erythrocyte alkali granule aggregation test

The erythrocyte alkali granule agglutination test is one of the auxiliary diagnostic indicators for lead poisoning. After the red blood cells are ruptured by alkali treatment, the hemoglobin is overflowed into a shadow cell. If the red blood cells remain, the RNA is granulated and deposited in the shadow cells, and then the blue particles are clearly seen after staining with the methylene blue. The counting method is similar to that of spotting red blood cells. Its meaning is the same as that of spotted red blood cells. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Tips: After the blood draw, symptoms such as dizziness, vertigo, fatigue, etc. should be immediately lying down, drink a small amount of sugar water, and then undergo a physical examination after the symptoms are relieved. Normal value The percentage of alkaline colored red blood cells is 0.004-0.008. Clinical significance Abnormal results: Increased poisoning of heavy metals (lead, mercury, silver, strontium), increased toxicity of organic compounds (nitrobenzene, aniline), hemolytic anemia, pernicious anemia, leukemia, malignant tumors, pneumonia in children, etc. also increased. The people who need to be examined have people with sudden onset of fever, palpitations, shortness of breath, etc., or people with symptoms such as nausea, vomiting, abdominal pain, bloody stools, shock, hypotension, and hemolysis. Precautions Before inspection: 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 medical examination, you should start fasting for 12 hours to avoid affecting the test results. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. After inspection: 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 patient's blood is taken and treated to obtain red blood cells. After the red blood cells are ruptured by alkali treatment, the hemoglobin is spilled into a shadow cell. If the red blood cells remain, the RNA is deposited in the lens cells and is deposited in the shadow cells, and then clearly stained by the methylene blue. To the blue particles. The counting method is similar to that of spotting red blood cells. The percentage of alkaline colored red blood cells was calculated and the results were obtained. 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.
