More importantly, she said, the Australian researchers validated the test's accuracy in two additional groups: the other 817 folks in the Australian study and 74 people in a big U.S.-led study aimed at finding novel Alzheimer's disease biomarkers.
The test performed well in those situations, too, Burnham said.
CSIRO has patented the test and is talking with major companies about making it commercially available.
"It sounds like the Australians do have good clinical data" and that the markers they are testing for track with cases of the disease, said Creighton Phelps, a neuroscientist with the U.S. National Institute on Aging.
The next step is wider validation work and ensuring it can be standardized to give reliable results regardless of what lab or doctor would use it, he said.
