The ease with which a complete blood count (CBC) may be obtained also leads to frequent observation of values which fall outside the reference range. Such perturbations may be the sign of something as ominous as acute leukemia, or as inconsequential as the common cold. That such changes might generate considerable anxiety, both for patients and providers, is not surprising given the plethora of life-threatening diseases that often manifest classic CBC findings.This ever-increasing dependence on labs as screening tools generates a seemingly endless supply of “abnormal” results, often triggering hematologic consultation. Electronic medical records (EMRs), as repositories for this ever-growing data, serve as invaluable tools in evaluating the chronicity and trend of such findings.In this chapter, we outline our approach to dealing with these common queries. The individual epidemiology, pathogenesis, and treatment of such disorders are covered comprehensively and with clarity within their corresponding chapters and are not repeated here. Rather, what we describe is our thought process in approaching such questions and narrowing the broad differential to that which is reasonable and probable.
