Genetic testing is a systematic diagnostic and screening technique usually applied to detect risk of genetic disorders in unicellular and multicellular organisms. This technique in a broader sense includes biochemical tests for the detection of possible presence of genetic diseases or mutant forms of genes associated with increased risk of developing genetic disorders. Genetic testing is broadly segmented as newborn screening, diagnostic testing, carrier testing, prenatal testing, pre-implantation testing, predictive and forensic testing. Prenatal and newborn genetic testing market is segmented on the basis of technology and geography. Prenatal and newborn genetic testing refers to the utilization of screening/diagnostic procedures of a fetus or a new born baby to detect chromosomal abnormalities such as Down syndrome, Patau syndrome and Edward syndrome.
The prenatal and newborn genetic testing market by technology is further segmented as diagnostic tests and screening tests. The diagnostic tests segment covers the global market for techniques such as polymerase chain reaction (PCR), fluorescence in-situ hybridization (FISH) and array comparative genomic hybridization (aCGH), while screening tests include non-invasive prenatal testing (NIPT) and maternal serum screening (MSS).
The prenatal and newborn genetic testing market is driven by increasing maternal age and late pregnancies, technological advancements and growing awareness about genetic disorders in the fetus.
Diagnostic tests are more effective, accurate and preferred option for detection of chromosome abnormalities compared to the screening methods. PCR technique accounted for the largest share among diagnostic tests category due to its varied applications and high efficiency. On the other hand, aCGH and FISH are most growing and developing diagnostic techniques owing to their high efficiency. While NIPT market (screening methods) is growing at a highest CAGR from 2013 to 2019.
North America is the largest market for prenatal and newborn genetic testing owing to the non-invasive nature of NIPT tests that completely eliminates the risk of miscarriage associated with invasive tests such as amniocentesis and CVS (Chorionic Villus Sampling). While Asia-Pacific market has a highest CAGR after North America as this market is driven by factors such as developing awareness about genetic testing, high prevalence of genetic diseases, increasing population and economic development. Rest of the World (RoW) is the untapped market due to lack of awareness, cultural barriers in the Gulf and African countries, and weak economic conditions in some African countries.
