About This Video
Vitamin D deficiency is rampant not just in the U.S., but worldwide, and research into vitamin D status and its effects on your health has grown tremendously in the past couple of years, showing that previously recommended levels are insufficient to reap any major health benefits.
This has led to a surge in vitamin D testing, with labs like Quest doing some 500,000 tests per month!
Unfortunately, recent developments in 2008 have made it clear that there are irregularities in the values obtained from the different testing methods. Although results from any of the three commonly used assays may be analytically accurate, they might not be clinically accurate, which is, ultimately, what matters.
Therefore, Id like to review the essentials of vitamin D testing again, and give you a vital update on how to ensure you're actually getting accurate test results.
