Red blood cell nine-point diagram analysis

The red blood cell quantogram analysis is based on the hemoglobin concentration in each red blood cell after the instrument examination and analysis, and the hemoglobin distribution width (HDW) value in the red blood cells is calculated. According to the analysis of the red blood cell size and the hemoglobin content in a single red blood cell, the red blood cells are divided into 9 regions, and a nine-point map of red blood cell volume and pigment content distribution is obtained. The erythrocyte nine-point map allows morphological analysis of red blood cells to leap to a new level and can be used to identify different disease states, including red blood cell morphological changes associated with anemia - its performance is unquestionable, more reliable, and more efficient. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: You should fast after 8 pm on the day before the medical examination. Normal value According to the actual situation of the patient, the combined image analysis is analyzed. Clinical significance Abnormal results: Scanning each red cell through Flowcell by laser irradiation, low-angle scattered light (2°~3°) is used to measure cell volume; high angle (5°~15°) scattered light measures hemoglobin concentration in each red blood cell (CH) And hemoglobin content average CHCM. These two values ​​are not affected by the number of red blood cells and hemoglobin determination. The hemoglobin distribution width (HDW) value in the red blood cells can also be calculated based on the hemoglobin concentration in each red blood cell. According to the actual situation of the patient. People who need to be examined are suspected of having a blood disease. Precautions Inappropriate crowd: None. Taboo before the test: Do not eat too greasy, high-protein foods the day before the test, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. After 8 pm on the day before the medical examination, you should fast. Requirements for examination: When taking blood, you should relax your mind to avoid the contraction of blood vessels caused by fear and increase the difficulty of blood collection. Inspection process Vascular blood collection was used for testing. Before venous blood collection, carefully check that the needle is securely installed and that there is air and moisture in the syringe. The needle used should be sharp, smooth, ventilated, and the syringe should not leak. Firstly, the skin was disinfected from the inside to the outside and clockwise from the selected venipuncture with a 30g/L iodine swab. After the iodine was volatilized, the iodized trace was wiped out in the same way with a 75% ethanol swab. Fix the lower end of the venipuncture site with the thumb of the left hand, hold the syringe syringe with the thumb and middle finger of the right hand, and fix the needle lower seat with the index finger, so that the bevel of the needle and the scale of the syringe are upward, and the needle is inclined along the vein to make the needle and the skin obliquely penetrate the skin at an angle of 30°. Then, through the vein wall, enter the venous cavity forward at an angle of 5°. After seeing the blood return, the needle will be probed into the spot to avoid the needle slipping out when the blood is collected; but it is not possible to use a deep puncture to avoid hematoma, and immediately remove the cuff. Needle plug can only be pumped out, can not be pushed in, so as to avoid injecting air into the vein to form a gas plug, causing serious consequences. Remove the syringe needle and slowly inject the blood into the anticoagulation tube along the tube wall to prevent hemolysis and foam. A blood sample was taken and analyzed by an analytical instrument to obtain a nine-point chart. Not suitable for the crowd Hemophilia and diffuse intravascular coagulation. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
