How do you calculate cell count by dilution factor?
The formula for dilution factor (or DF for short) is as follows: DF = (final volume of cells + stain)/(initial volume of cells). For example, If you mix your sample 1:1 with AO/PI, you'll need to add 20 uL AO/PI to 20 uL cells, for a total of 40 uL. So, DF = ( 40 uL)/(20uL cells) = 2.How do you calculate the dilution factor for the cell count hemocytometer?
Dilution Factor = Total Volume (Volume of sample + Volume of diluting liquid) / Volume of sample. Total viable cells/Sample = Viable Cells/ml x The original volume of fluid from which the cell sample was removed.- 0.5 part of blood is in 100 parts of fluid or, 1 part of blood is mixed in 200 parts of fluid Thus, dilution factor for RBC counting is 200. 0.5 part of blood is mixed in 10 parts of fluid So, 1 part of blood is in 20 parts of fluid Thus, dilution factor for WBC counting is 20.
