Patent number: 10352946Abstract: An improved qualitative or semi-quantitative diagnostic test for low levels of any analyte, such as hCG, in a biological sample, such as urine. The test comprises of a test device containing reagents for the detection of the monitored analyte and an electronic reader that measures color development at a detection area of the device. The color development is converted to an electronic or digital signal. Improvements were made to the detection process to optimize the detection of a valid fluid front, increase the detection limit without compromising the reliability and accuracy of the test system, and improve the determination of test result validity.Type: GrantFiled: January 30, 2017Date of Patent: July 16, 2019Assignee: Church & Dwight Co., Inc.Inventors: Albert R.

Patent number: 10168322Abstract: An electronically processed single-step test device for detecting the presence of a preselected analyte in a fluid. The device includes a hollow rectangular outer casing, disposed within co-joined upper and lower sections of the casing are assay material, an electronic processing system, and a display. The display is observable through a viewing window. The assay material is a sorptive material including a fluid sample application region in the form of a sample wick in fluid communication with a test strip. The test strip includes an analyte capture region adjacent to a light shield. The system includes lights which are alternately pulsed or energized over predetermined periods of time to determine if fluid test results show a marker or markers in the capture region indicative of the presence of a preselected analyte in the fluid. If so, Yes+ is displayed on the display otherwise, No? is displayed on the display.Type: GrantFiled: May 12, 2014Date of Patent: January 1, 2019Assignee: Church & Dwight Co., Inc.Inventors: Albert R. Nazareth, Francis T. Delahanty, Gregory M. Bandru, Henry J. Wieck, Stephen R. Synakowski
