I sent a JEEP vial for independent analysis without telling the laboratory where it came from, because I wanted an answer that could not be flattered by the question.

97.6% returned against 97.4% claimed. I am aware that a single blind submission is the strongest check an individual can make and is still one vial from one lot.

Method for anybody wanting to repeat it: order, keep the vial sealed, submit without naming the source, and compare against the lot-specific certificate rather than a catalogue figure.

Blinding the submission is the part most people skip and it is the part that makes the result mean anything.

Two tenths above the claim is noise in the right direction. The useful output is the method you have just written down.

Customs paperwork right first time is what I would add from Lagos. Dispatch speed matters much less than a form being correct.

Building on what Stellan wrote rather than answering the original question: this is also the only result whose provenance you personally know.

I am adding the method in the opening post to the circle's resources. And plainly, as on every thread here: a good independent result does not make research-use-only material appropriate for use in a person.
