What's this test for?

This test is ideal if you're experiencing unexplained fatigue, weakness, pale skin, or tingling in your hands and feet that could point to a vitamin B12 deficiency or pernicious anemia. It's also useful if you have digestive symptoms or a family history of autoimmune stomach conditions. The test looks for antibodies that attack the cells in your stomach responsible for helping you absorb vitamin B12.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a normal versus abnormal range means for this antibody test. If your result is positive, next steps typically involve checking your vitamin B12 and iron levels and making dietary adjustments, while a negative result generally means no further action is needed unless symptoms persist. You can download a standard lab report from your account at any time, and if you retest in the future, you'll be able to track changes over time using the trends feature.

What's included in this test?

This test measures Parietal Cell Antibodies, with a reflex titer performed automatically if the initial screen is positive. These antibodies are proteins your immune system mistakenly makes against the stomach cells that produce acid and a substance needed to absorb vitamin B12. Detecting them helps explain why someone might be developing pernicious anemia or having trouble absorbing key nutrients, and the titer measures how much antibody is present for more detail.

How should I prepare for this test?

How can I naturally support stomach and B12 absorption health? Eating a balanced diet rich in vitamin B12 sources like eggs, fish, and dairy can help support healthy nutrient absorption. Reducing alcohol intake and managing stress may also support better stomach lining health. Staying hydrated and avoiding excessive use of acid-reducing medications, when possible, can help maintain normal stomach acid levels needed for B12 absorption.

When will I get my results?

Results for this test are typically available within about 7 days of your sample being collected. Once ready, they'll be uploaded directly to your secure online account. You'll be able to view, download, and track them anytime without needing to call or wait for a phone update.

Who should consider this test?

This test is a good option for people with symptoms of anemia such as fatigue, weakness, or shortness of breath, especially if standard iron tests come back normal. It's also worth considering if you have a personal or family history of autoimmune conditions like thyroid disease or type 1 diabetes, which are often linked to pernicious anemia. People with unexplained digestive issues or vitamin B12 deficiency may also benefit from this screening.

What symptoms indicate I may need this test?

Common symptoms include ongoing fatigue, pale or yellowish skin, dizziness, shortness of breath, and tingling or numbness in the hands and feet. Some people also notice a sore tongue, appetite changes, or difficulty concentrating. These symptoms can point to low vitamin B12 levels caused by an autoimmune reaction in the stomach.

What is pernicious anemia and why does it matter?

Pernicious anemia happens when your body can't absorb enough vitamin B12 because of an autoimmune attack on stomach cells needed for absorption. Without enough B12, your body struggles to make healthy red blood cells, which can lead to fatigue, nerve problems, and other complications if left unaddressed. Catching it early makes it much easier to manage through diet changes or supplementation.

What does a positive result mean?

A positive result means your immune system is producing antibodies against your stomach's parietal cells, which raises the likelihood of pernicious anemia or reduced vitamin B12 absorption. This doesn't automatically mean you have the condition, but it's a strong signal to look further into your B12 and red blood cell levels. Simple lifestyle steps like increasing B12 intake through diet or supplements can help while you monitor the situation.

How often should I retest?

If your first result is positive or you're being monitored for autoimmune or absorption issues, retesting every 6 to 12 months is a reasonable starting point. If you're making dietary changes or starting supplements, retesting sooner can help confirm they're working. Your trends dashboard makes it easy to see how your levels change between tests.
