Not sure that you’d get reactions from large subunits if they fold differently than the full spike—but my biochemistry/immunology isn’t enough to be sure about how this would work.
The marketing material for the test kit has a long description of steps they took to get the same conformation. It’s still marketing material, so I don’t trust it 100%, but there’s at least a plausible story that it should be the same.
