I had a test to test a whole bunch of things at 10 weeks - haemoglobin, my blood type, sugar, any diseases, rubella immunity and all those things were done with that trst.

Then, I had another blood test for testing glucose and haemoglobin at 28 weeks. This was the glucose challenge test. My hospital does it for everyone, but i know that not all hospitals/obs do it as some of the ladies in my bellybuddies group didnt have it.

IF either of my blood tests were to show probs or potential issues, then I would have needed more, but the results were ok, so i havent needed more.
