pCO2 - Arterial

Arterial Blood Gas Analysis (ABG)

Optimal range:   35 - 39 mm/Hg

The pCO2 - Arterial marker on Labcorp's Arterial Blood Gas (ABG) Panel measures the partial pressure of carbon dioxide (CO2) in arterial blood. pCO2 is an important indicator of lung function and the body’s ability to remove CO2, a byproduct of metabolism. It plays a key role in regulating blood pH through the bicarbonate buffer system. Abnormal levels of pCO2 can indicate respiratory or metabolic issues: elevated levels (hypercapnia) suggest hypoventilation or respiratory failure, while decreased levels (hypocapnia) may indicate hyperventilation or respiratory alkalosis. Monitoring pCO2 levels helps clinicians assess respiratory efficiency, acid-base balance, and potential underlying conditions such as chronic obstructive pulmonary disease (COPD), asthma, or kidney dysfunction.

Peak Combined Gas Production

Small Intestinal Bacterial Overgrowth (SIBO) 3 Hour, Genova Diagnostics

Optimal range:   0 - 19.99 ppm

A combined H2 + CH4 increase of 12 ppm or more may be suggestive of small intestinal bacterial overgrowth.

Breath analysis standards for abnormal tests are suggested if an increase of 12ppm for Hydrogen (H2), 12ppm for Methane (CH4), or a combined 12ppm for Hydrogen (H2) & Methane (CH4) is detected. Only the treating clinician is able to determine if there are additional factors that could have a material impact on the results of this analysis.

A diagnosis can only be obtained from a medical professional that combines clinical information with the results of this breath analysis.
The results of this Hydrogen (H2) & Methane (CH4) breath test should be utilized as a guideline only.
