Serum complement C9 content

C9 is one of the 11 complement components in the blood. Determination of C9 content contributes to the diagnosis and treatment of various autoimmune diseases. Reduced: seen in liver disease, kidney disease, etc. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Reduced: seen in liver disease, kidney disease, etc. Normal value: Normal value: 47-69 mg / liter Above normal: No relevant information. negative: Positive: Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. The alcohol content in the blood directly affects the test results. After 8 pm on the day before the medical examination, fasting should be done to avoid affecting the detection of indicators such as blood glucose in the second sky. Normal value 47 to 69 mg / liter. (Note the specific reference value depends on each laboratory.) Clinical significance Reduced in liver disease, kidney disease, etc. Low results may be diseases: liver hemangioma, kidney damage 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 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. If you have a history of fainting blood, please explain in advance and 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 dizziness, such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of sugar water, 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. Third, venous blood 2ml, no anticoagulation, separation of serum for determination. Inspection process The serum to be tested was diluted 1:20, and 0.2 ml of the serum to be tested was aspirated into a test tube, and 3.8 ml of barbital buffer was added and mixed. Two tubes close to the standard tube were selected and read at a wavelength of 542 nm using a spectrophotometer to find a tube that was closer to the standard optical density number. The total complement value was determined according to the standard based on the amount of diluted serum added to the tube. Not suitable for the crowd There are no special taboos. Adverse reactions and risks No related complications and hazards.
