Blood glucose testing is an important part of diabetes screening, diagnosis and monitoring. However, different blood sugar tests provide different types of information.
The diabetes profile listed by ABTA Advanced Clinical Laboratory, Titakudi includes:
- Fasting Blood Sugar (FBS)
- Postprandial Blood Sugar (PPBS)
- HbA1c
- Fasting Insulin
Understanding the purpose of these tests can help patients better understand why their healthcare professional may request more than one blood glucose investigation.
What Is a Diabetes Profile?
A diabetes profile is a combination of laboratory investigations used to evaluate blood glucose and related markers.
Rather than depending on a single measurement, healthcare professionals may use different tests depending on whether they are screening for diabetes, evaluating symptoms or monitoring an existing diagnosis.
What Is Fasting Blood Sugar?
Fasting Blood Sugar (FBS) measures blood glucose after a period of fasting.
It provides a measurement of blood glucose at a specific point in time.
CDC information lists fasting blood sugar as one of the tests used for diabetes and prediabetes evaluation.
Because fasting is important for this test, patients should follow the preparation instructions provided by the healthcare professional or laboratory.
What Is PPBS?
PPBS stands for Postprandial Blood Sugar.
Unlike a fasting measurement, a postprandial blood sugar test evaluates blood glucose after eating.
This provides a different view of glucose levels compared with fasting blood sugar.
The timing of the sample in relation to the meal is important, so patients should follow the specific instructions given when the test is ordered.
What Is HbA1c?
HbA1c, also called A1C, is different from FBS and PPBS.
Instead of measuring blood glucose at one particular moment, A1C provides an estimate of average blood glucose over approximately the previous two to three months.
This makes HbA1c useful for both diabetes screening/diagnosis and monitoring in appropriate clinical situations.
Does HbA1c Require Fasting?
Generally, HbA1c does not require fasting.
However, if your doctor has ordered other tests at the same appointment, those tests may require fasting.
Therefore, always check the complete test package before eating or drinking.
Understanding Common HbA1c Ranges
For diabetes and prediabetes assessment, commonly used A1C ranges are:
- Below 5.7%: Normal
- 5.7%–6.4%: Prediabetes
- 6.5% or above: Diabetes range
These values are used as diagnostic criteria in appropriate clinical settings, but diagnosis should be made by a healthcare professional and may require confirmation or additional testing.
Why Can More Than One Diabetes Test Be Ordered?
FBS, PPBS and HbA1c answer different questions.
FBS
Provides information about blood glucose after fasting.
PPBS
Provides information about blood glucose after a meal.
HbA1c
Provides an indication of average blood glucose over the previous two to three months.
Because these tests measure different aspects of glucose control, a healthcare professional may choose one or several depending on the patient’s situation.
What About Fasting Insulin?
ABTA’s listed diabetic profile also includes fasting insulin.
Insulin is a hormone involved in regulating blood glucose. A fasting insulin test may be requested in specific clinical situations and should be interpreted along with other findings.

Why Regular Testing Can Matter
Diabetes management is not based only on how a person feels on a particular day.
Blood glucose changes over time, which is why laboratory testing can provide objective information for screening and monitoring.
For people already diagnosed with diabetes, A1C is commonly used to monitor average blood glucose and assess how well the condition is being managed.
Final Thoughts
FBS, PPBS and HbA1c are not identical tests.
FBS evaluates fasting glucose, PPBS evaluates glucose after eating, and HbA1c provides information about average blood glucose over the preceding two to three months.
ABTA Advanced Clinical Laboratory lists all three among its diabetic profile investigations, along with fasting insulin.
If your doctor has recommended diabetes testing, follow the preparation instructions carefully and discuss your results with your healthcare professional.
