This test looks for IgA antibodies which develop in the body in response to infection with the bacteria Helicobacter Pylori (H. Pylori).
H Pylori is a bacteria commonly found in the stomach. It weakens the stomach's natural protective lining making it more susceptible to damage from gastric acid. This can lead to the development of ulcers and in time, increase the risk of developing stomach cancer. There are several ways to test for H Pylori.
At Request A Test, we offer a wide variety of H Pylori testing to accommodate a variety of testing goals. An H Pylori IgG Antibody blood test looks for antibodies which the body develops in response to infection. These antibodies will typically be present if a person has had a recent or past infection and may remain detectable 12-18 months after treatment. The H Pylori IgA Antibody blood test looks for a different type of antibody which may not develop in all people. This test can help identify infection in people who only develop IgG antibodies in very low levels. An H Pylori Breath Test can be more effective for people who are determining if their treatment was successful or have had previous H Pylori infections since it does not rely on the presence of antibodies to establish if the bacteria is present. The H Pylori Stool Test looks for the presence of antigens that signal the immune system to fight infections. This test can also be effective in seeing if a person has an infection or to see if their treatment was effective.
Because not all people with H Pylori infection will show detectable levels of IgA antibodies, the results of this test may not be useful by themselves. Most people will order this test at the same time or as a follow up to a H Pylori IgG abs test.
Turnaround time for this test is typically 1-3 business days.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
The H Pylori IgA test has no fasting requirements.
