Peak Methane (CH4) Production is a critical marker in NutriPATH’s 2-Hour SIBO Breath Test, used to detect methane-producing microbes in the small intestine, particularly methanogenic archaea such as Methanobrevibacter smithii. Unlike hydrogen, which is produced by bacteria fermenting carbohydrates, methane is formed when certain archaea consume hydrogen and convert it into methane gas. A methane level of ≥10 parts per million (ppm) at any point during the 2-hour breath test is considered a positive result for methane-dominant SIBO or Intestinal Methanogen Overgrowth (IMO).

The Peanut marker measures IgG antibodies to proteins found in peanuts. Results are reported as none detected, very low, low, moderate, or high. These levels reflect immune exposure and recognition rather than a true peanut allergy. Interpretation should consider symptom patterns, frequency of intake, and appropriate allergy evaluation when necessary.

The Pecan marker measures IgG antibodies to proteins found in pecans. Results are reported as none detected, very low, low, moderate, or high. These levels reflect immune exposure and recognition rather than a true tree nut allergy. Interpretation should consider symptom history, portion size, and frequency of intake.
