Pre pregnancy genetic screening costs

Between the four new tests, Verinata’s and Sequenom’s currently offer the widest range of screening options, with the ability to identify disorders associated with an extra X or Y sex chromosome, such as Klinefelter’s (XXY) and triple X syndrome. For now, the DNA-based tests are only thought to provide a screening tool for select populations, and are not considered definitively diagnostic by clinician groups such as the National Society of Genetic Counselors, who worry about the possibility of erroneous results, the lack of data in low-risk populations and the limited number of aneuploidies tested. I believe that if more research could be conducted on these types of tests in order to improve their accuracy, and if they could be made more cost effective, these types of tests would be a great success within the medical field. Dr David Amor, Director, from Victoria Clinical Genetics Service has presented at the Obstetric Malpractice Conference.


Wrongful birth litigation may occur following birth of a childwith a genetic disorder when1. With US health insurers, including Aetna and Wellpoint, saying they plan to cover the new tests, the market for DNA-based prenatal screening now provides “a billion dollar opportunity,” according to David Ferreiro, an analyst at Oppenheimer & Co. This flexibility is reflected in the cost: Sequenom’s MaterniT21 PLUS carries a list price of $2,762, almost twice as much as Natera’s Panorama, which can detect a missing X chromosome but not other kinds of sex chromosome irregularities. Nanomedicine is the furture hope for the curative treatment of cancers and other genetic disorders.


Although the additional testing will still mean invasive procedures for some pregnant women, and their attendant complications, “you are limiting those invasive tests to only the high risk groups,” says Joan Scott, a genetic counselor and executive director of the National Coalition for Health Professional Education in Genetics in Lutherville, Maryland. So many people would be carriers for at least one diseasethat genetic counselors might be overloaded.
