Glucose Tolerance Test, 3-hour
$101
Glucose is a small sugar molecule that is used in all the cells in the body as the main energy source in metabolism and cellular functions. The brain and the nervous system can only use glucose and no other sources or molecules for energy, therefore, there needs to be a steady amount of glucose available in the blood for the brain. Testing the blood for glucose is primarily used for the diagnosis of glucose intolerance and diabetes and to monitor the blood glucose for people on treatment of diabetes. There are many different ways to test glucose levels. This test measure the glucose after fasting and then having a sample of glucose drink to see how the body’s response is to glucose 3 hours later.
This test is performed in following conditions such as:
• Sweating
• Palpitations
• Hunger
• Confusion
• Blurred vision
• Dizziness
• Fainting
• In serious cases, seizures and loss of consciousness
