Trouble at Mayo

We went straight from VBS to Mayo to get a bunch of tests done to try and determine why Amy is seizing so frequently. We're having trouble, though - they need a urine sample, and she is having so many seizures that I can never seem to catch one on the toilet (she goes in her pants during seizures). I have taped a bag onto her now (bet you can imagine about how fun that was!) and we're hoping she can go before the lab closes at 6. Prayers please?
