How is cobalamin deficiency diagnosed?
The serum cobalamin assay is the primary diagnostic test for cobalamin deficiency. It appears to be an excellent screening test since most patients with clinically confirmed cobalamin deficiency have low levels.
Is B12 deficiency serious?
Vitamin B12 deficiency can lead to serious complications such as nerve damage, anemia and fatigue, which is why those at risk should add a high-quality B12 supplement to their diet ( 2 ).

Folic acid is found in leafy greens and many foods are fortified with folic acid, making deficiency uncommon. Deficiency mainly results in megaloblastic anemia, without manifestation of hair loss.
Does folic acid deficiency cause neurological symptoms?
The neurologic manifestations of folate deficiency overlap with those of vitamin B12 deficiency and include cognitive impairment, dementia, depression, and, less commonly, peripheral neuropathy and subacute combined degeneration of the spinal cord.
How does cobalamin deficiency cause anemia?

Why is MCV high in B12 deficiency?

What are the rarest disorders of cobalamin transport?
The most clinically significant among the rare disorders of cobalamin transport is transcobalamin II deficiency, which causes megaloblastic anemia in infancy and is associated with normal cobalamin concentrations.
