Abstract
The present invention provides devices and systems for use at the point of care. The methods devices of the invention are directed toward automatic detection of analytes in a bodily fluid. The components of the device are modular to allow for flexibility and robustness of use with the disclosed methods for a variety of medical applications.
Claims22
A method for detecting an analyte in a bodily fluid sample using a point-of-care system including a cartridge, an assay assembly, a fluid transfer device, and a detection assembly, the method comprising:
- positioning, via the fluid transfer device, the assay assembly at a first location that places a sample unit of the cartridge into fluid communication with the assay assembly, the assay assembly comprising a tip and an interior reaction site having thereon an immobilized binding reagent configured to bind with the analyte;
- transferring the bodily fluid sample from the sample unit to the assay assembly via the tip of the assay assembly;
- positioning, via the fluid transfer device, the assay assembly at a second location that places an addressable reagent unit of the cartridge into fluid communication with the assay assembly, the addressable reagent unit comprising a cartridge reagent;
- transferring the cartridge reagent from the addressable reagent unit to the assay assembly via the tip of the assay assembly such that a reaction occurs within the assay assembly to produce a signal indicative of the presence of the analyte in the bodily fluid sample;
- and
- detecting, by the detection assembly, the signal indicative of the presence of the analyte.
