tested — not confirmed— Real instrument/substrate; the diagnostic or therapeutic interpretation failed testing; a correct reinterpretation remains open (§0.1-B).
Same substrate as EAV — a real electrodermal measurement — with an ampoule-in-circuit allergy/toxin interpretation that failed testing. Instrument real; interpretation not confirmed.
Origin & lineage
Schimmel's 1970s modification of Voll's method.
Claimed mechanism
Coded ampoules placed in an EAV-type circuit 'detect' allergy or toxins.
Plausibility
Implausible — operators perform no better than chance under blinding; the electrodermal substrate is real.
