What is blood glucose? The food that we consume is broken down by metabolic processes in our body and glucose is released into the blood. Our body utilizes this glucose (sugar) as a source of energy.
What Is Blood Glucose?
The food that we consume is broken down by metabolic processes in our body and glucose is released into the blood. Our body utilizes this glucose (sugar) as a source of energy.
How Is Glucose Formed in Body?
The diet that we consume contains very less glucose, but it contains complex carbohydrates that are broken down into glucose by metabolism.
In fasting condition, glucose is derived by the process of gluconeogenesis (process of production of glucose from glycerol, pyruvate, lactate, etc.) and glycogenolysis (process of breakdown of glycogen to glucose).
What Is Hyperglycemia and Hypoglycemia?
Presence of glucose in the blood acts as a signal for pancreas to secrete a hormone called insulin. The function of insulin is to signal cells of the body such as muscle cells and fat cells for uptake of glucose for obtaining energy and for storage.
Pancreas also secretes another hormone, which is, Glucagon. Glucagon has antagonistic action to Insulin hormone as Glucagon increases the level of blood glucose.
Elevated blood glucose levels above the threshold lead to Hyperglycemia condition and decline in blood glucose levels beyond a certain level leads to Hypoglycemia condition.
What Can Lead To Increase/ Decrease in Blood Glucose?
Following conditions can lead to an increase in blood glucose levels:
- Pancreas is not producing enough Insulin Hormone
- Pancreas producing excess Glucagon hormone
- Your body is not able to utilize insulin – insulin resistance
- Consumption of too much food having high carbohydrate content
- Sedentary lifestyle
- Side effects of medications such as steroids
- Hormonal imbalance
- Obesity
- Menstruation
Following conditions can lead to a decrease in blood glucose levels:
- Excessive insulin in the body
- Adrenal insufficiency
- Excessive alcohol consumption
- Insulinoma
What Are Blood Glucose Tests?
Blood Sugar Test/Blood Glucose Test –
Blood sugar test are performed to check the level of sugar (glucose) present in the blood at that the time of sample collection. Blood sugar levels keep fluctuating throughout the day and for diabetic people, the fluctuation takes place more often. Blood sugar test gives an idea about the instantaneous value of blood sugar level persistent in the body at the time of sample collection.
FBS –
FBS stands for Fasting Blood Sugar. After 8-10 hours of fasting at night, blood sample is taken in the morning before breakfast. Since, the sample is taken before consuming anything in the morning, the fasting blood sugar level is supposed to be the lowest.
PP –
PP stands for Postprandial. Blood sample is collected after consumption of a meal. It helps in assessing the quantity of glucose present in blood after eating. It is done after 2 hours of having meal.
Random –
Random Blood sample is collected at any time during the day, to check for instantaneous value of blood glucose level. Fasting or eating is not a requirement for this test.
What Is the Procedure for Blood Sugar Test?
Blood sugar testing can be done using 2 types of samples:
- Capillary blood sample collected from finger tip using a prick
- Venous blood sample collected from a vein in arm using a needle
After blood sample collection, blood sugar level is tested in the lab.
What Is the Price of Blood Glucose Test?
The price of blood sugar test varies from lab to lab, depending upon the type of blood glucose test, number of repetitions of test required and the location of lab.

How are blood glucose tests different from HbA1C?
Blood glucose test estimates the level of glucose present in the blood at the time of sample collection whereas HbA1c test estimates the percentage of glucose that is bound to RBCs in blood.
How to prepare for blood glucose tests?
Diet –
For Fasting Blood Sugar, fasting is required for 8-10 hours prior to giving blood sample.
For postprandial blood sugar, blood sample should be taken 2 hours after the meal.
For random blood sugar, fasting or meal is not a requirement.
Medical history – let your doctor know about your medical history for making an informed diagnosis
Medication – if you are taking medicines and insulin for diabetes, ask your doctor before getting blood sugar test done.
Are there any risks involved in getting blood sugar tests?
No, there are no risks involved in getting blood sugar tests done. Individuals may feel a little discomfort when blood sample is being collected. Dizziness and weakness is rarely seen in blood sample collection. Blood sugar test is a non-invasive procedure and hence it is safe.
