What is Fasting for Glucose Test?
A blood glucose test is used to measure the amount of glucose present in the sample collected from a patient who is suspected of being in their pre-diabetic stage. The test can also be prescribed by a doctor for a patient who is receiving treatment for diabetes in a bid to gauge whether the treatment is working or not.
When one consumes carbohydrate-rich food items, the body breaks down the carbohydrates to turn the same into energy. When carbohydrate is broken down, the resulting molecules are glucose. Excess or low blood glucose levels are problematic as abnormal blood glucose levels indicate that the person has a serious underlying medical condition.
A fasting plasma glucose test in Hyderabad at Vijaya Diagnostic Centre looks like this.
A sample of blood will be collected from a patient using a small needle from any of the veins present in the arms of the patient. After that, the sample will be tested using the hexokinase method.
When You Need Fasting for Glucose Test?
A fasting glucose test is done when a person wants to know whether they have type 1 diabetes, type 2 diabetes, or gestational diabetes. This test can also be used to gauge whether the treatment for the above-mentioned variants of diabetes is working or not. The level of sugar in the blood of humans is controlled by a hormone that is known as insulin. Insulin is created in the pancreas. A person will become diabetic if their pancreas malfunctions. In simple words, when the pancreas of a person doesn’t make insulin in the right amounts then the person becomes diabetic. With the help of this test, blood sugar levels can be managed. It is very important to ensure that the blood sugar levels are under control as excess sugar in a person’s blood can lead to kidney disease, blindness, and heart disease!
