Abstract
The invention provides a developer solution vial and methods of its use to diagnose diseases using a sampling and/or assay device, for example, for use with a lateral flow assay (LFA) device. The developer solution vial may include any container that is capable of holding developer solution. The developer solution vial is keyed to the sampling and/or assay device. The developer solution vial minimizes the amount of developer solution required for accurate fluid flow assay testing.
Claims19
A developer solution vial for use with an assay device for a point-of-care diagnosis, comprising:
- a cavity to contain a developer solution;
- and
- an elongated housing surrounding the cavity and comprising an opening extending to the cavity, and a mating portion to interface with a head of a sampling device and/or a collection pad of the assay device, the mating portion comprising, in outward order from cavity opening:
- an extraction portion comprising a rounded semi-circular cross-sectional shape that protrudes into the cavity;
- a sampling device interface portion to accept the sampling device into the cavity to elute a sample into the developer solution, and
- a seating portion to mate with a resting surface of the collection pad of the assay device or housing of the collection pad of the assay device to prevent compression of a sampling portion of the collection pad when in a resting position in the developer solution.
