Suppose the ammonia levels WERE high, will the damage in liver not manifest in some other parameter as well? (maybe urea, BUN, creatine, etc.?) Is
it possible that simply the
ammonia levels are high and all other parameters are normal?
Some literature on web calls the Liver Function Tests as "Dead Liver Tests", the reason being, they say, is the LFT will continue to be normal unless serious, irreversible damage is already happened in the liver.
