Midterm Flashcards
It is young, premature, non nucleated red blood cells, contain reticular material (RNA) that stain gray blue
Reticulocytes
___________ Present in newly released blood cells for ____ days before the cell reach its full mature state.
Reticulum , 1-2 days
The 6 stages of RBC’s
Pronormoblast
Basophilic normoblast
Polychromatophilic normoblast
Orthochromic normoblast
Reticulocyte
Mature red blood cell
In 6 stages of RBC, what are the stage only for bone marrow?
Pro normoblast
Basophilic normoblast
Polychromatophilic normoblast
Orthochromic normoblast
Reticulocyte (2-3 days B.M)
Reticulocytes are visualized by _________________ (such as new methylene blue, brilliant cresyl blue, pure azure blue) forming a filamentous network of reticulum
Supra vital staining
Whole blood is incubated with ________
Supra vital staining
Causes the ribosomal and residual RNA to con precipitate with the few remaining mitochondria and ferritin masses
The vital stain
RBC’s life span
120 days
In 1 day in peripheral blood, then the BM replaces approximately ____ how many percent?
1 %
Normal value of RBC
0.5 - 1.5/100 or 0.5 - 1.5%
Absolute count
25 - 75x 10
New born (0-2 weeks)
2.5 - 6.0 %
What is the normal reticulocyte index
1-3 %
It is the actual number of reticulocytes in 1L of whole blood. This is calculated by multiplying the reticulocytes % by the RBC’s count and dividing by 100
Absolute Reticulocytes Count (ARC)
Is calculate based on a normal hematocrit of 45%
Corrected Reticulocytes Count
