Since ACOG recommends that all women be screened for T21 then it is more important how many pregnancies there are per year in the U.S. In 2005, an estimated 6,408,000 pregnancies resulted in 4.14 million live births, 1.21 million induced abortions, and 1.06 million fetal losses. The 2005 pregnancy rate of 103.2 pregnancies per 1,000 women aged 15–44 years is 11 percent below the 1990 peak of 115.8. This has remained at about the same level over the last 4 years. Of these about 80% are first evaluated in the first trimester - the first 12 weeks of pregnancy. So about 3.2 million women would be screened for T21. Therefore SQNM could potentially provide the screening test for around 3 - 4 million women per year if all chose to screen for T21 with a simple blood test. Daniel UCLA MD
Thanks for your numbers, however in an extremely consevative model I can only use documented cases that are "currently being screened for t21 and that is 200k amniocentesis are performed yearly in the USA.
There are 2 million syrum based tests at $500 however include screen for a host of other diseases and we cannot know if they will take the t21 alone for $800.
Daniel, Must the T21 test be offered alongside non-invasive T18 and T13 screens to completely obliterate the need for invasive tests? Or would there still be a need for invasive testing even with a non-invasive T21 screen?
