1. A method for measuring the concentration of an analyte in sweat of a subject, comprising:
- contacting a colorimetric membrane with a skin surface of the subject, wherein at least a portion of the membrane is configured to collect a volume of sweat from the skin surface; and
analyzing the at least a portion of the colorimetric membrane to determine the concentration of the analyte in the collected volume of sweat.

Abstract
Devices, methods, and kits for measuring or otherwise evaluating the concentration of one or more analytes in a body fluid are described. The devices, methods, and/or kits may be non-invasive. In some variations, a method for measuring the concentration of an analyte in sweat of a subject may comprise contacting a colorimetric membrane with a skin surface of the subject so that the membrane collects a volume of sweat from the skin surface, and analyzing the colorimetric membrane to determine the concentration of the analyte in the collected volume of sweat.
