Question
Are C13 or C14 tests equally effective? How do doctors determine which hospital uses C13 and which uses C14? Are the test results the same? My hospital only offers C13 testing. Can’t I have children within a year after the C13 or C14 test?
Answer
Both the C13 and C14 tests are highly sensitive methods used today for detecting Helicobacter pylori, with no significant differences in essence. The main difference is that C13 is an improved version of C14, non-radioactive, and safe for humans due to its stable isotope nature. It has higher sensitivity and specificity, making it more suitable for pregnant women and children. The results of the C13 test are more accurate; the sample can be stored at room temperature and protected from light for 24 hours without interference.
