Why is my Gastro+ showing wrong results?
There are a number of reasons why the Gastro+ Gastrolyzer might give incorrect readings:
- When performing a breath test, ensure that the vent hole on the back of the device is not blocked and that the mouthpieces are attached properly during tests.
- Ensure that the test is performed in a well-ventilated area and no alcohol-based products, VOC's, aerosols, or room sprays are used on or in the presence of the device as these contaminations will affect the sensor within the device.
- If the sensor has drifted, or there was a previous miscalibration, then you will need to perform a calibration reset. Please refer to the Calibration section of the Gastro+ manual for instructions.
- It may be that your test is showing high H2 cross-sensitivity. Please get in touch with your distributor to arrange a sensor replacement or service.
If the problem persists or has not been resolved by the information provided above, please contact Bedfont or your local distributor for more advice.
