Gastrin Blood Test


Test Code: 004390
Specimen Type: Blood

Description:

Gastrin Blood Test

This test measures levels of Gastrin in the blood.  Gastrin is a hormone which is produced by cells in the stomach.  When a person eats, the stomach releases gastrin which in turn stimulate the production of gastric acid which helps to digest food.  When this process is functioning normally, gastrin blood levels are low.  A certain type of tumor called gastrinoma can cause excess gastrin production.  The excess acid produced as a result can lead to the development of ulcers which are difficult to treat.  Gastrin may also be elevated in cases of certain types of anemia which cause damage to the cells in the stomach that produce acid.

A Gastrin test is typically ordered when someone has recurrent ulcers which do not respond to treatment along with symptoms such as diarrhea and abdominal pain.  It may also be ordered when someone is suspected of having pernicious anemia due to Vitamin B12 deficiency or a malabsorption disorder.

Turnaround for this test is typically 3-5 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Requirements:

This test requires fasting for 12-14 hours prior to blood draw.

It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample.
