Abstract
An immunochromatographic assay employing superparamagnetic particles to lable the target analytes. An opaque cover prevents misinterpretive readings in field situations and provides a protective surface on the porous membrane. Additional features include separability of the test strip from any backing or housing which is configured to support the strip, and that quantitative measurements of the target analytes are easily and accurately made by means of an electromagnetic reader device.
