Abstract
The present invention is directed to non-instrumented assays giving quantitative and/or qualitative results. In one embodiment, the present invention is directed to a process and kit determining analyte in a sample wherein the solid support has a contact zone and binder distributed and immobilized throughout the solid support. A sample and a tracer are added to the contact zone and a visible zone is obtained. In another embodiment, the present invention is directed to a process and test wherein the solid support has two contact zones and the binder is not immobilized on the solid support. In this embodiment, the binder is mobile and is added to the second contact zone. At the same time, sample and a tracer are added to the first contact zone. A visible zone is obtained.
