Without sufficient levels of B12, the body cannot produce red blood cells, which leads to the development of anemia.

  • Sample Type: Blood
  • Results: 2-10 days
  • Age: 18+

Intrinsic factor is a protein that binds with vitamin B12 and allows it to be absorbed by the body during digestion. In people with pernicious anemia, the immune system produces antibodies against internal factors. This interferes with the normal process through which the body absorbs vitamin B12. Without sufficient levels of B12, the body cannot produce red blood cells, which leads to the development of anemia.

No fasting required. Samples should not be collected from a patient who has received Vitamin B12 injection therapy within the last week.
