> Taking a vial of blood prior to a finger prick blood test could dramatically alter results. Interesting. What mechanism or phenomenon are you proposing would be happening? Why do you think sampling order has more influence than the sample method (venipuncture v. finger prick)? > Further, when the baseline (i.e. other labs) also have varying results, its fair to call into question the whole study. Why? That's an expected outcome when dealing with multiple testing labs.
