Title:
AUTOMATIC ANALYSIS DEVICE AND AUTOMATIC ANALYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2011/132525
Kind Code:
A1
Abstract:
Disclosed is a technique that, in an automatic analysis device that mixes a sample and a reagent and measures chronological changes in the liquid mixture, automatically determines or predicts a linear range that is characteristic to the sample and that arises in the reaction process. In the present disclosures, reaction process data are approximated by a function, and the curved portion of the initial period or the latter period of the reaction is automatically determined on the basis of said function. The linear range that excludes the curved portion is determined for each sample, and a test value is calculated using light absorption data of the determined linear range. Also, the linear start time-point of the initial period of the reaction is automatically determined on the basis of light absorption data obtained until partway through the reaction process, the linear range is predicted on the basis of said linear start time-point and a linear end time-point expected ahead of time, and a predicted value is calculated on the basis of the results thereof.
