Hi Razorbackfan,
I'm sorry I don't know much at all about kappa free light chains but if you can do a Google search, you might be able to find out more. I looked up a couple of links on it but the information there was pretty technical, I thought. Maybe someone else here can provide more useful information.

Good luck with the video visit. If it's Facetime, that seems fairly easy. Even I have been able to get along with it, using an older iPad2. I've glanced over the Zoom setup but not tried it. It seems to have more bells and whistles.

So far my doctors have been using phone visits. Maybe your doctor would be willing to do that if you don't feel up to whatever video arrangement is being used.
