For the treatment of some diseases, it is important to choose the right time. Perhaps the earlier most diseases are detected, the better. This is because early detection can lead to better treatment. However, some diseases do require treatment after reaching a certain stage of development. This comes down to the vastness and profundity of medicine. Below, the editor will take you to see how to check the results of Down syndrome screening?
How to check the screening results of Down syndrome
When is the best time to do Down syndrome screening? 15-20 weeks of pregnancy is the optimal period for Down syndrome screening. The doctor suggests that the Down syndrome screening should be done for 15-20 weeks, but the specific time for Down syndrome screening varies depending on the hospital's situation. Please refer to the hospital's notification for the specific time. At this stage, the possibility of congenital ignorance can be predicted through examination. The main purpose of Down syndrome screening is to avoid the risk of congenital idiocy in fetuses to a certain extent.
How to do Down syndrome screening
Extract pregnant women's serum and detect pregnancy associated plasma protein A (PAPP-A), free hCGB subunits (early two items), alpha fetoprotein (AFP), chorionic gonadotropin (HCG), and free estriol (uE3) (mid three items) in maternal serum. Combined with the pregnant woman's expected delivery period, weight, age, and gestational age at the time of blood collection, calculate the risk factor for Down syndrome, which can detect 80% of Down syndrome infants. In the pre delivery screening of multiple indicators in maternal blood, radioimmunoassay, enzyme-linked immunosorbent assay, time-resolved immunofluorescence, and chemiluminescence methods are generally used. Due to the significant variation in the results of radioimmunoassay and enzyme-linked immunosorbent assay, time-resolved immunofluorescence and chemiluminescence methods are generally used. The country recommends time-resolved immunofluorescence method.
Do I need to go on an empty stomach for Down syndrome screening
Unlike general physical examinations involving liver function, Down syndrome screening does not require fasting. Recently, it was found that some sisters did not know whether they needed an empty stomach, mainly because the short name of Down's screening was "Tang Screen", which was very similar to the other word "Sugar Screen", and sounded exactly the same. However, unlike Down's screening, sugar screening is used to screen diabetes in pregnancy, which is generally done in 24 weeks and requires 12 hours of fasting. So, if you have doubts or cannot distinguish clearly, you may ask the doctor what kind of laboratory test report they have given you.
The above is the information compiled by the editor on how to check the results of Down syndrome screening. I believe it will be helpful to everyone. Everyone must understand that some diseases may not be very obvious when they appear, and it is necessary for everyone to discover them. It is better to detect and treat ordinary diseases early, and not delay. The editor wishes everyone no trouble from illness.
