The full name of ESR is erythrocyte sedimentation rate, and the English abbreviation is ESR. It is a non-specific test item. Unit: MM/H (mm/h) 23mm/h does not support erythrocyte sedimentation rate (ESR) in rheumatic diseases, which means ESR is a non-specific test item. In other words, an accelerated ESR does not determine what disease you have, and a normal ESR does not mean that you are not sick. The determination of erythrocyte sedimentation rate can help us understand the disease, observe its development and change, and also need to combine other laboratory results and clinical data to help us diagnose the disease. To judge whether the ESR result is normal or not, it is necessary to distinguish between sexes. The reference range (Webster's method) is 0~ 15mm/ 1 hour for men and 0~20mm/ 1 hour for women. The erythrocyte sedimentation rate can be accelerated due to physiological factors, such as women's menstrual period and pregnancy can reach about 40 mm, and children and elderly people over 50 can be slightly faster than the reference range, which may have nothing to do with the disease at this time. Accelerated ESR is often related to the following diseases: △ inflammatory diseases, such as acute bacterial inflammation, will accelerate ESR within 2~3 hours; △ Various acute systemic or local infections, such as active tuberculosis, nephritis, myocarditis, pneumonia, purulent encephalitis, pelvic inflammatory disease, etc. △ Various collagen diseases, such as rheumatoid arthritis, systemic lupus erythematosus, scleroderma, arteritis, etc. △ Tissue injury and necrosis, such as large-scale tissue necrosis or injury, major surgical injury, myocardial infarction, lung infarction, fracture, severe trauma, burns and other diseases can also accelerate the erythrocyte sedimentation rate; △ When suffering from severe anemia, hematological diseases, chronic hepatitis, liver cirrhosis, multiple myeloma, hyperthyroidism, heavy metal poisoning, malignant lymphoma, macroglobulinemia, chronic nephritis and other diseases, the erythrocyte sedimentation rate can also show an obvious acceleration trend. Accelerated erythrocyte sedimentation rate is valuable for rapidly developing malignant tumors: when surgical resection of tumors or chemotherapy and radiotherapy are effective, erythrocyte sedimentation rate can be slowed down; When tumor recurs or metastasizes, the erythrocyte sedimentation rate can be further accelerated. Benign tumors generally do not accelerate or decelerate, so this project can help to preliminarily judge the nature of tumors. The speed of ESR is also helpful to observe the changes of the disease. For example, the degree of accelerated ESR of rheumatism and tuberculosis is often related to the severity of the disease. The erythrocyte sedimentation rate accelerated in active stage; The condition improved and the erythrocyte sedimentation rate slowed down; Inactive ESR can be restored to the reference range. Therefore, the determination of ESR can roughly infer the development of the disease and observe the therapeutic effect. For example, the erythrocyte sedimentation rate (ESR) of patients with lupus erythematosus has changed from stable to accelerated, indicating that the disease has entered an active period and has been stable in the reference range for a long time, indicating that the disease has been controlled.
