Although the mention of POCT only began to appear in the 1990s, in fact, in the 1970s, with the development of intensive care medicine, the need for POCT appeared. In the hemostatic test, clinicians have an urgent requirement for rapid reporting and reliable results. In the case of emergency or perioperative bleeding, the average turnaround time (TAT) of the laboratory is about 45-90 minutes. Generally, the time of the standardized laboratory is about more than that of POCT. 1.5h long. There are significant differences in specimen handling and preparation for POCT and laboratory testing of coagulation. The simplicity of POCT and the rapid detection of results have therefore opened the door to the application of POCT in hemostatic testing. POCT measurement does not require blood samples to be sent for examination, and there is no need to wait for a report, and the patient's dosage can be adjusted quickly. The laboratory only reports the emergency and critical values by telephone, and most of them are uploaded to the hospital information system for the doctors to check by themselves. The time saved by POCT can have some intangible value, especially in the intensive care unit and the operating room. The length of the operation time, the amount of treatment, and the time often means saving the cost of medical treatment, and it can also reduce unnecessary blood transfusion in hemostatic thrombus testing. , the advantage is obvious.
In terms of the value of information, although most of the test results are quantitative indicators, for clinical diagnosis, it often comes down to the nature of "yes" and "no", that is, what to do next, that is, clinical decision-making. Difficulty in decision-making is not only the greatest harm to patients, but also makes doctors very helpless in the face of patients in pain. If there is no need to send specimens for testing, testing can be carried out when preliminary clinical judgment is available, which will help clinicians to the greatest extent, and also reflects the important value of testing in reducing the uncertainty of clinical decision-making.
