Would it? The recommended response to suspected concussion is the same as if you have confirmed concussion: don't drive yourself home, take a couple of days rest, don't do anything for another week or so that risks getting you another concussion, seek medical attention if things get worse. Importantly, immediate medical treatment is not generally advised. Mostly this test would be useful for ruling out concussion, e.g. letting athletes continue to play contact sports because they "just" got a bang on the head, not a concussion. Hardly a game changer.
