The quad screen is usually done between 15 and 20 weeks of pregnancy. You'll have a blood sample taken and sent to a lab for analysis. Results are usually available in about a week. The test measures the levels of four substances in your blood: 1  alpha-fetoprotein (AFP), a protein made by the baby.
This test is however only 99.1% accurate and an amnio is recommended following the blood test if results are positive. My quad screen came back clean but my 20week scan showed a soft marker for down syndrome. We are consulting with the perinatologist next week but will likely do the amnio at that time to be sure.
