Nuchal translucency testing and serum screening can be performed in multiple gestations, but they are less sensitive than first-trimester screening in singleton gestations.Ĭombination of nuchal translucency testing, serum measurement of PAPP-A and free or total hCG, and maternal age Women who pursue first-trimester screening alone should be offered maternal serum AFP testing in the second trimester to screen for neural tube defects. Genetics counseling and chorionic villus sampling or amniocentesis should be offered to all women with elevated risk, as determined by serum screening. Women with isolated nuchal thickening or isolated maternal serum AFP (with normal ultrasonography and normal karyotype) should be followed closely because they are at increased risk of poor pregnancy outcomes.Ĭombined first- and second-trimester screening offers superior detection rates while maintaining low false-positive rates. Quadruple screening is recommended for second-trimester screening. Pregnant women should be offered screening and invasive diagnostic testing regardless of age.Ĭombined testing is recommended for first-trimester screening. Specific screening tests will depend on availability of the procedure and patient preference. Comprehensive counseling should be available to all pregnant women. For women who do not present until the second trimester, the quadruple screen is recommended. If nuchal translucency testing is unavailable, the maternal serum-integrated test is safest and most effective. An integrated test with nuchal translucency testing is the most effective method for women who present in the first trimester. These options include an analysis of pregnancy-associated plasma protein A, with or without nuchal translucency testing, in combination with quadruple screening. Patients may also choose a combination of first- and second-trimester screening in an integrated, stepwise sequential, or contingent sequential fashion. Screening options in the second trimester include serum screening using triple or quadruple screening, and ultrasonography. Nuchal translucency testing alone is not as effective. Screening options in the first trimester include nuchal translucency testing in combination with measurement of pregnancy-associated plasma protein A and human chorionic gonadotropin. Diagnostic options include chorionic villus sampling in the first trimester and amniocentesis in the second trimester. New developments in screening methods have increased the number of options for patients. ![]() You could do the method of the sequential screening, and then doing the panorama if you get a high risk result though - many people do opt for that since most insurances will automatically pay for the sequential screening anyway.Pregnant women of all ages should be offered screening and invasive diagnostic testing for chromosomal abnormalities before 20 weeks’ gestation. I would definitely call Natera though about payment estimates, and cross check that with what your insurance told you, just so that you know what to expect when you get billed. Totally worth the peace of mind, simplicity and quick return of info for us. I wasn’t high risk, so my insurance denied the claim (which I knew would happen) and just paid around $200 out of pocket. ![]() ![]() In our case, I was the most worried about false negatives, and I wanted to know information as early as possible (NIPTs can be done as early as 9/10 weeks), so that’s what we went with. The NIPT (natera panorama in this case) is more accurate and gives less false positives and false negatives.
