Dixie,
If you don't have any confidence in the ability of science to collect representative samples....then next time you go to the Doctor for a blood test, make sure you insist they take all of your blood.
Because, a tiny representative sample, comprising less than 1% of your total blood, is not sufficient to prove or provide a conclusive chemical analysis of your blood.
Make sure they drain you, bro'.
