Qi and blood detector (or qi and blood analyzer) is a kind of equipment used to measure and analyze human qi and blood level.

According to the current medical knowledge and scientific research, there is no conclusive evidence that the qi and blood detector can accurately evaluate the qi and blood status of human body.

The level of qi and blood is a complex physiological parameter, which is influenced by many factors, including physical health, eating habits, exercise degree and so on. It may not be possible to provide a comprehensive and accurate evaluation only by relying on the results of the qi and blood detector.

In the medical field, more scientific and reliable methods are usually used to evaluate the level of qi and blood, such as clinical examination, blood examination or specific medical examination.
