How Many Labs Can Cryogenically Freeze Blood Samples?

Your optimum time would be looking at about 30 minutes. We've done tests to look at what happens to the NAD in blood samples if you just leave it on the bench or if you leave it in ice. And you can see quite rapidly after this time it does really start to degrade. The key bit is that, yeah, as long as you've got the people in the lab who know what they do in, and you have the person coming to the actual lab to get the blood taken and prepped immediately. That's kind of the missing link at the moment.
