Abstract
A means for detecting active oxygen in the human body, which quantitatively detects the amount of active oxygen remaining in the body by applying urine to a detection paper, and is characterized by providing a means for detecting active oxygen in the human body, which detects the amount of active oxygen by submerging a test strip into urine, on which has been applied a color indicating agent that changes color by reacting with malondialdehyde (MDA) and to which has been coupled a support stick, and observing color change. The present invention can affordably and simply identify active oxygen, because the test strip changes color when simply wetted with urine and the test does not require additional technically skilled laboratory staff or expensive equipment. Also, the invention enables simple testing regardless of time and space since a specific facility is unnecessary for the test, thereby providing another advantage of general usage.
