Learn About Testing

Dermatology textbooks imply that there is no cure for rosacea. For up to 45% of rosacea patients, especially those with papular rosacea, pustular rosacea, and ocular rosacea, prolonged relief may be possible by taking a new direction. A simple home test kit will tell you if an alternative treatment is a reasonable choice for you. Breath tests can also be performed in your doctor’s or hospital laboratory. This test has been available since 1975; however, home testing is a recent medical development.

Information About the Breath Test

The relatively simple breath test utilizes two teaspoons of lactulose (10 grams of Kristalose) which comes in a packet to be mixed into 1 cup of water and ingested. Lactulose is a sugar that is not absorbed by the gut. Lactulose is fermented by intestinal bacteria, and the hydrogen and methane that these bacteria generate is absorbed into the blood and released by the lungs. By analyzing the amount and timing of gas in the breath, a diagnosis of small intestinal bacterial overgrowth (SIBO) can be determined.

Lactulose is most often prescribed as a laxative. Temporary side effects include diarrhea, gas, and abdominal cramping. Because lactulose is not absorbed, it will not affect diabetics.

The breath test lab charges a fee for the analysis, materials and test interpretation, which is generally billed through your insurance company. The lab requires a signed requisition from your medical provider (physician, osteopathic physician, integrative physician, chiropractor, nurse practitioner (NP, ANP), physician assistant (PA-C), or naturopathic doctor). Some labs take the responsibility for billing your insurance company but will charge for the uncovered amount.

There are several Internet sites where you can see how the breath test is performed:
