Gastric Acid Measurement Using Chemical Testing

The lab analyst measures the gastric specimen for total acid by chemical testing, by use of a pH meter, or both. This testing is performed on each specimen, and each specimen represents one unit. The patient may also have gastric analysis testing after a stimulation test; in that case the provider obtains fractional specimens over a 1 to 1.5 hour period for testing as described above.
