Effective December 4, 2024, breath methane will be added to Bacterial Overgrowth, Breath Test (LAB3295) and Lactose Intolerance, Breath Test (LAB3097). As a result, the test will include both breath hydrogen and methane. Methane is being added as a small percentage of patients who have either bacterial overgrowth or lactose intolerance will not produce hydrogen when challenged during the test. These patients are considered methane-producers.
In addition, the collection time point of 150 minutes is being eliminated to align with system-wide standards.
