Blood Check

HbA1c (Glycated hemoglobin test)

This blood test indicates your average blood sugar level for the past two to three months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells. The higher your blood sugar levels, the more hemoglobin you’ll have with sugar attached. An A1C level of 6.5 percent or higher on two separate tests indicates that you have diabetes. An A1C between 5.7 and 6.4 percent indicates prediabetes. Below 5.7 is considered normal.

Advantages of doing this test:

  • Chronic hyperglycaemia is captured with HbA1c test.
  • No acute disturbances (e.g. stress, diet, exercise and smoking) effect HbA1c values, hence no fasting required.

Fasting plasma glucose (FPG)

A Fasting plasma glucose test helps in the diagnosis of Diabetes. This is a simple blood test taken after 8-10 hours of fasting. For undergoing the test, patients are advised not to eat or drink anything except water for 8 to 10 hours before the test is performed. Any patient who develops diabetes symptoms including polyuria, polydipsia and weight loss should be tested immediately.

The American Diabetes Association (ADA) states that:

Result FPG Values
Normal < 100 mg/dL
Prediabetes 100 mg/dL to 125 mg/dL
Diabetes 126 mg/dL or higher

 

Advantages of doing an FPG test:

  • Widely available
  • Inexpensive

Post-prandial Plasma Glucose (PPG):

A Postprandial Plasma Glucose Test is a blood test that measures blood glucose levels following a meal containing a set amount of carbohydrate.

Postprandial Plasma Glucose Tests show how tolerant the body is to glucose.

The American Diabetes Association (ADA) states that:

Result PPG Values
Normal < 140 mg/dL
Prediabetes 140 mg/dL to 199 mg/dL
Diabetes 200 mg/dL or higher

 

Advantages of doing a PPG test:

  • Widely available
  • Inexpensive
