What the Vitamin B12 Deficiency Test Can and Cannot Show

The Vitamin B12 Deficiency Test cannot by itself diagnose a condition or replace a conversation with a healthcare provider. What the Vitamin B12 Deficiency Test can tell you depends on the markers included and the quality of the sample. This blood test evaluates Vitamin B12 levels and can determine whether a deficiency is present. The Vitamin B12 Deficiency Test cannot capture factors that are not part of the panel, such as symptoms or medical history.
