First Trimester Screening What is First Trimester Screening? First Trimester Screening combines precise and specialized ultrasound with special blood biochemistry tests to identify high risk pregnancies. This is done approximately 10 and a half weeks to 13 and a half weeks. Isn't this routine when I have an early ultrasound? No. Special training and certification are required to be proficient in this unique ultrasound. What is the ultrasound looking for? All babies have a certain amount of fluid seen behind the neck early in pregnancy. Babies with Down syndrome may have an increased amount of this fluid. How accurate is First Trimester Screening? The combination of ultrasound and biochemistry will detect 90% of fetuses at high-risk of Down syndrome. This is compared to current 65-75% detection with Second Trimester Screening. Remember that this is not a diagnostic test and that not all babies with Down syndrome will be detected. OriGens can help make this very important distinction. Is Down Syndrome the only thing First Trimester Screening detects? No. Trisomy 18, other chromosomal errors, some congenital heart defects, and other more rare genetic disorders may be identified with First Trimester Screening. Will my insurance cover the cost of First Trimester Screening? Check with your doctor and/or insurance provider to see if your plan covers the consultation and any appropriate testing. Some patients may also prefer to pay cash and submit a bill for reimbursement as to not delay an appointment. |
