Cheap test for Down's babies. (2006, March). Hospital Doctor, 8. Retrieved February 21, 2008, from ABI/INFORM Complete database. (Document ID: 1011318301).

I located this article through the library’s database. Prior to 2006, prices for the CVS test had been about $300. Now CVS test is not only cheaper, but it is less time consuming and labor intensive. Currently the chorionic villus sampling is about $200 and with faster results.
