Abstract

A fluid collection device comprising a body comprising a capsule interface, and a capsule configured to interface with the body via the capsule interface and configured to hold a sample receiving chip. The sample receiving chip comprises a substrate that receives an aliquot volume of a sample fluid, wherein the substrate is operatively shaped to receive the aliquot volume of sample fluid through capillary action, and a sample region of the substrate, sized such that the volume of the sample fluid is sufficient to operatively cover a portion of the sample region, whereupon energy properties of the sample fluid can be transduced to produce a sample fluid reading.
