Leukocyte Alkaline Phosphatase Stain (LAP)
Optimizing Laboratory Testing for Hematologic
This is a first in a series of hot topics that will address the issue of appropriate laboratory test utilization in hematologic disorders. This is a combined effort of the Divisions of Hematopathology and Laboratory Genetics with the primary focus of identifying the correct algorithmic testing approach for various hematologic diseases and secondly to demonstrate how the laboratory can and should be engaged in reducing unnecessary testing.
