Gastrin

Results continued...

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.

Gastrin 1
Adults:

Less than 100 picograms per milliliter (pg/mL)[less than 48 picomoles per liter (pmol/L)]

Children:

10–125 pg/mL (5–60 pmol/L)

 

Many conditions can change gastrin levels. Your doctor will talk with you about any abnormal results that may be related to your symptoms and past health.

High levels

High gastrin levels may be caused by:

Low levels

Low gastrin levels may be caused by hypothyroidism.

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

  • Eating before the test.
  • Drinking caffeinated beverages or alcohol right before the test.
  • Taking some medicines. Examples of medicines that can affect results include medicines that reduce stomach acid (such as Pepcid, Prilosec, or Zantac) and medicines or supplements that contain calcium (such as Tums or a daily vitamin). Make sure your doctor knows about all the medicines, herbs, and supplements you take.
  • Having had stomach ulcer surgery or a small bowel resection. Increased gastrin levels also occur in medical conditions such as kidney failure, rheumatoid arthritis, and cirrhosis.
