Vitamin D deficiency is common in many populations, particularly in individuals at higher latitudes, during the winter months, and in those with limited sun exposure. Vitamin D supplementation and increased sun exposure are sufficient for most healthy individuals.
The laboratory test is appropriate in high risk individuals when the results are aimed at the institution of a more interventional therapy, as for example in cases of osteoporosis, chronic kidney disease, malabsorption, and obesity. Routine screening of healthy infants, children, and adults (including pregnant women) for vitamin D deficiency is currently not recommended.
It is recalled that current methods of vitamin D determination may give different results for the same sample and that there are limitations in the laboratory methods used.
