Normal total Protein between 14-45 mg/dl
I had my total Protein tested and it was 21 mg/dl. Have the asymetrical sensory and motor decrement. I was probable diagnosed with Multifocal form of CIDP. With this form, a percentage of patients do not have elevated protein. The nerve damage tends to be focal or at specific locations and spots, but the limb beneath those parts are affected. Sometimes cranial involvement but there should be some evidence with the EMG and NCS to support or suggest active denervation and or demyelination to some degree.
Were you on the steroid during the time period that the LP was performed?
Any time the presention goes asymmetrical, a whole host of other possibilities exists. It would be important to determine and rule things out as necessary to get to the bottom of it so the best treatment for you can be developed.
If your symtoms are severe and a definite diagnosis has not been made, they may treat you agressively.
Sounds like your doctor is on top of it. Best Wishes
