A gastrin test measures the level of the hormone gastrin in the blood. Results are usually available in 1 to 2 days.
The normal values listed here—called a reference range—are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what’s normal. Your lab report should contain the range your lab uses. Also, your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values listed here may still be normal for you or your lab.
Normal values may be higher in very young children and older adults.
