I'm strangely interested in how HypoT was recognised before THE blood test (did you see the pinch test?) well, here's one about slow reflexes
I've had these 'hammer' tests on various joints but now I think they didn't really know what they were doing (or nerve conduction tests either! I thought they were testing for MS?), but this chap seems to know.... (do feel a bit sorry for the lad 'tho) J
