Four companies have brought noninvasive prenatal testing to the market within the past two years. Its dramatic, rapid uptake has triggered a backlash among many geneticists, who fear the consequences of a poorly understood – and overhyped – technology.

The recent launch of several noninvasive gene-based tests for Down syndrome and other fetal chromosomal abnormalities is poised to upend current prenatal screening practices and potentially usher in a new, multibillion-dollar market opportunity in the process. These new tests employ next-generation gene sequencing, along with advanced, risk-based computer algorithms, to detect and characterize fetal genetic abnormalities using the DNA present in a maternal blood sample. And because they are actually able to “interrogate” the DNA, they represent a huge technological advance over the current standard-of-care for prenatal screening.

Medical device companies raised $1.1 billion, a 40% increase over Q4 2011’s $800 million. Two billion-dollar deals in the resuscitation market boosted device acquisition activity to $4.2 billion.
