Randomized Controlled Trial
Utility, charge, and cost of inpatient and emergency department serum folate testing.
Serum folate levels are commonly ordered for multiple indications in the inpatient and emergency department settings. Since mandatory folic acid fortification in 1998, there has been a decreasing prevalence of folate deficiency in the United States. ⋯ In folic acid fortified countries, serum folate testing has low utility and poor cost effectiveness for all indications in inpatients and emergency department patients.
