Abstract
We examined stability of folate in 50 subjects’ dried cord blood spots stored for 9 months at −80 °C, 4 °C, ambient and humid conditions. Mean folate declined progressively, but most subjects were +/− 3 ranks of their −80 °C position. Meaningful information about relative concentrations was retained across conditions.
