Potential errors in the measurement of total protein in male rat urine using test strips

Abstract
Widely differing results were obtained for urinary protein determinations in male rats using 2 test strips and a quantitative Coomassie Blue sodium dodecyl sulphate method. A comparison of the sensitivity of the protein methods with respect to rat albumin and α2U globulin was made; both test strips were found to be relatively insensitive to the presence of α2U globulin. Resultant limitations of test strips in monitoring adult male rat urine protein concentrations are discussed.
