What is the First Trimester Screening?2022-05-23T13:12:14+00:00

The First Trimester Screen is a method of screening for Down syndrome, Trisomy 18, and sometimes Trisomy 13. It involves a specialized ultrasound and a blood test at 11-13 weeks of pregnancy.

Is the First Trimester Screening Test for all women or just those who are over 35?2022-05-23T13:12:14+00:00

The risk for a chromosome abnormality increases as women gets older. However, any pregnancy can be affected by a chromosome disorder. Therefore, pregnant women of all ages are encouraged to have a First Trimester Screen. Women who are over 35 years of age may also consider diagnostic testing through CVS or amniocentesis.

Do I still need another blood test after the First Trimester Screen?2022-05-23T13:12:14+00:00

Yes, all women should consider completing a blood draw that measures a protein in their blood called AFP that screens for spina bifida and related conditions. This occurs around 16 weeks of pregnancy.
