This is a really intriguing use of social media by a lab to market their services! Affordable Labs in Vernon Hills, Illinois (a northern suburb of Chicago) is using Groupon to market a lab panel including cholesterol and liver function tests. Affordable Labs' website states that they are not contracted with insurance companies and are pricing their services directly to consumers, including those with high-deductible plans or no insurance at all. Disclaimer: I have no financial interest in any of this. But this is an innovative way to market lab services that deserves wider consideration.
