Testing For SIBO

SIBO is largely under-diagnosed because most doctors aren't aware of it. Many people don’t seek medical care for their SIBO symptoms, and testing for SIBO has proven to be difficult. Even the go-to breath test which measure levels of hydrogen and methane gas often gives false negatives.
"Unfortunately there is no perfect test. The small intestine (SI) is a hard place to get to. If we want to see or sample the SI, endoscopy only reaches into the top portion, and colonoscopy only reaches into the end portion. The middle portion, which is substantial (about 17 feet) is not accessible, other than by surgery. And stool testing predominantly reflects the large intestine (LI). Luckily, there is a non-invasive test which is commonly used in SIBO research; the Hydrogen & Methane Breath Test. Additionally there is a blood test validated to diagnose SIBO from food poisoning, otherwise known as Post-Infectious IBS." - Dr. Allison Seibecker
SIBO Breath Test
This is a 3 hour procedure that tests for overgrowth of bacteria in the small intestine measuring levels of hydrogen and methane.

Checking for IBS, Irritable Bowel Syndrome
You can do a blood test that checks for antibodies for CDT-B and the protein on the nerve cells with Quest and Commonwealth Lab.

A Test For Leaky Gut
Cyrex Labs test, Cyrex Array 2, screens for a molecule called LPS, lipopolysaccharide. LPS is an endotoxin, a toxin that comes from within a pathogenic bacteria such as H pylori E. coli, and Salmonella, which induces an extreme inflammatory response in humans. Normally LPS is blocked from entering the blood in a health digestive system. If you have leaky gut, this toxin makes it into your bloodstream. High levels of LPS indicate a leaky gut, bacterial overgrowth, and severe systemic inflammation in the body.
