The function and principle of dynamic erythrocyte sedimentation rate tester

The main purpose of the dynamic erythrocyte sedimentation rate tester is to detect the sedimentation distance of red blood cells in peripheral blood per unit time, that is, the erythrocyte sedimentation rate. It is routinely used to observe various pathological factors, such as inflammation, tissue damage, and vascular disease, leading to abnormal red blood cell function and increased or decreased red blood cells.
Erythrocyte sedimentation rate, also known as erythrocyte sedimentation rate, is one of the experimental methods for detecting disease activity indicators. Increased results are common in various inflammations, active stages of tuberculosis, rheumatism, malignant tumors, etc., but may also increase in late pregnancy and after surgery. . Slowed results may be seen in cachexia, malnutrition, liver and kidney disease, etc. However, this test result is generally only used as a reference and needs to be comprehensively analyzed in conjunction with clinical conditions when necessary.
Please note that the above information is for reference only. If you have specific questions, please consult professionals.
The principle of the dynamic erythrocyte sedimentation pressure tester is to use flow cytometry to detect the erythrocyte sedimentation rate, and use the erythrocyte sedimentation rate as an indicator to diagnose and differentially diagnose diseases. The erythrocyte sedimentation rate value will undergo physiological changes due to age, gender, physiological factors, pathological factors, etc., so the measurement results need to be compared with your own situation and the normal value range.
Erythrocyte sedimentation rate, or erythrocyte sedimentation rate, refers to the speed at which red blood cells settle under certain conditions. The sedimentation test is based on the principle of dynamics. Anticoagulated whole blood is injected into the power cup. The red blood cells are under the liquid surface of the capillary wall between the blood components and the glass tube. They naturally sink per unit time by gravity. The speed of red blood cell sinking is called Weizmann's formula of erythrocyte sedimentation rate: ESR=1.11×(Rg/H)t, where ESR is the erythrocyte sedimentation rate, Rg is the acceleration of gravity, and t is time. The accuracy of the erythrocyte sedimentation rate value depends on the volume ratio of anticoagulant to blood. Blood samples should be fresh and sent for testing immediately after collection.
