First off, thanks for all of the GREAT info. We'll definitely push for more tests now. Below are my answers to your questions.

I never heard anything regarding thyroid during any of her pregnancies. Is that something that's routinely tested during pregnancy?

As far as thyroid testing, I'm not sure. We've already got quite a few lab results back, but I can't always match what I see in the lab result with what's on your most excellent spreadsheet. For example, your spreadsheet has spots for "TSH" and "Free T4 & T3" values. These acronyms aren't on her lab results, but she does have about several lines of thyroid results like this:
INTACT PTH IN RELATION TO CALCIUM
normal parathyroid function 10-65 NORMAL
hypoparathyroidism 65 HIGH
secondary hyperparathyroidism >65 NORMAL OR LOW
nonparathyroid hypercalcemia
