I think LeonieD has a very valid point regarding testing for GD. Peeing on a stick is not an effective diagnostic tool. It is an old practice that we haven't got rid of because 'it's just the way we do things'. This includes the protein because in itself means nothing at all.
And the ranges for the GTT test vary with different labs, as do the approaches for when to begin treatment. I have had many many women (I work with a 'high risk' group) who have come back with a positive GTT, gone through the counselling, finger-pricking (always seeming to be normal), scare-mongering, induction/section, and had perfectly normal babies.
We don't routinely do bs on healthy normal babies - that too would be unethical - so our ranges for hypoglyclemia in the neonate are potentially skewiff too.
I agree that GD is over-diagnosed, with a clear lack of substantiated research. This is not to say that I don't recognise that in some women it is a very serious potential threat to their baby.
I'm also a little disappointed in the lack of respect for LeoniD's opinion . Everyone's opinion is as valid as anyone elses' and we all deserve respect. She's not telling anyone else what they should or shouldn't be doing, just voicing her ideas like the rest of us.
