Dermographometer
Pronunciation: der-moh-GRAF-oh-mee-ter
An instrument used to measure the pressure threshold at which dermographism (skin writing) is elicited, providing an objective assessment of symptomatic dermographism severity.
Full Definition
The dermographometer is a calibrated spring-loaded device applied to the skin surface to quantify the minimum stroking force required to produce a wheal-and-flare response in patients with symptomatic dermographism. It allows clinicians to standardise and monitor treatment responses in a way that subjective assessment cannot. Editors should note that this is a distinct tool from a dermatoscope; the two should never be confused in device-related clinical trial documentation. The term may be rendered with or without the medial 'o' (dermographometer / dermographimeter) but the former is more widely attested in British literature. It appears most commonly in allergy and urticaria clinical trial reports.
Usage
Usage note: Not synonymous with dermatoscope or dermoscope. Confirm spelling variant used consistently within a single document.
