Question

An automated WBC count is 50.0 x 10^9/L, and the smear shows 25 nucleated red blood cells per 100 leukocytes. Using corrected WBC = measured WBC x 100 / (100 + NRBC), what is the corrected WBC?

Accepted Answer

The corrected count is 50.0 x 100 / 125 = 40.0 x 10^9/L. The correction removes the positive interference from nucleated red cells counted as leukocytes by susceptible methods.
