Screening and Diagnosis of Prediabetes


Prediabetics will never know by their own about their high blood sugar. If they are suffering from the mentioned factors which indicates risk zone, they should periodically go for routine check up and should be cautious enough about the given signs and symptoms. Once they crossed the age of 45, they must routinely visit a doctor and ask for its diagnosis.

There are two types of blood tests to determine whether you are suffering from prediabetes or not, they are as follows:

  • Fasting blood glucose test : A fasting blood sugar level under 100 milligrams of glucose per deciliter of blood (mg/dl) is considered normal. If your blood sugar level is 100 to 125mg/dL, you have prediabetes - also called impaired fasting glucose (IFG). If you are suffering from prediabetes then the fasting blood sugar as well as post postprandial blood sugar will fluctuate easily.
  • Oral Glucose Tolerance Test (OGTT) : After fasting for at least eight hours, FBS (fasting blood sugar) is checked and then an oral dose of 8 ounce sugary syrup is administered. The blood glucose level is checked after an hour and if it reaches 144-199 mg/dl after two hours, you have impaired glucose tolerance.
