Mean corpuscular hemoglobin concentration (MCHC)

The mean erythrocyte hemoglobin concentration (MCHC), which is the average number of grams of hemoglobin per liter of blood cells, expressed in g/L. The formula is as follows: MCHC = grams of hemoglobin per liter of blood (g/L) / ratio of red blood cells per liter of blood (L/L). Reduce small cell hypochromic anemia. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Tips: When you take blood, you should relax your mind, avoid the contraction of blood vessels caused by fear, and increase the difficulty of blood collection. Normal value The mean red blood cell hemoglobin concentration (MCHC) reference value is 300-360*g/L for males, 300-360*g/L for females, and 300-360*g/L for newborns. Clinical significance Abnormal results: 1. Increase hyperchromic anemia, severe vomiting, frequent diarrhea, polycythemia vera, chronic carbon monoxide poisoning, heart failure and so on. 2. Reduce small cell hypochromic anemia. The people who need to be examined have people with symptoms such as palpitations, shortness of breath, fever, vomiting, and diarrhea. 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, 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 Inspection method: draw blood. Not suitable for the crowd Have a coagulopathy such as hemophilia. Adverse reactions and risks Subcutaneous hemorrhage: subcutaneous hemorrhage due to less than 5 minutes of compression time or blood draw technique.
