Abstract
An absorbent article that contains a lateral flow assay device for testing a bodily fluid, such as urine, blood, mucous, saliva, etc., is provided. The lateral flow assay device includes a chromatographic medium (e.g., porous membrane) that defines a detection zone that provides a signal indicative of the presence or absence of the analyte. The device may also include a control zone that provides a signal indicative of whether a sufficient amount of bodily fluid has been provided and tested. Regardless of its specific configuration, the lateral flow assay device is integrated into the absorbent article to provide a user or caregiver with rapid information about a health condition. For example, the device may be integrated into a diaper to provide information about the presence of enzymes or other compounds often encountered with a patient having a urinary tract infection. This information may provide an early warning system to allow the user or caregiver to seek additional testing and/or treatment. Alternatively, semi-quantitative or quantitative results may be derived from the test.
