Description

technical field [0001] The invention relates to the technical field of blood cell analysis, in particular to a double-cell measurement method and device for specific reaction protein CRP. Background technique [0002] There are two main methods for the detection of specific reaction protein CRP: one is to detect CRP in a biochemical analyzer, centrifuge the blood sample first, take out the serum, add the serum and reaction reagents to the reaction pool, measure the CRP content by the turbidimetric method, and test The time is about 90 seconds, and this method is suitable for hospitals with large sample volumes; the other is to use a specific protein analyzer to detect CRP alone, manually use quantitative instruments to add blood samples and reaction reagents to the reaction pool, and measure the CRP content by scattering turbidimetry. The fastest test time is 90 seconds. This method is cumbersome to operate and is suitable for outpatient and emergency departments. [0003] ...
