We studied and compared results of three types of urine dipsticks and the sulfosalicylic acid method using samples supplemented with various proteins. Dipsticks yield accurate results when the protein under consideration is stricted to albumin: the sulfosaliylic acid method responds to the total amount of urine protein. The sensitivities of the three types of dipsticks toward albumin are similar and are very close to the values indicated by the manufactures. The changes of urinary pH affect each of methods, but changes in slat concentration only affect results by dipstick assays. Addition of preservatives to urine samples were produced erroneous results both dipstick assays and sulfosalicylic acid method, but the refrigerated urine samples were not affected by each methods.
