Blood sample type identification and detection system

Abstract

The invention discloses a blood sample type identification and detection system. A sample channel is formed on a sample carrier, the sample channel is connected with a plasma identification unit at the tail end of a whole blood identification unit, and the sample channel is connected with a serum identification unit at the tail end of the plasma identification unit; the whole blood identificationunit comprises a whole blood identification sensor and a whole blood signal acquisition circuit, the whole blood identification sensor is arranged in the sample channel, and the whole blood signal acquisition circuit is connected with the whole blood identification sensor; the plasma identification unit comprises a plasma identification sensor and a plasma signal acquisition circuit, the plasma identification sensor is arranged in the sample channel, and the plasma signal acquisition circuit is connected with the plasma identification sensor; the serum identification unit comprises a serum identification sensor and a serum signal acquisition circuit, the serum identification sensor is arranged in the sample channel, and the serum signal acquisition circuit is connected with the serum identification sensor. The blood sample type identification and detection system can be used for judging the type of a blood sample before the immune detection system works so as to meet the judgment requirements of different item detection.

Description

technical field [0001] The invention relates to a blood sample type identification and detection system, which belongs to the technical field of medical in vitro diagnosis. Background technique [0002] Clinically, anticoagulation, coagulation promotion and other sample preservation methods are widely used. Different sample processing methods have varying degrees of impact on clinical test results, which are reflected in the impact on sample matrix effects and instrument signal acquisition. In the immunoassay system, the antigen-antibody immune response is easily affected by conditions such as ion concentration, pH, and hematocrit, so the response of the immune response to the sample type is particularly obvious. [0003] The collection and separation of blood samples is crucial in clinical testing and is one of the key links in quality control before diagnostic analysis. Traditional immunodiagnosis requires specifying the sample type, which not only invisibly increases th...
