Indications for Vitamin B(12) Therapy: A retrospective study.
A retrospective chart audit was undertaken to determine the clinical reasons for vitamin B(12) therapy in family practice. Abnormal laboratory tests and symptoms were the most common reasons for initiating therapy. The high proportion of cases with little supporting evidence of B(12) deficiency suggests that other factors influence treatment decisions.
