Claim:
1. A wearable device, comprising: a mount for attaching the wearable device to an external body surface proximate to a vessel having a fluid flowing therethrough; a downstream clamp, positioned on the mount, that is configured to apply a downward force to the vessel sufficient to inhibit a flow of the fluid through the vessel beyond the downstream clamp, with respect to a direction of fluid flow through the vessel; an upstream clamp, positioned on the mount upstream of the downstream clamp, that is configured to apply a downward force to the vessel sufficient to inhibit a flow of fluid through the vessel beyond the upstream clamp, with respect to the direction of fluid flow through the vessel; and a detector, positioned between the downstream clamp and the upstream clamp, that can detect a response signal transmitted from a probe region of the vessel, wherein the probe region is positioned between the downstream clamp and the upstream clamp, and wherein the response signal is indicative of one or more target analytes in the vessel.
