(A) Correlation between platelet counts and Ln (percentage of F cells) in 26 individuals in this study. (B) Correlation between Ln (percentage of F cells) and erythrocyte counts in 850 healthy female adult whites. (C) Correlation between erythrocyte mean cell volume (MCV) values and Ln (percentage of F cells) in 850 healthy female adult whites.
