The 8-item NHANES pocket smell test: Normative data.

This study provides normative data useful for interpreting scores from the Pocket Smell Test (PST), a brief "scratch & sniff" neuropsychological olfactory screening test comprised of 8 items from the 40-item University of Pennsylvania Smell Identification Test (UPSIT). We combined 3,485 PST scores from the 2013 to 2014 National Health and Nutrition Survey (NHANES) of persons 40 years of age and older with equivalent PST items extracted from an UPSIT database of 3,900 persons ranging in age from 5 to 99 years. Decade-related age- and gender-adjusted percentile normative data were established across the entire age spectrum.
