Don't know what this patient's problem is, but I verified a Vit D of 220 on a 79y/o lady!! Wow! There wasn't a problem with the sample, or the storage, or the instrument, or the reagent.... Either she is taking way too many supplements or there is a metabolic issue. High levels of vitamin D and calcium can cause calcification and damage to the kidneys and blood vessels.
