Introduction
The Down syndrome screening mainly assesses the risk of fetal abnormalities by measuring the levels of maternal serum alpha-fetoprotein, human chorionic gonadotropin, and other related hormones in the pregnant woman's blood, combined with gestational age, maternal age, and other factors. The test results are not affected by the time of day. Accurate results can be obtained when the test is performed in the afternoon, and the procedure is the same as in the morning; therefore, there is no need to worry about time interfering with the test.
Generally, Down syndrome screening can be performed in the afternoon. The detailed explanation is as follows:
Down syndrome screening primarily assesses the risk of fetal abnormalities by measuring levels of maternal serum alpha-fetoprotein, human chorionic gonadotropin, and other related hormones, combined with gestational age, maternal age, and other factors. The test results are not affected by the time of day, and accurate results can be obtained in the afternoon with the same procedures as in the morning, so there is no need to worry about time interfering with the test.
Some medical institutions may have different arrangements for specimen transportation or limited physician availability in the afternoon, which might delay the release of the report. However, this does not mean the test itself has specific time requirements. Understanding the specific arrangements of the institution in advance can help avoid such situations.
Pregnant women should maintain a positive and optimistic mindset, follow a balanced diet, engage in moderate exercise, undergo regular prenatal checkups, and follow professional medical advice to ensure the health of both mother and baby.
