This volume updates its classic predecessor in both content and format. Written by two of the respected authorities in diagnostic endocrinology, it includes detailed information on how to perform and interpret those laboratory test procedures used to confirm the clinical diagnosis of the majority of known endocrine disorders. Newly designed, it provides a standardized format that makes it easier to access complete information about the diagnosis, screening, and management of traditional and newly perceived endocrine disorders. It provides sample calculations to assist with complex formulas as well as ICD-9 codes for all procedures.
