Background

The four blood coagulation items belong to one of clinical laboratory examination items and belong to thrombotic disease examination. Is a necessary examination item before operation, a pre-thrombus examination item and a clinical oral anticoagulant drug patient monitoring. Before a patient is hospitalized and operated, a doctor always requires the patient to take blood to carry out 4 tests of blood coagulation, the four items of blood coagulation comprise prothrombin time, activated partial thromboplastin time, thrombin time and fibrinogen, and the aim is to know whether the hemostasis function of the patient is defect-free before the operation so as to prepare in advance and prevent the large bleeding in the operation from taking measures. The hemostatic function of the human body is very important. When people accidentally injure and bleed, the hemostatic function quickly plays a role, so that blood is coagulated to plug wounds to stop bleeding, and the blood is prevented from being lost in large quantity. When a patient needs an operation, a doctor must know the hemostasis function of the patient in advance, such as poor hemostasis function, and the patient may bleed so much during the operation that an operation accident occurs and even die.

However, although it is common knowledge that conventional coagulation tests generally require a large-scale facility to perform the test, and the coagulation time is measured by microwaves, and the protein fibers in blood coagulate in the blood coagulation process, and thus the blood has a certain viscosity after a certain period of time, it is difficult to purchase a coagulation facility at a sufficient cost for hospitals that do not have good conditions because the purchase cost of the coagulation facility is high and the coagulation test time is long in less developed areas, and it is difficult to efficiently develop the coagulation test in less developed areas because the cost of the coagulation test is high for patients.
