I guess Dr. Goldfarb is just being thorough by ordering the spinal tap and Dr. Fred said "go for it".

When we next go to see Dr. Fred, he'll order an insulin level thing.

I will ask him about the carnitine levels.

Oh, just so you know, he has no symtoms whatever of what you indicated,
You said: "Does he get sweaty and tired, confused, trouble thinking clearly when he hasn't eaten for a while or has had a sugar load a few hours in the past? "

Nothing, nada, never happened.

So either he's from jupiter, or we'll find something out soon, hopefully??
