Finally got in to see the P/N specialist after waiting since January. He ordered the following bloodwork:

Immunoglobulin Quant. (00)
Tissue Transglutimatinase (TTG)
Free Kappa/Lambda Ratio, Serum

Anyone have an idea what he may be looking for? I've had most of the usual bloodwork before with nothing showing up, but I wondered if there's something about these three tests.

Also ordered an MRI, and asked me about back problems, family members and IBS in the same breath.

I just got the sense that he was thinking of something specific...but you know how they will never tell you before the fact if they suspect something.
