ABSTRACT:
The object of the present invention is to measure a concentration of protein stably at a temperature not higher than 25° C., which is a possible ambient temperature at home, and further to expand the measurable concentration range while preventing an obstruction due to a suspending particle such as a bubble and the like, using a reagent prepared by mixing an acid in a solution containing tannin, tannic acid and m-galloyl gallic acid. By mixing the reagent in a solution to be detected to opacify the solution, intensities of at least a transmitted light or a scattered light of the solution to be detected is measured, and a protein concentration thereof is determined based on the intensity. The present invention also provides a method for measuring a concentration of a solution and a method of urinalysis, wherein a protein concentration is measured after measuring an angle of rotation.
