<p>A test device and method of determining the presence and concentration of the total protein content, including albumin and Bence Jones proteins, in a test sample. The test device includes a test pad comprising a new and improved carrier matrix incorporating an indicator reagent composition capable of interacting with proteins to produce a visually or instrumentally detectable and/or measurable response. The new and improved carrier matrix of the test pad comprises a fibrous, bibulous substrate, such as filter paper, homogeneously impregnated with a polymerized urethane-based compound. The new and improved carrier matrix provides improved color resolution and increased sensitivity to proteins in dry phase test strip assays, thereby affording a more accurate and trustworthy protein assay of liquid test samples, such as urine. Furthermore, by utilizing a carrier matrix comprising a fibrous, bibulous substrate homogeneously impregnated with a polymerized urethane-based compound, a dry phase assay for low molecular weight proteins, such as Bence Jones proteins, can be performed on a liquid test sample.</p> |
