How often can the urea [13C] capsule breath test kit be reused?

The urea [C] capsule breath test kit itself is non-radioactive and very safe to use. There is no rigid requirement for the use interval. If it has been tested recently, there is no need to test it again in a short time. It is suggested that it can be used again after a long interval, as a time period for stomach examination to understand the stomach health in the next time period.
