The best approach to address thisproblem is to be calm before the test, take a deep breath, and exhale slowly.By exhaling slower than you normally would you give the device long enough to collect a sample.

Invalid Sample

In some cases, your device may display an “Invalid Sample” warning following atest. This problem typically occurs when the device detects an irregular breathsample following a test. If this occurs for you, take a moment and regroup.Most often this problem is the result of a failure to properly conduct the testin the first place.
