Quoting Joshie's Mommy:" I have a scheduled c-section for March 4th but this Friday I have to do lab work at the hospital. What's ... [snip!] ... in this? For all those mommas who have experienced this can give me what to expect for this lab work. Thanks in advance."
Unless they are looking for something specific which I imagine your dr. would have told you most likely its just blood and pee to check all levels make sure your in tip top shape for the surgery no infections or anemia to worry about that kind of thing
