do you know what they were for? What does it say on the form?
It may be they were the same tests you have had before, but they also could have been for different things.
I had done them done at 10 weeks, It hink they took 5-6 samples for different things. The ones I can remember were full blood examination, thalassemia, syphellis, rubella immunity. there was also a midwstream test for UTI and I think something else.
The other one was for the first trimester screening test, which gets combined with the 12 week scan NT measurement & age factors to give a ratio of risk for DS.

If you didnt have them they may give you a form to have BT @ 16 weeks instead. Discuss it with your DR and ask what the test are for.
