RNA staining

During the development and maturation of blood cells, the content of ribonucleic acid has obvious regular changes. Ribonucleic acid plays an important role in protein synthesis and is closely related to the cell's ability to divide and proliferate. It is an important substance in cells. After the action with the special dye solution, the content can be observed. Basic Information Specialist classification: growth and development check classification: genetic testing (DNA) Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: Negative is a normal result. During the development and maturation of blood cells, the content of ribonucleic acid has obvious regular changes. The nucleus and cytoplasm of the original stage are rich in ribonucleic acid, and the amount of ribonucleic acid is reduced in the infancy stage, and disappears or disappears completely in the mature stage. Positive: Abnormal results reduce bone marrow hyperplasia, hematopoietic tissue ribonucleic acid content is significantly reduced, such as aplastic anemia, ribonucleic acid content can be reduced. When the hematopoietic tissue is proliferated, the ribonucleic acid content of hematopoietic cells is significantly increased. Such as megaloblastic anemia. Tips: After 8 pm on the day before the medical examination, you should start fasting for 12 hours, so as not to affect the test results. Normal value During the development and maturation of blood cells, the content of ribonucleic acid has obvious regular changes. The nucleus and cytoplasm of the original stage are rich in ribonucleic acid, and the amount of ribonucleic acid is reduced in the infancy stage, and disappears or disappears completely in the mature stage. Clinical significance Abnormal results: When the bone marrow hyperplasia is reduced, the ribonucleic acid content of the hematopoietic tissue is significantly reduced, such as aplastic anemia, acute radiation sickness, paroxysmal nocturnal hemoglobinuria and other diseases, the ribonucleic acid content can be reduced. When the hematopoietic tissue is proliferated, the ribonucleic acid content of hematopoietic cells is significantly increased. For example, juvenile red blood cells of megaloblastic anemia and hemolytic anemia, immature cells of various types of leukemia, mature granulocytes in infection, Hodgkin's cells, megakaryocytes in thrombocytopenic purpura, and the like. People who need to be examined should be examined if they are prone to infection with sore throat, bronchitis with headache, low fever, mouth pain and rash, swollen lymph nodes, easy bruising or bleeding. Positive results may be diseases: aplastic anemia, thrombocytopenic purpura, pediatric paroxysmal nocturnal hemoglobinuria 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 Inspection process: After blood collection, observation by a microscope is performed by various cell staining methods. Not suitable for the crowd Taboo people: No. Adverse reactions and risks It does not generally cause special complications and hazards.
