Prothrombin time tester

The prothrombin time detector is an instrument used in clinical laboratories. It is mainly used to detect the prothrombin time of the human body, which is an important indicator for measuring blood coagulation. The instrument adopts the coagulation method prothrombin time determination system, which consists of a computer system, a reaction cup, a microplate, a detection plate, a sampler, an incubation module, a constant temperature incubation module, a plate washing module, a timer, etc.

The working principle of the instrument is to use the coagulation method prothrombin time determination system to add the sample to be tested and the control solution to the corresponding positions on the microplate. After adding the prothrombin reagent, incubate under the set reaction conditions, and then add the coagulant. The prothrombin in the sample and the control solution is coagulated by the coagulant, and the bleeding clotting time is calculated based on the color change or electrochemical change on the microplate.

This instrument is mainly used to detect human prothrombin time. The normal reference range of prothrombin time is 11-18 seconds. Prothrombin time reflects the functional status of the exogenous coagulation system, and its significant prolongation or shortening indicates corresponding abnormalities. Significant prolongation may be seen due to reduced plasma prothrombin activity (such as hypocoagulable state, liver disease, disseminated intravascular coagulation, systemic lupus erythematosus), errors in plasma prothrombin monitoring methods (such as large differences in multiple measurement results), coagulation factors Deficiency, hereditary or acquired fibrinogen reduction or abnormality, etc.; significantly shortened prothrombin time may be seen in increased plasma prothrombin activity (such as vitamin K deficiency, DIC), etc.

In short, the prothrombin time detector is an instrument used in clinical laboratories. It is mainly used to detect the prothrombin time of the human body and has important clinical application value.
