Editor's Notes
- #43 Thanks to these studies and national headlines praising its apparent cancer-fighting properties it appears many people now consider vitamin d their wonder drug and are rushing to labs to have their levels tested. The patients requesting these tests through their physicains represent an increasingly health conscious-public. These patients want greater control over managing their own health, they have greater access to information related to health promotion and illness prevention, and there are a growing number of media stores that address their demand for news and information about personal health issues. Spikes are often seen when these three drivers come together – as in the case of vitamin d There is no count on how many people get their vitamin d checked. But at testing giant LabCorp, the volume of vitamin D tests doctors order has, on average, doubled every year for the past four. So far this year, test orders are up another 90%. At competitor Quest Diagnostics, the volume of D tests approximately tripled between may 2006 and last may. http://www.virginiahopkinstestkits.com/vitamindtest.html http://abcnews.go.com/video/playerIndex?id=5563319 Vitamin D video
