Question
Hello doctor, I went for a test and got the following index results: H.Pylori (detects IgG and CIM factor - determines H.P in an active state) - CIM - negative - IgG - negative. May I ask if there is a possibility of HP bacteria when testing positive for H. Pyl ori? Do I need to go further? Hope the doctor responds soon!

Hello!
There are many methods to identify H. Pylori infection, the meaning of each method may not be the same.
The method of finding anti-H. Pylori antibodies in the blood if negative, you have never had H.Pylori, if positive, it only indicates that you have been infected with H. Pylori, but it cannot be determined at the time of the test. infected or not.
Some other direct methods such as Urea test, C13, 14 carbon breath test show whether you are currently infected with H. Pylori or not.
With CIM- negative; If IgG- is negative, chances are high that you are not infected with H.Pylori. However, every test method has certain errors, there may be cases of false positives or negatives. You should check again with another method to confirm, I can use a breath test.
