The SIBO kits dispensed from the NUNM SIBO Lab contain Lactulose which is a legend drug regulated by the FDA. Kits can only be ordered by practitioners who have prescribing rights for legend drugs.

Interpreting Results

There is no universal standard for interpreting breath test results. The NUNM SIBO Lab bases our reports on the manufacturer’s guidelines for reporting whether or not SIBO is suspected. These guidelines should be used to assist providers in further interpreting the results based on their clinical expertise.

Detection of SIBO using the lactulose breath test is done by measuring the levels of hydrogen (H2) and methane (CH4) gases using a BreathTracker SC analyzer (a machine manufactured by Quintron). These gases are produced by bacteria in response specifically to the lactulose or glucose substrate.

SIBO Testing

The SIBO Lactulose Breath Test used by the NUNM SIBO Lab is manufactured by Quintron. Breath tests for SIBO have been reported to have greater reliability and acceptability than the blood test.
