Latest Patents
Joanne Zeng holds a patent for a test strip that includes an integral specimen flow-retarding structure. This innovative test strip comprises a first layer and an overlying differential flow-retarding layer that reduces the fraction of a component of a liquid specimen that percolates through it. The design features an inert backing, preferably with an aperture, that overlays the flow-retarding layer. Specifically, for blood specimen testing, the flow-retarding layer is made of glass fibers that effectively reduce the fraction of red blood cells in the percolate, allowing primarily plasma to pass through. The first layer contains chemicals that react with components of the plasma, such as glucose, resulting in a visually measurable reaction. This design minimizes visual interference from the red color of whole blood, enhancing the clarity of the test results.
