What consumer-accessible tests can and cannot determine

What consumer-accessible tests can and cannot determine — that is the question, and I have not found it answered plainly anywhere I have looked.

Something about consumer-accessible tests does not reconcile and I would like a second pair of eyes before I decide which half is wrong.

Two sources, both reputable, giving figures that cannot both be right unless they are measuring different quantities. My suspicion is that they are, and I cannot see how.

Agreed, and I will stop repeating the version of this I had been repeating.

Confirming the opening post from a second method, which matters more than confirming it from a second person.

Molecular tests: DNA or RNA tests are not applicable to peptides, which do not contain nucleic acids. Peptide-specific tests rely on protein recognition, not nucleic-acid detection.

Scoping that to what I have actually seen rather than what I have read.
