There are provided a urine testing apparatus and a urine testing method which can stabilize urine vitamins for several days and improve testing accuracy and convenience of a urine collection test of a subject. According to this urine testing apparatus, the inner wall surface of a urine collection storage container is coated with an aqueous citric acid solution or the like as a urine stabilizer. Alternatively, a dried or freeze-dried aqueous citric acid solution or the like as the urine stabilizer is stored in the urine collection storage container. On the other hand, according to the urine testing method of this invention, the aqueous citric acid solution or the like as the urine stabilizer is added to the collected urine sample, the vitamin concentration of at least 7 days after urine collection is stabilized to stabilize each urine vitamin for several days, thereby improving the convenience of the urine collection test of the subject. In particular, the urine concentrations of vitamins B can be stabilized to accurately test the nutrients lacking in the body of the subject.
