Normal Blood Sugar Level for a Non-Diabetic Patient

Blood sugar is measured either at a laboratory or home. Blood sugar measurements are an important tool for maintaining normal blood sugar level ranges generally less than 100 mg/dL (milligrams per deciliter).

Home Blood Glucose Monitoring

Using a glucometer (blood sugar testing machine), an individual can take a sample to test blood sugar levels. Prior to meals, blood sugar levels range from 70 to 130 mg/dL. After meals the range should be less than 180 mg/dL.

Fasting Blood Glucose

Normal fasting blood glucose levels range from 70 to 99 mg/dL. When fasting, individuals are required not to consume food at least eight hours prior to testing.

Oral Glucose Tolerance Test (OGTT)

An oral glucose tolerance test (OGTT) is performed two hours after drinking a 75 gram glucose drink. The normal levels after an OGTT test is performed are 140 mg/dL or less.

Gestational Diabetes Screening

Gestational diabetes screening is performed during week 26 to 28 of pregnancy. After drinking a 50 gram glucose drink, a blood test is performed one hour after consumption with normal levels being less than 140 mg/dL.

Gestational Diabetes Diagnostic: OGTT

At fasting, normal level should be less than 95 mg/dL. After the fasting blood draw, a 100 gram glucose drink is consumed and blood is drawn four additional times. Ranges for one hour are less than 180 mg/dL, two hours is less than 155 mg/dL and under 140 mg/dL after three hours.
