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
