Abstract
A sample testing apparatus (100) for use in measuring an analyte in a sample (105) is disclosed. The apparatus includes a sample well (104) for receiving the sample. A solid analyte binding agent (160) is disposed in the sample well. The apparatus further includes a mixing device (156) for mixing the sample with the solid analyte binding agent and a valve (129). The valve is configurable between a closed position for impeding flow of the sample from the sample well and an open position for releasing the sample from the sample well. The apparatus additionally includes a membrane (118) for receiving the sample once released from the sample well, the membrane having a capture reagent (164) adapted to interact with at least one of the analyte, the analyte binding agent, or a complex thereof, to aid in determining the amount of the analyte in the sample.
