In brief: No.
Gestational diabetes testing involves a screeing test with 50 grams of glucose in liquid, then checking the blood sugar level an hour later. If that level is too high, then a formal glucose tolerance test should be done (several hours long).
An A1c level of glycohemoglobin which is elevated would be suspicious for gestational diabetes, but it's not the preferred diagnostic test.

The main problem with using A1c in pregnancy is that it reflects 3 months of sugars. Due to changes in hormones throughout the pregnancy, sugars can change significantly over a few weeks. Doctors don't want to wait until blood sugars have been high for 3 months - they want to know what's going NOW and help you fix it now if needed.
