A method by which a user terminal performs urinalysis, according to one embodiment of the present invention, comprises the steps of: (a) photographing a urine test strip to which urine is applied, so as to generate a test image; (b) extracting, from the test image, an RGB value for each of a plurality of pad areas corresponding to each test item area of the urine test strip, so as to generate a first RGB value; and (c) and generating a first ratio value through the first RGB value and a specific gravity RGB value extracted from the pad area of a specific gravity from among test items, and comparing a second ratio value, which is the ratio between a calculated specific gravity and each test item, and the first ratio value through a standard colorimetric table so as to calculate a numerical value for each test item, wherein the standard colorimetric table defines all colors that the pad area corresponding to each test item can express. |
