The enormous array of laboratory tests can indeed confuse the clinician, and some guidance is desirable. The author has tried to provide such a guide. He discusses principally chemistry and hematology and has arranged his presentation alphabetically by blood components. Thus, the first six chapters take up disorders of alkaline and acid phosphatase, bilirubin, calcium, electrolytes, glucose, and hormones.

For example, under glucose there are classified disorders of intake, absorption, production, storage, excretion, regulation, and "miscellaneous," with one or more diseases characterized under each. Diabetes comes under "miscellaneous" and receives about as much space as "idiopathic steatorrhea" (disorder of absorption).
