The “blood” level of vitamin D that we present is equal to the concentration of total vitamin D level in plasma or serum. It is measured from a dried blood spot using an LC/MS method, which is a gold standard technique. We have validated our method of measuring plasma vitamin D levels from a dried blood spot against levels in liquid plasma.
