String test may improve diagnosis, treatment of ulcers: Nobel laureate

The other end of the string travels through the digestive system, collecting samples of mucus and bacteria. The string is removed and analysed. "The string test and quantitative PCR (qPCR) confirm the diagnosis and tell us about the best antibiotic for treatment," he said. "Research on the test is still ongoing, but we know it is showing some promise," he said. The test, if proven, may improve the diagnosis and treatment of ulcers.
