h-test kis can be used as an alternative for the determination of elastase/α1-proteinase-inhibitor complex.
