Having had two DC outside the UK, I've been appalled by reading stories on MN about the many women who seem to have had traumatic and mismanaged births. The worst cases end up with 'bad outcomes' (which seems to be a euphemism for either mother or baby dying), but there are so many others where babies suffer birth injuries, or women suffer grave physical or psychological damage which leaves them permanently scarred - and the way these births are described so much of it might have been avoidable with better care (primarily higher staffing levels).
I've listened to a fair number of birth stories in the country where we live (from friends and baby groups etc) and only ever heard of one woman who was unhappy with the treatment she received (and in her case it was because she chose the wrong kind of birth for herself). Everyone else has seemed reasonably happy with the level of care. Obviously this is anecdotal and not in the least statistically valid, but I think antenatal care and care during labour needs to consider much more than levels of neo-natal death and still birth.
I've looked at my notes from my births, 17 and 13 years ago, and can't decipher half of them, but I definitely had a toxiplasmosis test as standard in both. I also had a rubella test in both (what are you supposed to do if you're not immune - run away from any small child you see who might be infectious?). My iron levels got checked several times. A Kell antigen test was done. Several antibody tests called Coombs tests. And a test for Treponema pallidum, which I've just seen is a diagnostic test for syphilis! Good grief, glad that one was negative. Can't see a B strep test mentioned, but that might be a more recent innovation. It sounds like a lot, but I only remember having blood taken 3 times during the pregnancy.
I think I had about 7 scans throughout each pregnancy, including the high-definition one around 20 weeks. The first scan is the first time you go to the gyn, so might be as early as 6 or 7 weeks. That's when they confirm the pregnancy, and check that it's not ectopic, and whether it's a singleton or multiple birth. Does that mean in the UK you don't find out you're having twins etc until 12 weeks?
The extra scanning means that they have a good idea of the baby's weight close to birth, and a large baby and smallish first-time mother might be recommended to have a C-section. It also means they can be sure before the birth that it's not breech (but surely this would be known in the UK beforehand too, no?). I was never worried or anxious about the scans or tests - quite the opposite, it reassured me that any anomalies would be spotted beforehand and gave the the confidence to go for a midwife-only birth in an independent birth centre.
