We started an interesting conversation yesterday about the collection of infant DNA without parental consent. One of my readers asked some questions about use and oversight. Right now it looks like all states collect a blood spot to test for genetic diseases in babies, but what happens after the blood is tested varies by state. Here's another blogger who has some more information.
From a research perspective, I encourage you to read the comments on the link I've provided, they come from an actual researcher who shares how anonymous the information is. This makes me feel better about the idea, but I still feel that parents not the government should be the ones to give consent about the use of their baby's blood.
