Spokane, WA 4/30/14—The Spokesman-Review has reported that PerkinElmer will close its Signature Genomics business later this year. Signature provides microarray-based prenatal and other genetics testing services. PerkinElmer told the Spokesman-Review, “Changing market conditions, including a highly unfavorable reimbursement environment, combined with a significant decline in demand for invasive procedures due to the uptake of non-invasive prenatal testing, contributed to this decision.”
