    Doctors do not always check a CT scan unless concern for bleeding in the brain is of concern. The image of a CT scan you showed was of a chest, not a head.

    My father is a head injury survivor-head injuries are not something to mess around with! If you are doing anything that you should wear a helmet for-WEAR IT! Sadly my dad simply slipped on a slippery entryway, and whacked his head on concrete. It was an extremely long road to recovery, and he still suffers from certain impairments. Good news is that, with alot of effort and help, he has regained some ground. Neuroplasticity is amazing!

    These AI systems could be useful in double checking a human dr's analysis of a scan! I once was hospitalized with sepsis-had a CT of my abdomen right away. My results were "normal". Well-3 days of suffering and fever later, they had another dr look at the same scan, and I had a kidneystone stuck in my ureter!! REALLY bad mistake! My kidney was really infected at that point! I was pretty angry about that, but I was too sick to complain. I needed two surgeries to deal with the problem…

    Hank, Stop bad mouthing medical radiation. The odds of anyone getting cancer is about 1 in 5, no matter your risk factors. Medical radiation is a concern, but a much more minor than your assessment.

    Damn where was this both times I had a minor concussion?

    Wow Sr Foxley is awesome!

    Disappointing! Apparently, the blood test only determines one form of brain damage – concussion. But, it doesn’t determine whether or not a person has other forms of brain damage – like having the brain deprived of oxygen for a prolonged period of time. The reason this matters is because I’ve been diagnosed with both dementia and brain damage – by different doctors. It would be nice to know if I have one or the other – or maybe something else, like mental illness.

    nice test
    can used in the area that not have CT scan like villages or in poor countries like a lot of places in Africa to decrease the cost of imaging .

    Nick Collinet

    (December 7, 2018 - 10:57 am)

    With the national average cost of 1200$, varying GREATLY depending on which area you live in. But we'll just skip over the potentially political subject matter of healthcare.

    Sorry Hank, you got the concussion diagnosis a little off. The 15 point Glasgow Coma scale is for rating consciousness not soley concussions. You don't need to be knocked out to have a concussion from my experience as an Athletic Training student. Evaluation I've seen has been with a combination of but not limited to ImPACT tests, VOMS testing, and SCAT 3 or newer SCAT 5 (which does have a small section for the Glasgow scale). Also even though there is a chance of brian lesion or bleeding the vast majority of patients from sports don't need a CT unless they have severe symptoms or worsening symptoms. Also fun fact, current research is showing that making a person with a concussion sit in a dark room for days is worse than normal activity that don't exasperate symptoms. There is plenty of more info on the NATA website and the NATA concussion protocol.

    Had to explain why you would test for GFAP in the blood following a concussion on an exam just this past week. I needs you earlier!! However, I do think I said something like what you said. 🤞

    That brain damage test is amazing!I wonder what instruments is it run on and what is the procedure for it? Always exciting to get my lab hands on a new test!
