The M:E ratio is calculated only from bone marrow differential. You count the percentage of WBCs both the immature and mature forms, in our question they were 90, then you will count the percentage of RBC immature cells, in our question it is 10, then the ratio will be 9:1, which is an increased ratio, because the normal M:E ration is 3-4:1.
