Methods for detecting the presence or amount of an analyte present beneath a target skin or mucosal surface of an individual are provided. The methods entail disruption of the target skin or mucosal surface, for example using a particle delivery method to provide micro-passages in the tissue. The methods further provide a resealable occlusive dressing or patch for protecting the target site from outside agents as well as maintaining hydration of the sample area. Maintaining hydration over the sampling site allows for continuous diffusion of the analyte of interest from beneath the target site to the target site. Multiple samples over time may then be taken, allowing the user to monitor for the presence of analyte over time. In a preferred embodiment, the methods are used to monitor blood glucose levels. FIG. 1 is a perspective view of resealable, occlusive dressing, with an aperture cover in a closed position.
