Test strips and method for extending sample flow path in lateral flow assays

Abstract

The present disclosure provides a method of extending the path of a biological sample flow in a lateral flow assay on a test strip including a membrane. The method includes arranging the membrane in a helical shape in a test strip. The helical shape extends the flow path increasing interaction time between the biological sample and binding reagents on the membrane as the sample flows through multiple turns of the helix. Further, a lateral flow assay on the test strip including a membrane disposed on a surface of the test strip in a helical shape is provided. The helical shape extends a path of a biological sample flow through the membrane.
