polychromatic red blood cells

Red blood cells are light gray blue or grayish red. It is a red blood cell that has just been nucleated but not fully mature. The volume is slightly larger than normal red blood cells, and the basophilic coloring matter in the cytoplasm is a small amount of residual ribosomes, mitochondria and the like. A small amount (about 1%) is seen in the peripheral blood of normal people. The increase reflects the active hematopoietic function of the bone marrow, and the red blood cell line proliferates vigorously. Found in a variety of proliferative anemia. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Keep a normal mindset. Normal value Normal: Occasionally. Abnormal: increased: megaloblastic anemia, proliferative anemia, hemolytic anemia. Clinical significance Increase megaloblastic anemia, proliferative anemia, hemolytic anemia. Precautions 1. If there is no prepared diluent, freshly prepared isotonic saline can also be used instead. 2. The difference between the two red blood cell counts in 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 Have a coagulopathy such as hemophilia. Adverse reactions and risks 1. Subcutaneous hemorrhage: subcutaneous hemorrhage due to less than 5 minutes of compression time or blood draw technique. 2, discomfort: the puncture site may appear pain, swelling, tenderness, subcutaneous ecchymosis visible to the naked eye.
