Hi all you analysts and detectives out there!

Have you seen the documentary Making A Murderer (Netflix)?

There is a piece of evidence in a murder trial, where there is a suspicion that a blood spot (the defendant´s blood) has been planted at a murder scene.

The defendant argues that the planted (?) blood was obtained from an EDTA tube that the police had access to.

Therefore, the defendant would like to measure EDTA in the blood spot.

So my question is: How would YOU do this?
