The Parietal Cell Antibody with Reflex to Titer Test checks your blood for antibodies that may attack the stomach’s acid making cells. You may also hear it called a gastric parietal cell antibody test, anti parietal cell antibody, or PCA IgG. If your provider ordered this, you can book at participating labs on LabFinder.
Some centers list it as a parietal cell antibody screen with reflex titer or PCA test. It looks for antibodies linked to autoimmune gastritis and low vitamin B12 levels. If the screen is positive, the lab measures a titer to show how strong the antibody level is.
Common reasons: unexplained anemia or low B12, numbness or tingling that may be due to B12 lack, long term stomach upset or inflammation, concern for pernicious anemia, or a history of other autoimmune conditions. Your provider may order this with an intrinsic factor antibody test and a vitamin B12 level for a fuller picture.
You will check in, confirm your order, and a phlebotomist will draw a small tube of blood from your arm. The blood draw takes about a minute. Plan for about 10 to 20 minutes at the site, including check in and wrap up. A small bandage is placed and you can go about your day.
Yes, this is a quick, routine blood draw and is considered very safe. You might feel a quick pinch, notice a small bruise, or feel a little lightheaded for a moment afterward, but those effects usually fade quickly. Be sure to tell the staff if you take blood thinners, have a bleeding disorder, or if you have fainted during blood draws before. They will take extra care to keep you comfortable. Let the team know if you recently had a vitamin B12 shot, since this can be helpful context for related testing.
No fasting is typical: eat as you usually do unless your doctor says otherwise. Stay hydrated: drinking water can make the draw easier. Share medicines and supplements: bring a list, including acid reducers like PPIs and any B12 shots. Wear short sleeves: this speeds up the draw. Always follow any instructions from your provider or the lab and bring prior results if you have them.
Pernicious anemia, autoimmune gastritis, vitamin B12 deficiency, chronic stomach inflammation, and nutrition problems linked to poor B12 absorption. Results are only one piece of the puzzle. Your doctor will review them with your history and symptoms before advising next steps.
You can compare locations, see time slots, and book online at participating labs. It is easy to search for a convenient location in your area or by city or ZIP. Cost and insurance: coverage varies by plan and provider, so please check your benefits or ask the lab when you book.
