Global Prenatal & Maternal Diagnostic Market 2016
DecisionDatabases.com announces a new report “Global Prenatal & Maternal Diagnostic Market To 2021” added to its database. The report provides key statistics on the current state of the industry and other analytical data to understand the market.
Prenatal tests (fetus, embryos and newborns) currently on the market analyze chromosomes, DNA, RNA, genes, and/or gene products to determine whether an abnormality is present that is causative of a specific disease. Since 2011, the launch of noninvasive prenatal tests (NIPTs) is revolutionizing the prenatal screening industry providing detection rates of >99% and false positive rates of <0.1%. These screening results are only indicative of the risk and not confirmative. To confirm positive results of NIPT screening tests, prenatal diagnostic tests such as amniocentesis and chorionic villus sampling (CVS) are performed. Prior to NIPTs, ultrasound and maternal serum tests were routinely used to screen fetusus for genetic abnormalities.
Globally, 50 countries have effective newborn genetic test programs, the implementation of which is in various stages. In the U.S., four million newborns are tested annually, with 3,000 found to have metabolic and genetic diseases. The purpose of newborn screening is to identify affected newborns quickly and provide them with treatment to prevent mental retardation, prolonged illness and death. The newborn genetic screening market is crowded with different technologies, the common being tandem mass spectrometry, pulse oximetry, enzyme-based assays, DNA assays and electrophoresis.
Preimplantation genetic screening and preimplantation genetic diagnosis (PGS/PGD) are genetic tests performed in eight-celled embryos before implantation during in vitro fertilization (IVF) for the detection of genetic abnormalities and ***. These tests can detect and diagnose chromosomal rearrangements, X-linked diseases and help in reducing the incidence of spontaneous abortions, increase implantation rates, prevent trisomic offsprings and avoid the risk of transmitting single gene disorders. However, PGS and PGD results are not 100% accurate and after pregnancy, if required the diagnostic tests such as amniocentesis and CVS are to be performed to confirm the positive results of PGS/PGD. In the U.S. alone, more than 63,000 babies were born through IVF in 2013 and compared to 2012 data; it was an increase of 2,000 births.
The most important development in the field of prenatal screening, is the introduction of NIPTs using cell-free fetal DNA (cffDNA) in 2011. Obstetricians and patients who are deterred by the 10% to 15% false positive rates of ultrasound screening and 5% false positive rates of maternal serum tests are eagerly embracing NIPTs which claim to have only <0.1% of false positive results.
