Erythrocyte sedimentation rate (ESR)

After the blood is added with anticoagulant, it is placed in a special glass tube to measure the distance that the red blood cells fall within a certain period of time, which is called the erythrocyte sedimentation rate, referred to as erythrocyte sedimentation rate. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Reduce erythrocytosis caused by various causes, such as dehydration, polycythemia, hereditary spherocytosis, fibrin reduction, etc. Normal value: Wei's adult male: 0-15mm/h Wei's adult woman: 0-20mm/h Pan's adult male: 0-10mm/h Pan's method adult model?-12mm/h Above normal: More than normal values ​​are more common in multiple myeloma, macroglobulinemia (acute infective endocarditis, kala-azar, etc.). negative: Positive: Tips: You should fast after 8 pm on the day before the medical examination. Normal value Wei's method: Adult male 0 ~ 15mm / h. Adult women 0 ~ 20mm / h. Pan's method: Adult male 0 ~ 10mm / h. Adult women 0 ~ 12mm / h. Clinical significance Abnormal results: 1. Increase: (1) Physiologically increasing women's menstrual period, pregnancy, children under 12 years old, and the elderly. (2) Significantly increased pathological increase in multiple myeloma, macroglobulinemia (acute infective endocarditis, kala-azar, systemic lupus erythematosus, cirrhosis, etc.), malignant lymphoma, leukemia, severe Anemia, sarcoma, severe acute bacterial infection, collagen disease, portal and biliary cirrhosis, ulcerative colitis, severe kidney disease, early viral pneumonia, etc. Moderate increase in acute or chronic infection, rheumatic fever, rheumatoid arthritis, myocardial infarction, pulmonary infarction, malignant tumor with necrosis, hypercholesterolemia, hyperthyroidism or hypothyroidism, lead poisoning, zinc poisoning, Tuberculosis, kidney disease, acute viral hepatitis, allergic purpura, etc. 2. Slow down: Less meaningful. It is common for erythrocytosis caused by various causes, such as dehydration, polycythemia, hereditary spherocytosis, and fibrin reduction. People who need to be examined have people with fever, fatigue, loss of appetite, bleeding or anemia. Low results may be diseases: high gout results may be diseases: macroglobulinemia, sciatica, pericardial incision syndrome, pediatric allergic purpura matters needing attention First, the precautions before blood draw: 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. 2. After 8 pm on the day before the medical examination, you should fast. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. Second, after blood draw should pay attention to: 1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma. 2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended. 3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved. 4. If there is localized congestion, use a warm towel after 24 hours to promote absorption. Inspection process The examination process: blood is drawn, blood is taken for examination, and venous blood is generally taken, and blood is drawn by a doctor or a nurse. The amount of blood drawn is determined according to the difference of the test content and the number of items. The blood volume is usually 2-20 ml, and the maximum is not more than 50 ml. Then, after the anticoagulant is added to the blood, it is placed in a special glass. In the tube, the distance at which the red blood cells fall within a certain period of time is measured. Not suitable for the crowd Have a coagulopathy such as hemophilia. Adverse reactions and risks Discomfort: There may be pain, swelling, tenderness, and visible subcutaneous ecchymosis at the puncture site.
