The parietal cells make and release a substance that the body needs to absorb vitamin B12.AntibodiesAn antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens.

It is most often done for laboratory testing.ImageRead Article Now Book Mark Article How to Prepare for the Test No special preparation is necessary. 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. Afterward, there may be some throbbing or slight bruising. This soon goes away. Why the Test is Performed Your health care provider may use this test to help diagnose pernicious anemia. Pernicious anemia is a decrease in red blood cells that occurs when your intestines cannot properly absorb vitamin B12. Other tests are also used to help with the diagnosis.Pernicious anemiaAnemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. There are man...ImageRead Article Now Book Mark Article Normal Results A normal result is called a negative result.Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results. What Abnormal Results Mean An abnormal result is called a positive result. This may be due to:Atrophic gastritis (inflammation of the stomach lining) GastritisGastritis occurs when the lining of the stomach becomes inflamed or swollen. Gastritis can last for only a short time (acute gastritis). It may als...ImageRead Article Now Book Mark Article Diabetes DiabetesDiabetes is a long-term (chronic) disease in which the body cannot regulate the amount of sugar in the blood.ImageRead Article Now Book Mark Article Gastric ulcer Gastric ulcerA peptic ulcer is an open sore or raw area in the lining of the stomach or intestine.
