Abstract

In order to investigate the reliability of palpatory examination procedures, some form of skin marking which will not confound repeated tests would be advantageous. This communication introduces a commercially available marker pen containing a writing fluid which is visible only under ultra-violet (UV) light, and illustrates its use by means of two studies of palpatory reliability. The marker pen (in conjunction with a portable battery-powered UV light source) was found to be satisfactory for 'blind' repeatability studies; earlier skin marks were invisible on subsequent examinations, were not corrupted by further palpation, and showed up clearly under UV light. The system described is inexpensive, simple to use, and facilitates reliability studies of palpatory techniques.
