Disease staging: CliniCal anD CoDeD Criteria - HCUP

GLOSSARY OF DIAGNOSTIC TERMS
The following list of diseases, conditions and diagnostic tests is provided to assist in
identifying secondary or complicating aspects of a primary disease. They are listed here
because they may occur under more than one primary disease heading. For increases or
decreases in quantitative data, the figure listed indicates 3 standard deviations from the
mean value for the analyte. This has been done to avoid minor deviations from the
reference range that might be due merely to chance rather than representing a significant
deviation due to a pathological process. For some analytes, particularly enzyme
measurements, the limits for “increased” or “decreased” are set further from the mean
values on the basis of published information. When appropriate, separate adult and
pediatric laboratory values are noted.
Bold printing indicates a reference to another citation within the glossary. These citations
may be consulted for reference ranges if they are not given in the primary citation.
Reference Ranges are from Tietz (1). Significant increased or decreased values are based
on data given for individual diseases listed in this volume or on information in references 2
and 3.
