Genetic test market exploding with 10 new tests a day, study says

Dive Brief:

• The genetic test market has grown rapidly in the 15 years since the human genome was mapped, totaling about 75,000 different tests today. And each day, about 10 new tests enter the market, according to a new Health Affairs analysis.
• To better understand how genetic tests are used and paid for, the researchers reviewed unique data sources on test availability and private insurer spending from 2014 through 2017, looking in particular at tests that measure multiple genes.
• Prenatal tests constitute nearly 40% of genetic test spending, followed by hereditary cancer tests at 30%. A little more than 10% of spending is for tests related to cancer diagnostics and treatment.
