Females 4.2 to 5.4 *10^12/L
Children RBC count in healthy persons varies between  3.8 – 5.5 *10^12/L
Selected Red Cell Values for the Newborn
RBC 4.4 to 5.8 *10^12/L
Note that:
Age and sex are important factors when deciding the healthy values in complete blood count test.
Female normal RBC count is less than the normal male rbc count.
ethnicity cause slight shift in upper and lower limits of RBC healthy values.
