The test typically involves taking one HCL pill with food and then increasing by one per day until a burning occurs. If burning takes place at a low dose it is thought that this is because your stomach is producing adequate HCL. And if a burning occurs at a higher dose it is thought that it is due to low levels of HCL production in the stomach.
The problem is that this is absolutely not what is really happening with this test.
