The stomach acid test is used to measure the quantity and acidity of stomach contents.
Alternative NamesGastric acid secretion test
How the test is performedAfter not eating for a period of time, fluid is all that remains in the stomach. This fluid can be removed via a tube inserted through the esophagus (food pipe).
To test the ability of cells in the stomach to secrete acid, gastrin may be injected just under the skin, into a muscle, or into a vein. The stomach contents are then removed and analyzed.
Another test involves insulin-induced hypoglycemia. Enough insulin is given under the skin or through a vein to cause the blood sugar to decrease. This causes the vagus nerve to stimulate the release of gastrin. After a short time, the stomach contents are removed and analyzed.
How to prepare for the testYou will be asked not to eat or drink for 4 - 6 hours before the test.
How the test will feelYou may notice some discomfort or a gagging feeling as the tube is passed through your nose or mouth, and down your esophagus.
Why the test is performedThis test may be used for a number of reasons:
Normally the volume of the stomach fluid is 20 to 100 mL and the pH is acidic (1.5 to 3.5). In some situations, these numbers are converted to actual acid production in units of milliequivalents per hour.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results meanThere is a slight risk of the tube being placed through the windpipe and into the lungs instead of through the esophagus and into the stomach. The health care provider will be sure the tube is correctly placed before continuing with the test.
If the test includes injection of insulin, there is a risk of bringing on symptoms of low blood sugar.

The pH of human stomach acid is usually between 1 and 2 in the lumen.This is not possible to say how much stomach acid present in stomach, but the pH of acid is more acidic than an HCl and Sulphuric acid.
Gastric acid determination, also known as stomach acid determination, gastric analysis, or basal gastric secretion, is a procedure to evaluate gastric (stomach) function. The test specifically determines the presence of gastric acid, as well.
The purpose of the gastric acid determination is to evaluate gastric function by measuring the amount of acid as suctioned directly from the stomach. The complete gastric acid determination includes the basal gastric secretion test.
To test for HCL you can do the Heidelberg test. It involves swallowing a capsule that will measure the acid level in your stomach and send the information back to a computer. Another option is to have blood work done.

An acid test is a rigorous test of the quality or value of something.
It is a test for uric acid. High Uric acid in he blood can lead to the formation of uric acid crystals which are responsible for the pain.
