Diabetes is so prevalent around the world that it can be called an epidemic. Recently, India has experienced a surge in cases of diabetes and prediabetes. Obesity, unhealthy diet and lifestyle habits, and genetics are some of its risk factors. Remember, diabetes symptoms can occur suddenly without any warning. Today, this disease is no longer limited to those who are middle-aged or older. With the busy lifestyle of the 21st century, the young generation is at a higher risk of diabetes.

To keep your blood sugar in check, it’s better that you get yourself tested regularly. A glucose test indicates the level of sugar and glucose in your blood. An abnormal level of blood sugar is associated with type-1 diabetes, type-2 diabetes, or prediabetes. If you already have diabetes, you can track and maintain normal blood sugar levels with this test.

You can take a sugar test using a portable blood glucose meter at home or a sugar test machine at a doctor’s office. Read on to know more about the important things about sugar test, its results, and possible side effects.

Why take a blood sugar test? 

A blood sugar test reveals the amount of sugar in your blood. Doctors use a glucose test to diagnose different types of diabetes. If you have any of them, you need to monitor your sugar levels constantly. This helps doctors know the effectiveness of the treatment.

You can use glucose tests to know the following.

  • Status of your blood sugar levels
  • Effectiveness of your current treatment plan
  • Efficacy of your diet and lifestyle
  • Your overall health if you are not diabetic

Your body converts carbs from foods into glucose. Glucose is the primary source of energy for the body. But, high or low levels of blood glucose can prove detrimental to your health.

  • High blood sugar or hyperglycemia can cause ketoacidosis, a fatal condition for type 1 diabetes patients. In this diabetic disorder, the body relies only on fat for energy. Hyperglycemia can cause further damage to the eyes, kidneys, and heart.
  • Low blood sugar or hypoglycemia, if left untreated, can cause coma or seizures.

Uncontrolled blood sugar can be life-threatening. So, you must monitor and manage your blood sugar levels.

What are the types of glucose tests?

There are different types of glucose tests. Depending on the purpose, doctors will recommend the right one to you.

  • Glycated hemoglobin (A1C) test: Thistest shows the amount of sugar attached to your hemoglobin. It is measured in percentage, and you do not have to fast for this test. A1C test is done to know your average sugar level for the past 2 to 3 months. The higher the sugar level, the higher the percentage of sugar attached to hemoglobin. An A1C level ranging from 5.7% and 6.4% indicates prediabetes. A1C level above 6.5% means you have diabetes. Anything below 5.7% is healthy.
  • Fasting blood sugar test: Here, you have to fast overnight before the test. Normal fasting blood sugar level is below 100 mg/dL. Anything between 100 mg/dL and 125 mg/dL is prediabetes. If your fasting blood sugar is 125 mg/dL or more, it means you have diabetes.
  • Random blood sugar test: This test can be done any time to check your immediate blood sugar. A sugar level of 200 mg/dL or more points to diabetes.
  • Oral glucose tolerance test: Multiple blood tests are conducted in this case. The first sample is collected after you fast overnight. Then, you have to drink a sugary liquid, after which your sugar level is measured periodically.

Read the table below to know what the results mean.

Results Range (mg/dL) 
Diabetes >200 
Prediabetes 140-199 
Normal <140 

How to decipher a sugar test result?

Normal blood sugar range varies as per the time of the test and your personal medical history. So, only your doctor can tell you if you are healthy or at risk. 

The table below shows the general sugar level range for people with and without diabetes.

Time People with diabetes (mg/dL) People without diabetes (mg/dL) 
Normal fasting blood sugar 80-130 <100 
Before meals 70-130 mg <110 
Normal blood sugar after eating (after 2 hours) <180 <140 
At bedtime <120 <120 

What are the possible side effects of taking a glucose test?

There are no severe or unhealthy side effects of a glucose test. You may just feel a little soreness at the site from where blood is drawn. However, it wears off within a day.

Diabetes is a slow killer with no cure, exposing you to numerous health problems. Your doctor will prescribe a treatment plan to manage or prevent diabetes, depending on your sugar test results.
