Antiparietal cell antibody test

APCA; Anti-gastric parietal cell antibody

 

An antiparietal cell antibody test is a blood test that looks for antibodies against the parietal cells of the stomach. The parietal cells make and release a substance that the body needs to absorb vitamin B12.

How the Test is Performed

 

A blood sample is needed.

 

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.

 

Normal Results

 

A negative result is normal.

Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your doctor about the meaning of your specific test results.

 

What Abnormal Results Mean

 

A positive test result is abnormal. This may be due to:

  • Atrophic gastritis (inflammation of the stomach lining)
  • Diabetes
  • Gastric ulcer
  • Pernicious anemia
  • Thyroid disease

 

Risks

 

Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.

Other risks associated with having blood drawn are slight, but may include:

  • Excessive bleeding
  • Fainting or feeling light-headed
  • Hematoma (blood accumulating under the skin)
  • Infection (a slight risk any time the skin is broken)
