Background
Erythrocyte sedimentation rate is an index of erythrocyte sedimentation rate under certain conditions, and is called erythrocyte sedimentation for short. The erythrocyte sedimentation rate of a healthy person usually fluctuates up and down within a narrow range, and does not have large ascending and descending changes, and under the interference of many cases, the erythrocyte sedimentation rate shows obvious increase. The erythrocyte sedimentation rate measurement is widely applied clinically, the result of erythrocyte sedimentation and clinical data are mutually contrasted to show that the erythrocyte sedimentation rate measurement has a plurality of applications in clinic, can assist in judging whether a patient organism has inflammation or not, whether a patient lesion has activity or not and the like, can provide parameters for clinical examination with important reference value, and a method of erythrocyte sedimentation rate detection is also commonly adopted as a test diagnosis mode clinically.
The Wei's method is the most classical and most traditional and most conventional and reliable method for detecting the blood sedimentation, and the Wei's method is also a conventional method recommended by the International Committee for standardization of hematology, but in practical application, the Wei's method is complex in process, needs manual operation, can only measure the final result of the blood sedimentation at a certain moment, is poor in specificity, has great limitation in application, and has strict requirements on the time for observing and recording. People have been seeking a simpler and more trouble-saving method for measuring the blood sedimentation in recent years, and the method is more familiar in that a blood sedimentation instrument is adopted, the blood sedimentation instrument can dynamically record the change of the whole blood sedimentation process, draw a curve of the erythrocyte sedimentation and reflect different diseases or different orders of the diseases, the method is more convenient and the detection time is not long, but the obtained detection result is influenced by a plurality of external factors, the cost of the instrument is higher, the instrument can not be popularized in all hospitals, and the instrument is large in size and cannot be carried. The inclined tube method can accelerate the blood sedimentation and shorten the inspection time, the result can be obtained only in 15 minutes, compared with the Weishi method, the waiting time of a patient can be greatly reduced, the blood taking amount can be reduced by 1/3 compared with the Weishi blood sedimentation method, the defects still exist, the complete contrast can not be realized with the Weishi method, the inclined tube method is only suitable for patients with high blood sedimentation under specific conditions, and has great limitation, and meanwhile, the change of the blood sedimentation process has important value for judging diseases, and the inclined tube method can not monitor the change of the blood sedimentation process.
