pH is the measurement of the acidity or alkalinity of a solution, or a negative logarithmic scale of hydrogen ion concentration in a solution.
Normal gastric juices are acidic in nature, having a pH of approximately 1-3. Hydrochloric acid is secreted by gastric parietal cells to kill or reduce the growth of certain bacteria and to facilitate the denaturation of proteins as they enter the gastro-intestinal tract.
The measurement of Gastrin ph can sometimes help to distinguish between Type I and Type II but is not 100% sensitive.
BackgroundI think most people have had a form of medical testing at some point in their life, i.e. the sampling and testing of blood, urine, saliva, stool or body tissue. In a nutshell, the medical staff are just measuring the content of a 'substance' and then taking a view whether this is normal or not based on pre-determined ranges.

Sometimes, abnormal results will lead to more specialist tests.In cancer, these tests are frequently called 'markers'. Most tumour markers are made by normal cells as well as by cancer cells; however, they are produced at much higher levels in cancerous conditions. These substances can be found in the blood, urine, stool, tumour tissue,…
