Urinary ketone test paper is the correct way to use the test paper submerged in the urine sample for 1-2 seconds, and then compared with the colorimetric card to read the data, the test results for the (-) number, the urine is normal and does not contain urinary ketones; if the ketones contain urinary ketones, the color of the test paper will slowly turn purple-red.
Urine ketone test paper is mainly used to detect the presence of fat metabolites (mainly ketone bodies) in urine. Before starting the test, you need to collect mid-morning urine, hold the end of the test paper in your hand, completely immerse the other end in urine, keep it out for 1-2 seconds, and then use a clean paper towel to wipe the urine on the top of the test paper, and keep it for about 1 minute to compare with the colorimetric card.
If there are no ketone bodies in the urine, the test result will be negative, that is, it will show a (-) sign. If ketone bodies are present in the urine, the color of the test strip will change from light to dark, with the darker color usually indicating more ketone bodies.
For those who have measured a large number of ketone bodies in the urine, in order to prevent the phenomenon of metabolic acidosis, it is necessary to go to the hospital in time for a detailed diagnosis and treatment.
