Maybe I've misunderstood something, but how can they know the accuracy of the test? It is the best test out there, so if it misses a diagnosis, how do they reliably catch the false negative?
It’s one of the best blood tests. There are also PET scans, lumbar punctures (spinal taps), and postmortem analyses of brain tissue.
Person has Alzheimer‘s (diagnosed by neurological assessment). Test this person with a blood test.
If the patient forgets to follow-up. Badum tss. Thanks for the layup.
Besides being a bad joke, this is in terrible taste on a thread read by people with Alzheimer's patients in their lives, and it violates HN's rules that discussion should be valuable and inspire curiosity.
