What is the difference between sugar sieving and sugar sieve?

"Tang sieve" and "sugar sieve" may sound like the same word, but the content is very different. These two words represent two kinds of examinations during pregnancy, and it is often found that many expectant mothers confuse the two, so today we might as well talk about the difference between the two. First of all, the meaning is different.

"Tang screen" is the abbreviation of Down screening, and "sugar screen" is the screening for gestational diabetes.

Secondly, the content of the examination is different. Tang screening is mainly for the screening of Down syndrome, that is, to check whether the baby will be born with stupid Down's syndrome, mainly to check alpha-fetoprotein, human villous gonadotropin, and free estriol. The sugar screening is used to screen for gestational diabetes, mainly to check the blood sugar status of the expectant mother.

Moreover, the time of the examination is different. Tang screening is generally performed at 15-20 weeks of pregnancy, and sugar screening is usually performed at 24 weeks.

In addition, the precautions are different. Although all blood is drawn, Tang Sieve does not need to draw blood directly on an empty stomach, while Sugar Sieve needs to stop eating and drinking 12 hours in advance, and then take blood 1 hour after oral glucose water.

Then there is the fact that the follow-up procedures are also different. If the sieves show high risk, the doctor will recommend amniocentesis for further analysis, and if the sieves are high-risk, the doctor will recommend continuing the glucose tolerance test.

Difference Between Sugar Sieve and Sugar Tolerance:

1. Difference in categories:

Sugar screening is the abbreviation of gestational diabetes screening, sugar screening is a way to check blood sugar and blood, blood sugar is too high to lower the blood sugar.

Glucose tolerance is done when further testing is required when the sugar sieve fails. In other words, a sugar sieve test is performed before a glucose tolerance test can be performed.

2. The difference between the inspection method and the normal value:

12 hours before sugar screening, dissolve 50 grams of glucose powder in 200ml of water, drink it within 5 minutes, start the timing of the first sip, and draw blood to check blood sugar 1 hour later, the blood glucose value is abnormal for sugar screening, and further glucose tolerance test is required.

12 hours before the glucose tolerance test, first fasting blood draw to check blood sugar, then add 150ml of 50% glucose injection to 100ml of water, or dissolve 75 grams of glucose powder in 300ml of water, drink it within 5 minutes, start the timing of the first sip, and draw blood to check blood sugar after 1 hour, 2 hours, and 3 hours.

The standard of normal value is: fasting, 1 hour per hour, 2 or more of which reach or exceed the normal value, the diagnosis of gestational diabetes can be made, and only 1 item above the normal value is the diagnosis of impaired glucose tolerance.

1. The functions are different.

Sugar screening is the abbreviation of gestational diabetes screening, and if sugar screening is high-risk, doctors will recommend continuing to do glucose tolerance testing to confirm whether there is gestational diabetes. Severe sugar screening can threaten the life safety of mothers and babies.

Down Syndrome Screening is the abbreviation of Prenatal Screening Test for Down Syndrome, which is a special examination method. The purpose is to test the blood of pregnant women, detect the concentration of alpha-fetal protein, chorionic gonadotropin and free estriol in maternal serum, and judge the risk factor of fetal congenital stupidity and neural tube defects in combination with the age, weight, gestational age and other aspects of pregnant women.

2. The role is different.

The ultrasound and serological indicators of Down's screening have an important position in the prenatal screening indicators, but also have their own clinical characteristics detection time and test results, and the combination of these parameters for prenatal screening not only improves the sensitivity and specificity, but also makes up for the shortcomings of a single test.

Diabetes mellitus, which is detected or first developed after pregnancy, is called gestational diabetes, and its incidence tends to increase, accounting for about 10% of all pregnant women. This is due to the fact that during pregnancy, various factors can cause abnormal glucose metabolism, but many people do not have corresponding symptoms, and even fasting blood sugar is normal, so it does not attract corresponding attention.

3. The inspection method is different.

Down's screening is to calculate the risk factor of giving birth to a fetus with birth defects by sampling the serum of pregnant women, measuring the concentrations of alpha-fetal protein, chorionic gonadotropin and free estriol in maternal serum, and combining the expected date of delivery, age, weight and gestational age at the time of blood collection.

The examination of sugar screening can be random, that is, there is no restriction on diet, only asking not to drink sweet drinks in the early morning and not to eat too sweet foods. However, the glucose tolerance test requires fasting for 8 hours and a fasting blood glucose test before 10 a.m., which is equivalent to no so-called fasting time for the previous night, just an examination of the fasting on the same day.

Sugar sieve is an oral administration of 50g of glucose mixed with 250 ml of water within five minutes of drinking the blood sugar after one hour of measurement, the normal value is less than; Glucose tolerance is done again on the basis of the abnormality of Tang Sieve, that is, to take blood to test blood sugar on an empty stomach, drink 75g of grape stool sugar mixed with 250ml of water, wait for one hour and two hours to draw blood for blood sugar test, fasting is less than one, one hour is less than 10, and less than two hours is normal.

Glucose tolerance. What is human glucose tolerance? In layman's terms, it is the body's ability to tolerate glucose. Hospitals usually test glucose tolerance in patients with suspected diabetes if the glucose tolerance test is between 2 hours after taking the glucose.

milliliters, indicating that the body's glucose tolerance ability is reduced, that is, the body's absorption and utilization of sugar is worse than that of ordinary people.

Glucose tolerance is impaired and there is no significant discomfort, but it should not be taken lightly.

