Ultrasound uses sound waves to create black and white visual images. A level II obstetric ultrasound is a detailed examination of the baby. Generally, this exam is done between 18 and 20 weeks of pregnancy. It is a painless, non-invasive test which does not harm the baby.
During the ultrasound, a Crozer-Keystone specialist carefully looks at the baby’s anatomy. This is to ensure the baby is growing and developing as expected.
An ultrasound can help confirm the age of the baby, and whether twins are present. Knowing the correct age of the baby is important when interpreting a woman’s MSS result. The accuracy of ultrasound dating is not exact but it is a good estimate. Ultrasound dating at 18-20 weeks of pregnancy can be off by approximately 1 week either way.
