Abstract
A flow assay cartridge for housing and protecting a flow assay membrane or lateral flow test strip which can be vertically stacked and is adapted for high-throughput automated lateral flow assay testing and analysis. The flow assay cartridge comprises a base and lid for receiving the flow assay membrane, and top and bottom engagement features such that two or more flow assay cartridges can be releasably adjoined in a vertical orientation such that they can be easily handled by an automated assay apparatus.
Claims19
A flow assay cartridge comprising:
- a cartridge base;
- a cartridge lid engageable with the cartridge base;
- a bottom engagement feature on the cartridge base;
- and
- a top engagement feature,
- wherein the bottom engagement feature of a first flow assay cartridge can be engaged with the top engagement feature of a second flow assay cartridge positioned below the first flow assay cartridge for releasable sliding engagement of the second flow assay cartridge to the first flow assay cartridge, the top engagement feature and bottom engagement feature comprising a rail track and at least one complementary rail guide.

(canceled)
A method of flow assay automation comprising:
- slidingly disengaging a first assay cartridge from a second assay cartridge in a vertically engaged stack of assay cartridges;
- applying sample into the first assay cartridge to begin the assay;
- and
- reengaging the first assay cartridge to another assay cartridge in the plurality of vertically engaged stack of assay cartridges by slidingly engaging the first assay cartridge to an engagement feature in an assay cartridge in the vertically engaged stack of assay cartridges, the engagement feature comprising a rail or a rail track.
(canceled)
A diagnostic test device comprising:
- a flow assay membrane;
- and
- a flow assay cartridge for receiving the flow assay membrane, the cartridge comprising:
- a cartridge base;
- a cartridge lid engageable with the cartridge base;
- a bottom engagement feature on the cartridge base;
- and
- a top engagement feature,
- wherein the bottom engagement feature of a first flow assay cartridge can be engaged with the top engagement feature of a second flow assay cartridge positioned below the first flow assay cartridge for releasable sliding engagement of the second flow assay cartridge to the first flow assay cartridge, the bottom engagement feature and the top engagement feature comprising at least one rail track and at least one rail guide.
