The embattled blood-testing startup company, Theranos, is planning to shut down its Scottsdale laboratory and five metro Phoenix wellness centers. The move has been taken to focus on developing its laboratory technology.

The company's founder Elizabeth Holmes said in  a statement posted to the company's website, that, the company has decided to close its clinical labs and Theranos Wellness Centers. The company's Valley clinical lab is located at Arizona State University's SkySong office complex in Scottsdale.

The closings will eliminate about 340 positions in Arizona, Pennsylvania and California. The Silicon Valley company's largest retail presence has been in Arizona, where it operates five testing centers as well as the clinical lab.

Holmes' statement did not address whether the company still plans to appeal the certificate revocation.

"After many months spent assessing our strengths and addressing our weaknesses, we have moved to structure our company around the model best aligned with our core values and mission," Holmes said in the statement.

"We will return our undivided attention to our miniLab platform. Our ultimate goal is to commercialize miniaturized, automated laboratories capable of small-volume sample testing, with an emphasis on vulnerable patient populations, including oncology, pediatrics, and intensive care."
