Reticulocyte count (RC)

Reticulocytes are red blood cells that are not fully mature. The ribonucleic acid remaining in the cells is specially stained to form a "mesh" structure. The number of reticulocytes increased, indicating that the bone marrow hematopoietic function is strong. Found in hemolytic anemia, hemorrhagic anemia, pernicious anemia, and iron deficiency anemia and megaloblastic anemia treatment. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Found in aplastic anemia. Normal value: Adult: 0.5-1.5% Newborn: 2.0-6.0% Above normal: Found in hemolytic anemia, hemorrhagic anemia and so on. negative: Positive: Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. Normal value Adults are 0.5% to 1.5%, with absolute values ​​(24 to 84) x 109/L. The newborn is 2.0% to 6.0%, and the absolute value is (144 to 336) × 109 / L. Clinical significance The number of reticulocytes increased, indicating that the bone marrow hematopoietic function is strong. Found in hemolytic anemia, hemorrhagic anemia, pernicious anemia, and iron deficiency anemia and megaloblastic anemia treatment. Reticulocyte counts are reduced and are seen in aplastic anemia. Low results may be diseases: pediatric hereditary elliptic polycythemia results may be high disease: congenital erythrocyte membrane disease, hemolytic anemia caused by copper poisoning, warm antibody type autoimmune hemolytic anemia precautions 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 physical examination, fasting should be done to avoid affecting the detection of indicators such as blood glucose in the second sky. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. Guests with a history of fainting should explain in advance and we will make special arrangements. Second, should pay attention after blood draw 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 Blood test. Not suitable for the crowd Have a coagulopathy such as hemophilia. Adverse reactions and risks Dizziness or fainting: When blood is drawn, due to emotional overstress, fear, reflex caused by vagus nerve excitability, blood pressure drop, etc., the blood supply to the brain is insufficient to cause fainting or dizziness.
