Your health care provider will tell you if you need to stop taking any medicines. Do not stop taking any medicine before talking to your provider.Medicines that can increase the gastrin level include:Stomach acid reducers, such as antacids H2 blockers (cimetidine, nizatidine, and famotidine) Proton pump inhibitors (omeprazole, pantoprazole, and several others)Some of these medicines are available without a prescription. Discuss non-prescription medicines you are taking with your provider.Medicines that can decrease gastrin level include caffeine, corticosteroids, and the rarely used blood pressure medicines deserpidine, reserpine, and rescinnamine. How the Test will Feel When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging sensation. Afterward, there may be some throbbing or a slight bruise. This soon goes away. Why the Test is Performed Gastrin is the main hormone that controls the release of acid in your stomach. When there is food in the stomach, gastrin is released into the blood. As the acid level rises in your stomach and intestines, your body normally makes less gastrin.Your provider may order this test if you have signs or symptoms of a problem linked to an abnormal amount of gastrin. This includes peptic ulcer disease.Peptic ulcer diseaseA peptic ulcer is an open sore or raw area in the lining of the stomach or intestine.
