Abstract

DiaPack3000, developed as the next model following DiaPack2000, is a specific IgE antibody analyzer. Its measurement time is 12 min/test, and it can perform 90 tests in 39 min. This analyzer enabled the shortening of measurement time, improvement of processing capacity compared with previous analyzers, insertion of samples at any time, and enhanced operability. We evaluated the basic performance of DiaPack3000, and compared it with those of DiaPack2000 and Phadia5000. DiaPack3000 was found to be superior to DiaPack2000 in terms of reproducibility and sensitivity. Dilution linearity was obtained throughout the measurement range. In addition, no carryover was observed. The coefficients of correlation between DiaPack3000 and DiaPack2000 were 0.882–0.999 in six items. In addition, the rates of agreement of the class with Phadia5000 were 80.7–91.9% in six items. The performance of DiaPack3000 was adequate; therefore, DiaPack3000 could be more efficient for allergy testing in routine clinical practice than previous models.
