Diagnostic test system and method utilizing a closure/sample dispensing mechanism to dispense a sample subvolume for testing
A diagnostic test system, including: a diagnostic test assembly and a diagnostic test apparatus to perform a test on a biological or environmental sample; the diagnostic test assembly includes: a sample preparation reservoir to receive the sample into a sample preparation fluid, such that a swab carrying the sample can be used to stir the preparation fluid and to wash the swab; a sample dispensing mechanism for insertion into the sample preparation reservoir; a closure to seal the sample preparation reservoir; at least one diagnostic test reservoir coupled to the sample preparation reservoir; and at least one seal between the sample preparation reservoir and the diagnostic test reservoir to prevent fluid movement between the respective reservoirs; wherein the sample dispensing mechanism is operable to disrupt the seal to allow sample fluid to enter the diagnostic test reservoir from the sample preparation reservoir, and to dispense a predetermined amount of fluid.
MICROPOROUS SUBSTRATE FOR USE IN A DISPOSABLE BIOASSAY CARTRIDGE
A microporous substrate for detection of surface bound target analyte molecules includes a microporous substrate material having opposed surfaces and tapered micropores extending through the substrate with the micropores having wider openings on one side of the substrate compared to the other side. The micropores have bound therein analyte specific receptors complementary to the target molecules. When a liquid sample containing the target analyte molecules with optical probes attached to the target molecules is flowed through the substrate, they bind to their complementary analyte specific receptors and emit light. This microporous substrate structure gives an increase in the collection efficiency of light emitted from optical probes when the light is detected by a light detector spaced from the side of the microporous substrate facing the larger micropores openings compared to a light collection efficiency of light emitted from the optical probes when the micropores are straight and not tapered.
