Ten nucleated red blood cells (NRBCs) are found in a blood film when differentiating 100 white cells. What is the corrected white blood count if the automated cell counter printed a count of 10.0  109/L?
 
  a. 0.91  109/L
  b. 9.1  109/L
  c. 91  109/L
  d. Ten NRBCs not enough to require a correction

Question 2

In the center square on one side of a hemocytometer, 100 platelets were found; 200 were found in the center square on the other side. Select the best course of action.
 
  a. Report the count as 150  109/L.
  b. Verify the count by estimating the platelet number on the blood film.
  c. Recount the hemocytometer on a phase microscope.
  d. Repeat the procedurethe two counts are not close enough.

Answer to Question 1

ANS: B
The corrected white count = (10.0  100)/(100 + 10) = 9.1  109/L. Corrections for the white count must be made when greater than 5 NRBCs/100 WBCs.

Answer to Question 2

ANS: D
The cell counts on the two opposite sides of the hemocytometers must agree within 10 of each other. Thus if the count is 100 on one side, then the other side must be no higher than 100 + (0.1  100) = 110. Because 200 exceeds this, the counts do not agreean error has been made. The dilutions must be repeated and then the new dilutions counted.
