The steps for Down syndrome screening are as follows:

Although Down syndrome screening is not complicated and the steps are very simple, there are still some things that need attention during the process. If pregnant women do not have a clear understanding of the relevant steps before doing Down syndrome screening, it is very likely that they will be asked by the doctor to go home and make sufficient preparations before going to the hospital for Down syndrome screening because they are not fully prepared for one step. So, what are the steps for going to the hospital for Down syndrome screening?

The process of Down syndrome screening is as follows

The most important point in Down syndrome screening is to be on an empty stomach, which is also the point most often overlooked by many pregnant women who are not very familiar with the Down syndrome screening steps. Since Down syndrome screening is mainly a blood test, it is necessary to extract blood from pregnant women and measure the concentrations of substances such as alpha-fetoprotein, human chorionic gonadotropin and free estriol in their blood cells. If the pregnant woman has eaten or drunk water within 12 hours before the Down syndrome screening, it will affect the concentrations of various substances in the pregnant woman's blood. Therefore, if pregnant women are not fasting before going to the hospital for Down syndrome screening, doctors will usually tell pregnant women to wait until they are fasting next time before going to the hospital for a physical examination.

In addition to fasting, pregnant women are advised to bring a medical certificate when going to the hospital for Down syndrome screening. If they don't have one, they should create one and tell the doctor their exact age and weeks of pregnancy in detail. After the blood test at the hospital, they should measure their weight, because Down syndrome screening also needs to be combined with the pregnant woman's age, weight and weeks of pregnancy to calculate the final result. After finishing these, you can go home and wait for the results of the Down syndrome screening. In this way, the process of going to the hospital for Down syndrome screening is completed.

The above article has already explained the steps for going to the hospital for Down syndrome screening. The probability of high risk in Down syndrome screening is not very high. Even if the Down syndrome screening finally gets a high-risk test result, after further confirmation by amniocentesis, most pregnant women are safe, so pregnant women do not need to worry too much.
