DEVICE AND METHOD FOR PERFORMING A DIAGNOSTIC TEST

摘要

Devices and methods for performing a point of care diagnostic test for detecting and quantifying at least one analyte in a biological sample. The device may include an immunoassay apparatus and a holder with a variable angle stage for positioning the immunoassay apparatus relative to a light source and a detector device. In one embodiment, the device is based upon elastic light scattering, so the variation in the angle of incidence and angle of reflection are optimized to maximize signal generation due to elastic light scattering. The detector device may include a wired or wireless connection to a computer network for communicating with an electronic medical records system, uploading the amount or concentration of at least one analyte present in the sample to the electronic medical records system, or querying a decision support algorithm stored in a computer readable format. The detector device may further include an onboard interpretive algorithm.

主权项

1. A system, comprising:
an assay apparatus configured for providing a signal in response to at least one analyte of interest in a sample; a light source that (i) is positioned to illuminate the assay apparatus with at least one wavelength of light capable of interacting with the signal output of the assay apparatus; and (ii) is configured to transmit at least one wavelength of light capable of interacting with the signal output of the assay apparatus, wherein the light source is located on one side of the assay apparatus; a detector device that is positioned to capture at least one image of the illuminated signal; a holder configured to couple the assay apparatus to the detector device in proximity to the light source; and a collimating lens positioned between the detector device and the assay apparatus.
