The SIBO 3-Hour Test from Genova Diagnostics is a diagnostic tool designed to assess for Small Intestinal Bacterial Overgrowth (SIBO). SIBO is a condition where excessive bacteria are present in the small intestine. This can lead to various symptoms like bloating, gas, abdominal pain, diarrhea, and nutritional deficiencies. The SIBO 3-Hour Test is specifically designed to detect this condition by measuring the levels of hydrogen (H2) and methane (CH4) gases in the breath, which are byproducts of bacterial metabolism.
