What to do if i do not want to do a gestational diabetes test so can i just refuse it?

Ignorance is bliss?: Hi. I don't understand your attitude. If you know poor glucose control is bad for the baby, your reluctance (or refusal) is hard to understand. Ignoring reality doesn't make it go away. Just some thoughts. Generally, you can refuse ANYTHING a doctor recommends, but be aware you may harm the fetus. Go ahead and get an abortion if you don't want the pregnancy. Otherwise, try to be healthy.

Why jeopardize baby?: You could refuse it, but why? Having gestational diabetes could cause significant harm to you and/or your child. Simple dietary changes and/or meds could prevent that damage. There are other blood tests that can be done to assess for gestational diabetes, if you're reluctant to do the oral glucose challenge test. Ask your OB doc to refer you to an endocrine (or diabetes) clinic.
