PROBLEM TO BE SOLVED: To provide a noninvasive, simple and stable measurement method for active oxygen amount in a human body to solve such a problem that: in the conventional measurement method for active oxygen amount in human body, a large and expensive apparatus is not easily introduced costly and requires complicated preparations; and a measurement method for active oxygen amount using light emission or fluorescence is a surgical or invasive method since the method requires blood drawing or contacting with a body fluid such as blood by puncturing a human body with a probe.SOLUTION: The measurement method for active oxygen amount in a human body is provided in which a test gas including a hydrogen gas in a known concentration is inspired, a hydrogen gas amount in expiration after a certain period of time is obtained, and an active oxygen amount is calculated in such a way that difference between a hydrogen gas amount in inspiration and that in expiration is regarded as consumed by active oxygen in human body. |
