Blood (FBS)

A blood sugar test  (FBS) is usually performed to measure blood glucose levels after a certain period of fasting.

In healthy people, the hormone insulin helps to reduce blood sugar levels after fasting, but in diabetics the hormone does not function properly, so the glucose level is found to be higher. The test is used to diagnose diabetes or to test the effectiveness of diabetes medication in people who have already had diabetes.
Denis SlinkinThe best time for a blood glucose test in a fast is in the morning, according to Dr. Denis Slinkin, and the test is carried out after a person has been fasting for at least 8 hours. And before taking the test, it is important to tell the doctor what drugs you take regularly, including prescription and over-the-counter drugs. Your doctor may advise you to stop taking the medicine or to temporarily change your dosage before you take the test. A blood test (FBS) tube is needed for the glucose test, so the lab technician will draw the blood according to the instructions:
He will wrap an elastic band around your shoulder.

Clean the skin where the blood is coming from with an antiseptic, i.e. either on the inside of your elbow or on the back of your arm.

Insert a needle into a suitable vein.

Place the tube in the puncture site and collect the blood.

Remove the needle and elastic bandage as soon as the blood is collected and place the bandage at the puncture site.

The whole process will take about 1-2 minutes.
