There are currently no validated biomarkers for diagnosing concussion.

“one thing is Peter is that we don't have a biomarker right now for this injury we don't there's no blood test that's ready for prime time there's no serum serum marker there's no Imaging this is not seen an MRI it's not seen on pet scan it's not seen on functional MRI it's not seen on MRI it's not seen on Meg it's not seen on EEG there's no Imaging studies right now that definitively help us with this diagnosis”

“there might be a panel of biomarkers that we look at you know but in this discussion of certain certain markers may help us but no at this point in time there's nothing I would tell you that's ready for prime time”

“even CSF fluid if you could access it no and we're doing that but no all those things are looked at people are very smart people are looking into those things and researching it but I do not have a biomarker to measure this injury”

“we have no biomarker”
