Methods of preparing assays and of assaying, using substantially self-contained, portable, user-initiated fluidic assay systems. Example assays include diagnostic assays and chemical detection assays. Diagnostic assays may include, without limitation, enzyme-linked immuno-sorbent assays (ELISA), and may include one or more sexually transmitted disease (STD) diagnostic assays. An assay system may include one or more fluid chambers, one or more fluid paths amongst the fluid chambers and/or between the fluid chambers, a sample portion, and/or an assay portion. The assay system may include a fluid controller system to dispense fluid from the one or more fluid chambers, and a user-initiated actuator to control the fluid controller system. The fluid controller system may be configured to dispense fluids serially, and may be configured to mix a plurality of fluids. The user-initiated actuator system may include an external user-operated trigger mechanism. The assay apparatus may include a display window to view assay results.

1. A method of preparing an assay, comprising: immobilizing a binding pair molecule on an assay substrate of a portable, user-initiated fluidic assay system, wherein the assay system includes, a portable housing having a sample portion, an assay portion, a sample fluid passage between a fluid outlet
1. A method of preparing an assay, comprising: immobilizing a binding pair molecule on an assay substrate of a portable, user-initiated fluidic assay system, wherein the assay system includes, a portable housing having a sample portion, an assay portion, a sample fluid passage between a fluid outlet of the sample portion and a fluid inlet of the assay portion, and a plurality of fluid chambers, each of the plurality of fluid chambers having a fluid chamber outlet,a fluid controller system separating the plurality of fluid chambers and movably disposed within the housing to align each of the plurality of fluid chamber outlets a with corresponding fluid path to one or more of another one of the fluid chambers, the sample portion, and the assay portion, anda user-initiated mechanical actuator coupled to the fluid controller system;providing a dilutent solution to a first fluid chamber of the assay system;providing a labeled secondary binding pair molecule solution to a second fluid chamber of the assay system; andproviding a wash solution to a third fluid chamber of the assay system. 2. A method of assaying, comprising: receiving a sample within a portable, point-of-care, user-initiated fluidic assay system, wherein the assay system includes, a portable housing having a sample portion, an assay portion, a sample fluid passage between a fluid outlet of the sample portion and a fluid inlet of the assay portion, and a plurality of fluid chambers, each of the plurality of fluid chambers having a fluid chamber outlet,a fluid controller system separating the plurality of fluid chambers and movably disposed within the housing to align each of the plurality of fluid chamber outlets a with corresponding fluid path to one or more of another one of the fluid chambers, the sample portion, and the assay portion, anda user-initiated mechanical actuator coupled to the fluid controller system;fluidizing the sample, under control of the user-initiated mechanical actuator;contacting a binding pair molecule with the fluidized sample, under control of the user-initiated mechanical actuator;contacting the binding pair molecule with a labeled secondary binding pair molecule solution, under control of the user-initiated mechanical actuator;washing an assay substrate within the assay system, under control of the user-initiated mechanical actuator; anddisplaying a result of the contactings.
