In diagnosing whether a person has prediabetes or diabetes mellitus, a doctor normally relies on the outcomes of some specific glucose tests.
Although the traditionally favored methods are Fasting Plasma Glucose (FPG) test and Oral Glucose Tolerance Test (OGTT), Many studies show that haemoglobin A1C or HbA1c test is a better test for prediabetes.
If in case you have pre-diabetes and you go for Fasting blood glucose test, it is not mandatory that FBG will likely be in prediabic range from 100 to 125mg/dl all the times. Sometimes you may get values even below than 100 where you'll not be labeled as prediabetic, and you'll remain as normal. but this isn't so. However if you're a prediabetic patient, and you go for HBA1c% test, everytime you'll get similar values of HbA1c over time.
So why is it that your FPG is already back to normal however HbA1c remains to be prediabetic? For FPG, the test measures the blood glucose or sugar levels after fasting for about 12hours. Outcomes could also be differ from lab to lab / day …show more content…
What's HbA1c Test: Haemoglobin (Hemoglobin) A1c test or HbA1c test is a blood test which reveals the average blood glucose levels over a period of about 8 to 12 weeks or 2 to three months, which is the lifetime of a average red blood cell.
Haemoglobin is the color pigment in the red blood cells that carries oxygen around the body. Glucose attaches to this pigment to make a "glycosylated haemoglobin" molecule called haemoglobin A1C or HbA1C. Due to this fact, the higher the haemoglobin A1C or HbA1c percentage, the higher the glucose in the blood.on general, a non-diabetic individual's HbA1c preferrred results should be lower than 5.5%. A level above 7% reveals diabetes and ranges between 5.5 to 6.9% are considered
