That's interesting. I'm 38 and my doctor hasn't mentioned any special end-of-pregnancy testing. As PPs mentioned, it must be an NST since genetic testing is done much earlier. I would ask your doctor why they think it's necessary - I don't think it's standard in most offices to do one unless they suspect a problem, even if we are AMA moms. It seems like it's just extra cost to you and your insurance company for no good reason (and AMA is not really a good reason to do an NST IMHO). You will also I'm sure be doing the gest. diabetes test around 28 weeks, but everyone has to do that regardless of age. Anyways, yeah if I were you I would question this one. Best of luck!
