Grandma and i went to her doctor today.
As we were leaving, she says to me, "I have to get more lab work done."
Me: Oh yeah?
Gma: They don't know what is wrong with me. I will need a urine test this time.
Gma: I've never had to go into the lab to do one of those before. I'm not familiar with the procedure.
Grandma really stressed the "into the lab" part, making me think that perhaps Grandma is indeed familiar with urine tests, but has simply been doing them from home. Perhaps there is some sort of kit you can buy at the drugstore (although we've never bought one. We've bought a lot of crazy stuff, but never an at-home-urine-test.) Or maybe she does what she needs to do at home, then mails it into the lab. I don't really know. It's all speculation from here.
