What is the normal range for 1 hour glucose test during pregnancy?

Is it common to fail 1 hour glucose test?
Odds of passing. The truth about this test is that the one-hour test is pretty easy to “fail,” and many people do! They make the threshold low enough so that they catch anyone who could be having an issue, just in case. The levels on the three-hour test are much more reasonable and easier to meet.
How accurate is the one hour glucose test?

What is normal glucose level?
A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours indicates diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) indicates prediabetes.
