Most important, Theranos tests cost less. Its prices are often a half to a quarter of what independent labs charge, and a quarter to a 10th of what hospital labs bill, with still greater savings for expensive procedures. Such pricing represents a potential godsend for the uninsured, the insured with high deductibles, insurers, and taxpayers. The company’s prices are set to never exceed half the Medicare reimbursement rate for each procedure, a fact that, with widespread adoption, could save the nation billions. The company also posts its prices online, a seemingly obvious service to consumers, but one that is revolutionary in the notoriously opaque, arbitrary, and disingenuous world of contemporary health care pricing.
