What tests need to be done throughout the entire pregnancy?

Patient's question:

No

Doctor's answer:

Hello, generally speaking, around the first week of pregnancy, an ultrasound examination is needed to rule out ectopic pregnancy. At weeks 18-20 of pregnancy, it is best to have an amniotic fluid test and Down syndrome screening. An ultrasound examination should be done at weeks 20, 24, 28, 32, 36, 37, 38, 39, and 40 of pregnancy.
