A indicates lower limit of normal plasma folate as used by the Second National Health and Nutrition Examination Survey (6.8 nmol/L). B indicates lower limit of normal plasma folate as used by the World Health Organization (13.6 nmol/L). Homocysteine concentrations above the dotted line (12 μmol/L) are considered elevated.
