Red blood cell rosette test

There are membrane surface immunoglobulins, FC and complement receptors on the surface of B cells. People who need to be examined: people who have symptoms such as blushing, dizziness, palpitations, bleeding, and fever. Basic Information Specialist classification: growth and development check classification: immunological examination Applicable gender: whether men and women apply fasting: not fasting Tips: After 8 pm on the day before the medical examination, you should fast, so as not to affect the detection of indicators such as blood glucose in the second sky. Normal value EA-RFC, EAC-RFC is 8% to 12%; The M-RFC was 8.5 ± 2.8%. Clinical significance In immunodeficiency diseases (such as no agammaglobulinemia, combined immunodeficiency), M-RFC decreased significantly, while EA-RFC and EAC-RFC also decreased. In chronic lymphocytic leukemia and hairy cell leukemia, M-RFC, EA-RFC, and EAC-RFC were significantly elevated. 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. 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 the doctor performs protein color test. Not suitable for the crowd There are no taboos. Adverse reactions and risks There are no related complications and hazards.
