B12 and folate work together in the production of red blood cells and DNA synthesis. A deficiency in either can cause a type of anemia called megaloblastic anemia, as well as neurological symptoms. Testing both together helps distinguish between the two deficiencies, which is important because treating one while the other is truly deficient can mask symptoms and cause complications.
