“Diagnosing DIABETES and Learning about PREDIABETES”
There are several ways to diagnose diabetes.

1. - RESULT OF HAEMIGLOBIN Hb A1C:
The A1C test measures your average blood glucose for the past 2 to 3 months. The advantages of being diagnosed this way are that you don't have to fast or drink anything.
*Diabetes is diagnosed at an A1C of greater than or equal to 6.5%
A1C Normal..: less than 5.7%
Prediabetes..: 5.7% to 6.4%
Diabetes…....: 6.5% or higher
2. - RESULT FASTING GLUCOSE:
Fasting Plasma Glucose (FPG)

This test is usually done first thing in the morning, before breakfast.
Diabetes is diagnosed at fasting blood glucose of greater than or equal to 126 mg/dl.
Fasting Plasma Glucose (FPG) Normal less than 100 mg/dl
Prediabetes……: 100 mg/dl to 125 mg/dl
Diabetes………..: 126 mg/dl or higher
3.- RESULT OF ALA GLUCOSE TOLERANCE CURVE:
Oral Glucose Tolerance Test (also called the OGTT)