Sugar sieve. "Sugar screening" is the abbreviation of gestational diabetes screening, and the doctor will recommend continuing to do glucose tolerance testing to confirm whether there is gestational diabetes.

That's it.

Sugar sieve is an oral administration of 50g of glucose mixed with 250 ml of water within five minutes of drinking the blood sugar after one hour of measurement, the normal value is less than; Glucose tolerance is done again on the basis of the abnormality of Tang Sieve, that is, to take blood to test blood sugar on an empty stomach, drink 75g of grape stool sugar mixed with 250ml of water, wait for one hour and two hours to draw blood for blood sugar test, fasting is less than one, one hour is less than 10, and less than two hours is normal.

The beginning of a new phase of our lives is marriage, which means that we will say goodbye to our single life and begin the process of struggle between two people. For a newly formed family, the happiest thing for a newlywed couple is to get pregnant. The arrival of a new baby fills the whole family with laughter, but now it is different from the past, and now the pregnancy period is very meticulous, and you have to be very careful in eating and sleeping, and at the same time, you still need to do a lot of tests.

Next, let's analyze the difference between Tang sieve and sugar sieve**?

1. Although the pronunciation of the two is the same, the content of the examination is different, and the Tang screen is mainly a prenatal screening test for Down syndrome, to check whether the baby is a congenital stupid type of Down child, mainly to check free estriol, alpha-fetoprotein and other hormones. Sugar screening is a screening for gestational diabetes, which mainly checks the blood sugar status of pregnant mothers, so as to determine whether they have gestational diabetes. <>

2. The time of examination is different, Tang screening is generally done at 15-20 weeks of pregnancy, and sugar screening is generally done at 24 weeks. At the same time, the doctor should understand the height, weight, and gestational age of the pregnant woman to judge the best time to do the Tang screening, and each hospital has different standards, so we should follow the doctor's advice. When doing sugar screening, the main thing is to understand the metabolism of glucose in the body of pregnant women, so they should not eat after 10 o'clock in the evening before the examination, and drink as little water as possible to avoid affecting the examination.

3. Under normal circumstances, most pregnant mothers have normal examinations, and don't be afraid of abnormal situations. If the Tang screening test is outside the normal range, the doctor will generally recommend the pregnant woman to do non-invasive DNA, because the detection rate of Tang screening is only about 60%, and the accuracy of the results is not very high, while the accuracy rate of non-invasive DNA is as high as 99%, so doing non-invasive DNA can make the results more convincing; If the sugar screening result is high, the doctor will generally advise the pregnant woman to control her diet, pay more attention to rest, and continue to do the sugar screening test after a week. <>

Both are examinations that pregnant mothers need to do during pregnancy, which can determine whether the baby is developing normally in the body, so pregnant mothers must go to the hospital regularly during pregnancy!

There are three differences between Tang screening and sugar screening, the first is that the meaning of the two examinations is different, "Tang screening" is the abbreviation of Down screening, while "sugar screening" is the abbreviation of gestational diabetes screening for variable diabetes. The second is that the content of the examination is different, Tang screening is a screening for Down syndrome, which is to check whether the baby will be a congenital stupid Down's child, and the examination indicators are mainly alpha-fetoprotein, human chorionic gonadotropin, and free estriol; Sugar screening is to check for gestational diabetes, mainly to check the blood sugar status of expectant mothers. The third is that the purpose of the examination is different, the sugar screening is to check whether the blood sugar is high and whether there is gestational diabetes, while the Down screening is to look at the intellectual development of the fetus.

Tang screening is to check the baby, check whether the baby is normal, whether there is Down syndrome, sugar screening can check pregnant women, to see if the pregnant woman has gestational diabetes, this is the difference between the two examinations.

The difference between Down's screening and sugar screening is that although both are items for pregnant women, the time and purpose of the examination are different.

Down's screening is to take the blood of pregnant women, measure the concentration of alpha-fetoprotein, HCG and free estriol in the serum of pregnant women, and determine the risk factors of fetal congenital stupidity and neural tube defects based on the age, weight and gestational age of the pregnant woman. This test is generally performed at 15 to 20+6 weeks of pregnant women and can be done without fasting. The vast majority of fetuses are normal during Down's screening for high risk, and only a few fetuses are abnormal, and amniocentesis is required to further rule out the possibility of fetal congenital stupidity.

Sugar screening is the abbreviation of gestational diabetes screening, to determine the existence of gestational diabetes, severe gestational diabetes can threaten the life safety of mothers and babies. The general examination time is 24-28 weeks of pregnancy, and fasting examination is required. If the sugar screen is abnormal, the doctor will instruct diet and exercise, monitor blood sugar, and take medications if necessary**.

Glucose toleranceWhat is human glucose tolerance? In layman's terms, it is the body's ability to tolerate glucose. If the glucose tolerance test is between milli mole within 2 hours after taking the glucose tolerance test, it indicates that the body's glucose tolerance ability is reduced, that is, the body's absorption and utilization of sugar is worse than that of normal people.

Glucose tolerance is impaired and there is no significant discomfort, but it should not be taken lightly.

Sugar screening is the abbreviation of gestational diabetes screening, and high-risk sugar screening doctors generally recommend continuing to do glucose tolerance testing to confirm whether there is gestational diabetes.

That's it.

Sugar sieve is a coarse sieve, which is the abbreviation of gestational diabetes screening, sugar sieve is a method of checking blood sugar and blood, blood sugar is too high to lower the blood sugar. Glucose tolerance is a glucose tolerance test (OGTT), which is a test done again in the event of an abnormality in the sugar sieve.
