When examining a blood specimen on oil immersion, the red cells appear flat, large, and distorted. An average of 100 red cells is noted per oil field. Select the best course of action.
 
  a. Go to a thicker area of the specimen.
  b. Go to a thinner area of the specimen.
  c. Make a new specimen.
  d. Collect a new sample.

Question 2

In the appropriate area of a well-made blood film, two to three white cells are seen per high dry field. The automated cell counter white count on the same patient is 20.6  109/L. Select the correct interpretation.
 
  a. The estimate matches the count; report the results.
  b. The estimate does not match the count; investigate labeling error.
  c. Repeat the estimate on oil immersion.
  d. Rerun the sample through the cell counter.

Answer to Question 1

ANS: A
This area of the blood film is too far out in the featheredge for valid morphologic examination. Move further back into the slide to an area where approximately 200 RBCs/field are seen and biconcave morphology is observed. Red cells should not be overlapping and only a few touching.

Answer to Question 2

ANS: B
The white count estimate from the blood film is 4 to 6  109/L. This does not match the obtained white count of 20.6  109/L. The most likely possibility of those listed is that this is a labeling error, and that the blood film is not from the same patient as the white count. This is considered a critical error.
