What is the glucose tolerance test ?
Glucose tolerance test is a test that measures the body's response to sugar (glucose ) . It is also known as glucose tolerance test oral oral glucose tolerance test. Can be used glucose tolerance test for the early detection of diabetes type II . Also uses the test more common way of a modified glucose tolerance test for the diagnosis of gestational diabetes , a type of diabetes only be infection during pregnancy.

Why is performed glucose tolerance test
Glucose tolerance test determines how to address the imbalance in the body and treated with glucose after eating a meal . And through this test and the discovery of a defect in the metabolism of glucose , even before it becomes a level of fasting blood glucose is normal in many cases .

Preparations before the glucose tolerance test

    It is essential that the patient eat and drink as normal in the days preceding the glucose tolerance test .
    You must tell your doctor the state of health of the patient and if he was suffering from any disease or dealing with any medications , as these factors can affect the test results.
    Patient refrain from food and drink for eight hours prior to testing . Therefore, preferably a test early in the morning so that the patient is fasting the night before the test .

Steps glucose tolerance test
 Steps glucose tolerance test

Glucose tolerance test is in several steps .


Sample is taken from the blood by inserting a needle into a vein in the arm .

Sample is taken from the blood by inserting a needle into a vein in the arm .

Use this blood sample to measure the level of fasting blood sugar .

Diabetes Type II
In the case of testing for diabetes type II : After taking a blood sample from the patient to drink 237 milliliters of almost sweet glucose solution , which contains 75 grams of sugar .
Glucose solution

Two hours later another sample is taken from the blood to measure the level of glucose in the blood again.

Gestational Diabetes
Gestational Diabetes
It is recommended that test blood glucose after one hour for pregnant women that have a low risk of exposure to gestational diabetes for early detection of infection gestational diabetes . In the case of the emergence of the test result after hour calls for doubt in the incidence of gestational diabetes are checking your blood glucose after a longer period .


That is the test steps in detail :

    Be a pregnant woman fasting for 8 hours before the test .

    Is taking a sample of blood to check blood sugar fasting.

    Ms. drinking 237 milliliters of glucose solution that contains 100 grams of sugar .

    3 is taken other samples from the blood after the first hour , then two hours after the second , then the third sample after 3 hours of eating glucose solution to check the level of glucose in the blood in each blood sample .

Thus, the test has ended completely and lady can go home to practice normal daily activities .

Results glucose tolerance test

Results measured glucose tolerance test unit milligram per deciliter (mg / dl ) or mmol per liter ( mmol / l).

Diabetes Type II
As a result the level of blood glucose two hours after drinking the glucose solution :

The level of sugar in normal blood :
Less than 140 mg / dL ( 7.8 mmol / l).

The level of sugar in the blood non- natural :

    Blood sugar level between 140 mg / dl and 199 mg / dL ( 7.8 and 11 mmol / l ) : The pre- diabetes ( diabetes introductions ) .
    This indicates that the person is at risk of developing diabetes later. Also be at risk of heart disease , even if they did occur diabetes .

    Blood sugar level of 200 mg / dL ( 11.1 mmol / L ) or higher : Refers to diabetes .

In that case, the test may be repeated in another day or use another blood test to confirm the diagnosis .

There are various factors that can affect the accuracy of the glucose tolerance test , including illness , activity level , and some medicines . So may recommend repeating the test in some cases .

 


Gestational Diabetes
Are diagnosed with gestational diabetes incidence in the case of the emergence of two or more of the results of measuring the percentage of sugar in the blood samples of the four ( the fasting person , one hour after drinking the glucose solution , two hours after drinking the glucose solution , after 3 hours of drinking glucose solution ) is higher than normal.

The level of sugar in normal blood :

    Fasting : Less than 95 mg / dL ( 5.3 mmol / l).

    One hour after drinking the glucose solution : less than 180 mg / dL (10 mmol / l).

    Two hours after drinking the glucose solution : less than 155 mg / dL (8.6 mmol / l).

    Three hours after drinking the glucose solution : less than 140 mg / dL ( 7.8 mmol / l).

In that case, you should prevent complications to the mother and fetus during pregnancy by good control of blood glucose levels during the remainder of the pregnancy . By maintaining an insulin doses prescribed by your doctor and be bound by the special diet free of fat and foods and drinks that contain large amounts of sugar.
