Slide 036

Slide 036:

Diagnosis: Acute myelocytic leukemia (AML)

Available data: 43 year- old male.
Prominent cell findings pertaining to slide 036 included myeloblasts with Auer rods, basophilic stippling, smudge/basket cells and teardrop cells. Nucleated red blood cells were evident on this slide. Laboratories failing to identify these features were assessed error points. Three hundred ninety two laboratories (87%) noted the presence of Auer rods. No error points were assigned when indicating the presence or absence of elliptocytes, schistocytes, or spherocytes. 

The responses for band neutrophils and segmented neutrophils were combined and graded as total neutrophils; the responses for myeloblasts and blasts not classified were combined and graded together.  

Four hundred sixty-three (463) laboratories passed this slide with a score of 80% or higher. Ten (10) laboratories received scores below 80%.
