Abstract
Aspects of the disclosure relate to demarcation templates for demarcating a test area on a test surface and for providing visual guidance to a user to precisely and accurately swab the test surface in order to determine the presence and/or concentration of an analyte of interest on the test surface. In one aspect, the analyte of interest is a hazardous contaminant. Some templates can include alignment markings around the border demarcating the test area to provide such guidance to users, and can include graphical use instructions on a removable central portion of the template. The template can be adhesive to be securely fixed to the test surface for accurate demarcation of the test area throughout sampling.
