On a standard reticulocyte preparation with new methylene blue, 100 cells are counted containing blue-stained granulofilamentous material. The red blood count is 3.22 * 10^12/L, and the hematocrit is 30%. Calculate the reticulocyte production index (RPI).

Question

Quizplus · Accepted Answer

RPI = (Reticulocyte count/100) x (Hematocrit/Red blood cell count)= (100/100) x (30/3.22 x 10^12)= 3.4
