N-type calcium is the same as VGCC-N? I have tested VGKC, VGCC, CASPR2 and LGI1. But VGCC-N is something else?
I'm so sorry for the delayed reply and haven't been on PR in a few days. I just replied to your PM and please let me know if I missed anything that you asked.
My understanding is that the Voltage Gated Calcium Channel (VGCC) autoantibodies that can be tested by a commercial lab are the P/Q type and the N type. Some labs lump several things together while others break down each individual autoantibody test.
If you want to be certain, I would try to get a break-down of each autoantibody that you were tested for, and for the VGCC Autoantibodies, it should specify the P/Q type and the N type. In my case (since 2016) I am consistently positive for the N type but negative for the P/Q type.
After being sick for 17 years if it was LEMS, I figured I would not be able to climb stairs or pick my 80lb dog up and into the truck.
From my personal experience, and from talking to many people with LEMS in a private FB group, I agree with you that climbing stairs would be very difficult and you would not be able lift 80 lbs if you had LEMS. Although I realize that there are exceptions to everything out there!
I consider myself truly to be in remission from LEMS yet climbing stairs and lifting heavy things are still both very difficult for me. But at my most severe (prior to treatment), I could not squeeze shampoo out of the bottle, open a door, or cut food with a knife.
