Abstract
The present invention provides a method by which UTI concentration can be measured easily with high precision and good reproducibility. The measurement is performed by adding free anti-UTI antibodies to a sample and measuring the degree of the resulting agglutination, for example, from the change in absorbance. As shown in FIG. the UTI concentration and the degree of the agglutination (i.e. the change in absorbance) are correlated. The absorbance can be measured by using a general spectrophotometer, preferably at a wavelength of 300 to 400 nm. Polyethylene glycol is preferably added to the reaction solution as an agglutination accelerator. The polyethylene glycol preferably has an average molecular weight of 2,000 to 20,000, and the concentration of polyethylene glycol in the reaction solution is preferably in the range of 2 to 10 weight %.
