clinical significance , calculation and dilution of RBC count

dilution of RBC, calculation of RBC, clinical significance of RBC

* Calculation of RBC count 
 
       No.fo cell count.         dilution
=        Area               ×     Depth of neubar 
                        
 
 
=      No.of cell count.     ×     200
               1/5                               0.1
 
 
=       No. Of cell count ×5×200×10
 
=.   . No. Of cell count ×10000  cells/ cu mm
 
*   Explain the dilution of RBC count
= Diluting fluid  +  blood sample
                   Blood sample
3.98 ml + .002ml.
           .002ml.
Change in to micro litre  1 ml = 1000 microlitre
 
= 3980+20
          20
= 4000             =   1: 200       prooved
     20
 

6.clinical significance 

Erythrocytosis :-Increase total RBC count is observed in the condition such as:-

1.Haemoconcentrarion
2.Due to burns
3.Dehydration
4.Polysythemia
                    ETC….
Erythrocytopenia :- decrease total RBC count is observed in the condition such as:-
1.anemia
2.chronic heart’disease
3.lungs infection
