Dr. Chen Zhe
The optimal time for Down syndrome screening is between the 15th and 20th weeks of pregnancy—a six-week window. Down syndrome screening is a method used to detect chromosomal abnormalities in the fetus; performing the test too early or too late may compromise the accuracy of the results. Therefore, it is essential to schedule the screening within this optimal timeframe to ensure reliable outcomes.
