Glucose Tolerance Test


Glucose Tolerance Test

A glucose tolerance test is used during pregnancy to check for gestational diabetes.

Gestational diabetes is a high blood sugar status that develops during pregnancy in women that did not have this issue before. The Oral Glucose Tolerance Test (OGTT) determines whether gestational diabetes may be present so that it can be treated if necessary. The rising of your blood sugar level will be measured after drinking a concentrated glucose drink.


On the day of your test you come to the laboratory after fasting for at least 10 hours. This means that you have not eaten anything, not even gum, have not smoked and did not drink anything but water, tea or coffe, without sugar or milk.

You can bring some breakfast for after the test is finished. Usually something savoury is prefered.

The test

The test will start with the drawing of some blood, from your finger. You will then be given the concentrated glucose drink which you should finish fully within 5 minutes. This drink contains 75 grams of glucose and therefore tastes very sweet. Two hours after drinking the glucose your blood will be taken again. After this you can eat your breakfast.

During the two hour wait you are again not supposed to eat or drink anything. It is best to keep quiet and pass the time sitting. Because of this long wait it is advised to bring something, like some reading material, to keep you occupied.

Beste cliënt,

Op dit moment mogen wij tot onze spijt geen echo's op eigen verzoek (pret-echo's) meer uitvoeren. 

In verband met het niet kunnen handhaven van de 1,5 meter tijdens het maken van een echo willen wij jullie verzoeken om een mondkapje mee te nemen naar de echo.

Daarnaast mag er naast de zwangere maximaal 1 persoon meekomen naar de echo. Neem dus geen kinderen mee! Wij vragen jullie om niet te vroeg te komen zodat er niet teveel mensen tegelijk in de wachtkamer zitten.

Bij klachten als hoesten, niezen, koorts en neusverkoudheid vragen wij je om je afspraak telefonisch te verzetten. Een partner met klachten mag niet mee naar binnen.

Alvast bedankt voor jullie medewerking.
met vriendelijke groet,
medewerkers van Echo Amsterdam

Dear cliënt,

NEW: We regret to inform you we are not allowed tot perform any scans upon request.

Due to the inability to maintain the 1.5 meters range while making an ultrasound, we want to ask you to bring a  facemask to the ultrasound.

You are allowed to bring maximum one extra person besides yourself to your scan. You are not allowed to bring your children.

Please don't arrive too early to prevent too many people in the waiting room at the same time.
When you or your partner are coughing, sneezing or having a fever, we ask you to reschedule your appointment by telephone.

Thanks for your coöperation,
best regards,
the team of Echo Amsterdam
