what sugar glucose numbers is dangerous for daily fasting testing

Hello Anon

Thank you for writing!

Usually a person will fast for eight hours, maybe six hours, before blood is drawn.

A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes.

Values may be affect on what the person ate the evening before.

Best,
Susan
