    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: Various modifications to a porous substrate, such as employed in lateral flow assay devices, to regulate or modify the flow rate and/or flow path pattern of a fluid through the porous substrate is described. The lateral flow assay device has a porous substrate matrix in fluid communication with a flow-rate control zone having a number of flow-rate control devices arranged as features in or on a substrate surface or laminates thereof in a body. The flow-rate control devices may include: a density gradient, porosity gradient, ion affinity gradient, micro-channels, and combinations thereof.

    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.
