Polychromatic red blood cells?
summary
The red blood cells were light gray blue or gray red. It is a kind of newly denucleated but immature red blood cell. The volume of red blood cells was slightly larger than that of normal red blood cells, and the basophilic coloring substances in the cytoplasm were a small amount of residual ribosomes, mitochondria and other components. A small amount (about 1%) can be seen in the peripheral blood of normal people. The increase reflects the active hematopoietic function of bone marrow and the proliferation of red blood cell line. It can be seen in all kinds of proliferative anemia.
Polychromatic red blood cells?
Polychromatic red blood cell examination process 1) take one tube and add 4ml diluent. 2) Peripheral blood was aspirated with a calibrated micropipette for 20 minutes μ l。 3) Wipe off the remaining blood on the outside of the suction tube and remove 20 μ Blow the whole blood into the diluent, wash the remaining blood in the pipette with the diluent, and mix it immediately. 4) Clean the counting plate and cover glass, and cover the cover glass on the counting plate. 5) The mixed red blood cell suspension was aspirated with a dropper and filled into the counting room（ 6) After standing for 2-3 minutes, count the red blood cells in the four corners of the central square and the five central squares with high power microscope, and count the cells on the side line according to the principle of "counting up but not down, counting left but not right". The counting error of each square in normal blood is not more than 10.
If no diluent is prepared, fresh isotonic saline can be used instead. 2. In normal condition, the difference between the two red blood cell counts should not exceed 5%, otherwise the liquid should be refilled for counting.
The red blood cell is light gray blue or gray red. It is a kind of newly denucleated but not fully mature red blood cell. Its volume is slightly larger than that of normal red blood cell. The basophilic coloring material in the cytoplasm is a small amount of residual ribosome, mitochondria and other components. A small amount (about 1%) can be seen in the peripheral blood of normal people. Its increase reflects the active hematopoietic function of bone marrow and the vigorous proliferation of red blood cell line. It is found in various kinds of proliferative anemia
