Limitations
The 25-(OH) vitamin D form of the hormone is the principle circulating reservoir in plasma and is generally the best indicator of overall vitamin D status. Heterphillic antibodies in human serum can react with reagent immunoglobins, interfering with in vitro immunoassays. Patients routinely exposed to animals or to animal serum products can be prone to this interference, and anomalous values may be observed.
