fragmented red blood cells

The schistocyte is a fragment of red blood cells or an incomplete red blood cell. They vary in size and shape, and have various shapes such as a spine shape, a helmet shape, and a triangle shape. Normal human blood smears have less than 2% of lobes, diffuse intravascular coagulation, microangiopathic hemolytic anemia, and severe globin-producing anemia. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Before taking blood, please explain whether you are taking oxygen. Normal value None (negative). Clinical significance Increased disseminated intravascular coagulation, megaloblastic anemia, hemolytic uremic syndrome, hemolytic anemia, cardiogenic hemolytic anemia, malignant tumors, severe burns, splenectomy. Precautions 1. If there is no preparation dilution, freshly prepared isotonic saline can also be used instead. 2. The difference between the two red blood cell counts during normal time should not exceed 5%, otherwise the liquid should be refilled. Inspection process (1) Take one tube and add 4 ml of the diluent. (2) Pipette 20 μl of peripheral blood with a calibrated micropipette. (3) Wipe off the remaining blood outside the pipette, blow 20μl of whole blood into the diluent, and wash the remaining blood in the pipette with the diluent, and mix immediately. (4) Wipe the counting plate and the cover glass and cover the cover glass on the counting plate. (5) Drain the mixed red blood cell suspension into the counting chamber with a pipette. (6) After standing for 2 to 3 minutes, use the high power microscope to count the cells on the red blood cell line on the four squares in the central square and the five squares in the middle, according to the principle of “no number, no number, no right”. count. The count error of each square in normal blood is not more than 10. Not suitable for the crowd A patient with hemophilia and severe clotting factor deficiency. Adverse reactions and risks Subcutaneous hemorrhage: subcutaneous hemorrhage due to less than 5 minutes of compression time or blood draw technique.
