A glucose tolerance test during pregnancy is also known as an oral glucose tolerance test for pregnant women, which is mainly to see if the pregnant woman’s blood sugar is normal and if she has gestational diabetes. The cost of having a glucose tolerance test during pregnancy is not high, about 50-100 yuan, depending on the level of the hospital and the city where it is located. The time to have a glucose tolerance test is after 24 weeks of pregnancy, mainly to see if the pregnant woman has gestational diabetes. If gestational diabetes is not treated in time, it can be life-threatening for the fetus, so it is very necessary to have a glucose tolerance test. The cost of the glucose tolerance test is not expensive, usually around 60 yuan, and the test can be performed in any national public hospital. The higher the level of the hospital, the higher the cost may be, and it also has a certain relationship with the city where it is located. The consumption in big cities is higher, so the fees will be higher than those in small cities. Generally, the time to do the glucose tolerance test is before 8:30 am and requires fasting, so pregnant women cannot eat when they go for the test, and the whole process takes about 2-3 hours to complete. If a pregnant woman has gestational diabetes, she should control the absorption of sugar, not eat foods with high starch and sugar content, and check her blood sugar regularly.
