There are different kinds of prenatal genetic screens:

• Serum Integrated Prenatal Screen (SIPS): 2 blood tests
• Integrated Prenatal Screen (IPS): 2 blood tests plus an NT ultrasound
• Quad Screen: 1 blood test
• Nuchal Translucency (NT) Ultrasound: may be offered as part of IPS or on its own

The prenatal screen you are offered depends on how far along you are in your pregnancy, your age, your health and family history and whether or not you are carrying more than one baby.  The earlier you see your health care provider, the more options you will have.
