What else should I know?
The HbA1C results can be inconsistent. Moreover, it’s not an appropriate test for pregnant women and those who have another form of hemoglobin (variants). Lastly, results could be inaccurate if the person being tested has anemia.
Fasting Blood Sugar (FBS)
Many Filipinos are familiar with fasting blood sugar. It’s perhaps the most well-known diagnostic test for type 2 diabetes because it’s straightforward, highly available, and inexpensive. Also called the fasting plasma glucose test, it checks for the blood glucose level at the time of the screening.
What happens during the test?
The test is best done in the morning because it requires you to fast for at least 8 hours and not exceeding 12 hours. This means you cannot eat or drink anything (other than sips of water) 8 hours before FBS. In the clinic or hospital, a healthcare worker will draw blood from you and submit it to the laboratory for testing.
How do they diagnose type 2 diabetes using FBS?
When you receive the results of your FBS, you’ll see numbers:
- A blood sugar level of 99 mg/dl or lower is normal.
- If it’s 100 to 125 mg/dl, it could mean prediabetes.
- A result of 126 mg/dl or higher on two separate FBS means the patient has diabetes.
