What lab values will be normal in a patient with pernicious anemia?

Serum cobalamin reference ranges may vary slightly among different laboratories, but are generally from 200–900 pg/mL. Values of 180-250 pg/mL are considered bordeline, while less than 150 pg/mL is considered diagnostic of vitamin B12 deficiency. The serum cobalamin level is low in patients with pernicious anemia.

What do red blood cells look like in pernicious anemia?

Either a lack of vitamin B-12 or a lack of folate causes a type of anemia called megaloblastic anemia (pernicious anemia). With these types of anemia, the red blood cells don’t develop normally. They are very large. And they are shaped like an oval.

What autoimmune disease causes pernicious anemia?

Is pernicious anemia hard to diagnose?

The most common symptoms of pernicious anaemia are fatigue, memory loss and problems with concentration. However, the subtle, nonspecific nature of the condition’s initial symptoms can make it difficult to properly diagnose people.

Is pernicious anemia the same as B12 deficiency?

Is pernicious Anaemia autoimmune?

Pernicious anaemia is an autoimmune condition that affects your stomach.

How do I know if I have pernicious anemia?

Your vitamin B12 level. A low level of vitamin B12 in the blood indicates pernicious anemia.

High levels of these substances in your body are a sign of pernicious anemia.

What does it mean when your red blood cell count is low?

When you don’t have enough healthy red blood cells, you have a condition called anemia. This means your blood has lower than normal hemoglobin (Hgb) levels. Hemoglobin is the part of the red blood cell (RBC) that carries oxygen to all the cells in your body.

What does a low reticulocyte count mean?

A reticulocyte (re-TIK-u-lo-site) count measures the number of young red blood cells in your blood. The test shows whether your bone marrow is making red blood cells at the correct rate. People who have pernicious anemia have low reticulocyte counts.
