erythrocyte sedimentation rate

Erythrocyte sedimentation rate (ESR) refers to the rate at which red blood cells settle under certain conditions, referred to as erythrocyte sedimentation rate. In healthy people, the blood sedimentation value fluctuates within a narrower range. ESR is significantly increased in many pathological conditions. Erythrocyte sedimentation is the result of multiple factors interacting. Slowing down, due to the significant increase in the number of red blood cells and the severe decrease in fibrinogen content, the dehydration blood concentration, polycythemia vera and diffuse intravascular coagulation caused by various reasons can be seen in the increase of red blood cells and fibrinogen. Severely reduced. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Below normal, there are various causes of dehydration, polycythemia, and disseminated intravascular coagulation. 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 of adult cattle?-12mm/h Above normal: Above normal, it is seen in active tuberculosis, rheumatic fever, severe tissue destruction, and anemia. negative: Positive: Tips: You should fast after 8 pm on the day before the medical examination. Normal value Westergren method: Adult male 0-15mm / h. Adult women 0-20mm / h. Pan's method: Adult male 0-10mm / h. Adult female 0-12mm / h. Clinical significance Abnormal results: Men are greater than 15mm/h and women are 20mm/h, which is faster. May be physiological women during menstruation, 3 months of pregnancy to 1 month after delivery. Pathologically, it is acute inflammation, connective tissue disease, active tuberculosis, rheumatic fever, severe tissue destruction, anemia, malignant tumor, hyperglobulinemia, and heavy metal poisoning. Slowing down, due to the significant increase in the number of red blood cells and the severe decrease in fibrinogen content, the dehydration blood concentration, polycythemia vera and diffuse intravascular coagulation caused by various reasons can be seen in the increase of red blood cells and fibrinogen. Severely reduced. People who need to be examined have people with symptoms such as inflammation, anemia, and tuberculosis. High results may be diseases: short bone backbone tuberculosis, idiopathic hypereosinophilic syndrome, bronchial central granulomatosis considerations 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 Hemophilia and diffuse intravascular coagulation. Adverse reactions and risks Subcutaneous hemorrhage: subcutaneous hemorrhage due to less than 5 minutes of compression time or blood draw technique.
