Abstract

The invention discloses an intelligent rate method detection data processing method applied to a biochemical analyzer. The method comprises the following steps that accumulative slope mean values from start of reacting to stop of reacting are calculated; whether the analyzer conducts calculation according to a selected detection window and reports a result or conducts diluting for reworking is determined according to the fact that whether the formula (please see the formula in the description) is tenable or not and whether an inflection point is generated or not, wherein the inflection point means that three continuous accumulative slopes and regression coefficients are all decreased, and the subsequent accumulative slopes and regression coefficients are not increased any more. According to the method, low-concentration samples, normal-concentration samples and high-concentration samples can be automatically identified, misjudgment of the analyzer on a detection result is avoided, and the accuracy of the detection result is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical inspection and detection, in particular to an intelligent processing method for speed method detection data applied to a biochemical analyzer. Background technique [0002] According to the structure of the reaction device, automatic biochemical analyzers are mainly divided into two categories: flow type and discrete type. The discrete type means that the chemical reactions after mixing the samples to be tested and the reagents are all completed in their respective reaction cups. The discrete type is further divided into a typical discrete type and a centrifugal discrete type, and the typical discrete type is more common. The basic structure of a typical discrete automatic biochemical analyzer includes a sample system, a reagent system, a barcode reading system, a reaction system, a cleaning system, a colorimetric system and a program control system. The rate method refers to the method of conti...
