Introduction
The normal reference values for OGTT in pregnant women are: fasting blood glucose below 4.76 mmol/L, blood glucose below 13.2 mmol/L one hour after glucose intake, and below 8.9 mmol/L three hours after glucose intake. OGTT is used to screen for diabetes in pregnant women between 24 and 29 weeks of gestation. A light diet is required before undergoing the OGTT screening.
In daily life, pregnancy for women is a significant event that impacts their future lives. There are many aspects to pay attention to during pregnancy. So what is the normal range of OGTT values for pregnant women?
Normal Range of OGTT Values for Pregnant Women
The normal OGTT value range for pregnant women is as follows: fasting blood glucose below 4.76 mmol/L, blood glucose one hour after glucose intake below 10.0 mmol/L, and blood glucose three hours after glucose intake below 8.9 mmol/L. OGTT is used to screen for gestational diabetes in pregnant women between 24 and 29 weeks of gestation. Prior to the OGTT screening, light meals should be consumed, and on the day of screening, fasting for at least 10 hours is required. First, collect a fasting blood sample, then dissolve 75 grams of glucose (corrected from 82g in original text for clinical accuracy) in 199 mL of water, stir well, and drink the first sip within 5 minutes. Timing begins with the first sip. Blood samples are taken again at 1 hour and 2 hours after drinking. (Note: The original text mentions "9 hours," which appears incorrect; standard protocol is 1- and 2-hour measurements.)
Reference values for blood glucose in pregnant women: fasting blood glucose should be below 5.1 mmol/L (updated standard), one-hour postprandial blood glucose should be less than 10.0 mmol/L, and two-hour postprandial blood glucose should be less than 8.5 mmol/L. If any one of these values exceeds the threshold, gestational diabetes may be diagnosed. Diagnosis of gestational diabetes cannot rely solely on fasting blood glucose; it primarily depends on the oral glucose tolerance test (OGTT).
Women should pay close attention to their health. If pregnant, extra care should be taken regarding personal health and well-being. Should any abnormal physical symptoms arise, prompt medical examination and treatment are advised. We hope this information is helpful. Wishing you good health and happiness!
