    摘要： Embodiments of the invention provide a sensor for detecting the presence of fluid in an absorbent article. The sensor may include a fluid activated battery. Fluid received in the absorbent article may connect electrodes of the fluid activated battery and cause a voltage to be generated between battery electrodes. The voltage generated between the electrodes may provide power to the sensor circuit. In one embodiment, the fluid activated battery may be configured to detect the presence of fluid in the absorbent article and the presence and/or amount of particular substances in the received fluid.

    摘要： A fluidics-based assay device for detecting the presence or quantity of an analyte residing in a test sample is provided. The device utilizes a self-calibrated magnetic binding assay format (e.g., sandwich, competitive, etc.) that includes detection probes capable of generating a detection signal (e.g., fluorescent non-magnetic particles) and calibration probes capable of generating a calibration signal (e.g., fluorescent magnetic particles). The amount of the analyte within the test sample is proportional (e.g., directly or inversely) to the intensity of the detection signal calibrated by the intensity of the calibration signal. It has been discovered that the fluidics-based device of the present invention provides an accurate, inexpensive, and readily controllable method of determining the presence of an analyte in a test sample.

    摘要： A diagnostic method and associated test kit for detecting an analyte residing in a test sample is provided. A sample membrane is utilized having a collection region and a detection region, the collection region having a known saturation volume for the intended test sample. A barrier is defined between the collection region and the detection region. The collection region is saturated with the test sample having a volume of less than about 100 microliters so that a known volume of the test sample is contained in the collection region. The barrier is removed from between the collection region and detection region of the membrane and a diluent is supplied to the collection region of the membrane to facilitate flow of the test sample from the collection region to the detection region of the membrane.

    摘要： A diagnostic method and associated test kit for detecting an analyte residing in a test sample is provided. The kit includes a housing, and a membrane disposed within the housing having a detection region and a collection region. A blood sample meter is provided having a first end for absorption of a blood sample, a filtering section adjacent to the first end that filters red blood cell components from the blood sample, and a storage section adjacent to the filtering section that receives plasma or serum from the filtering section. An opening in the housing is sized for insertion of the sample meter into the housing such that the storage section of the sample meter is disposed in fluid communication with the collection region of the membrane. The plasma or serum is transferred from the storage section of the sample meter to the collection region of the membrane for subsequent migration to the detection region.

    摘要： A method for controlling fluid flow in an assay device that employs a membrane is provided. Specifically, one or more recessed regions are formed in the membrane by applying a solvent treatment thereto. The solvent treatment is selected based on its particular dissolving capacity for the material used to form the membrane. For example, an alcohol-based solvent, such as methanol, may be used as a solvent for nitrocellulose membranes. Upon contact with the solvent treatment, a recessed region is formed that may serve a variety of different functions relating to flow control. In one particular embodiment, the recessed region may function as a metering channel that is capable of delivering a controlled volume of the test sample to a detection zone upon initiation of the assay.
