Abstract
There is disclosed a slide test element and method of assay that allows for detection of analytes in biological liquids without the use of any detection reagents. The method uses NIR spectroscopy and a test element comprising a support, and a substantially constant light-path defining layer comprising a diffusely-reflecting material that is a) sufficiently porous in all directions as to allow a liquid to spread uniformly in all directions, and b) homogeneously reflects at least 95% of NIR radiation.
