A Sudoscan is a fast, painless, non-invasive test that quantifies your level of possible nerve degeneration or peripheral neuropathy.
ABI, also called Ankle-Brachial Index test, is a test which compares the blood pressure in your ankles to the blood pressures in your arms. It is a safe and painless test that helps your physician determine if your legs are getting the proper amount of blood supply and predicting the severity of peripheral arterial disease (PAD). Patients with history of cardiovascular conditions, diabetes, smoking, obesity, and pain or loss of feeling in the arms, legs, or feet may benefit from an ABI.
The hydrogen breath test is a test that uses the measurement of hydrogen in the breath to diagnose several conditions that cause gastrointestinal symptoms. In humans, only bacteria - specifically, anaerobic bacteria in the colon - are capable of producing hydrogen. The bacteria produce hydrogen when they are exposed to unabsorbed food, particularly sugars and carbohydrates, but not proteins or fats. Although limited hydrogen is produced from the small amounts of unabsorbed food that normally reach the colon, large amounts of hydrogen may be produced when there is a problem with the digestion or absorption of food in the small intestine, which allows more unabsorbed food to reach the colon.
Large amounts of hydrogen also may be produced when the colon bacteria move back into the small intestine, a condition called bacterial overgrowth of the small bowel. In this latter instance, the bacteria are exposed to unabsorbed food that has not yet had a chance to completely traverse the small intestine to be fully digested and absorbed. Some of the hydrogen produced by the bacteria, whether in the small intestine or the colon, is absorbed into the blood flowing through the wall of the small intestine and colon. The hydrogen-containing blood travels to the lungs where the hydrogen is released and exhaled in the breath where it can be measured.
Pulmonary function tests (PFTs) are non-invasive tests that show how well the lungs are working. The test measures lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders.
