Theranos has endured a spate of bad news lately. Most recently, a study from the Icahn School of Medicine at Mt. Sinai showed that Theranos blood test results differ from those of other blood-test companies.

But now Theranos, which disputes the results of that study, is calling up some heavy hitters: It's announced that a slate of healthcare professionals are joining its scientific and medical advisory board. Theranos, which is developing technology to allow hundreds of blood tests to be performed with just one drop of blood, is run by founder Elizabeth Holmes and has been valued at more than $10 billion.

Theranos has long been quizzed about its board of directors, which includes some impressive government figures--George Schultz and Henry Kissinger, for starters--but for long was light on medical expertise. The board of directors did include former Senator Bill Frist, who was a transplant surgeon before getting into politics, and William Foege, the former director of the U.S. Centers for Disease Control and Prevention.

The company says it is expanding its board after hosting three sessions in Palo Alto during which independent experts had full access to its systems, devices, data, and proprietary technology.

Theranos did not say if the new board members also visited Theranos' labs in Newark, California, which were recently subject to a report from a government agency that found them to be lacking in many ways. When the report was released, Theranos responded that it had already released a plan to fix the problems.

Theranos scientific and medical advisory board now includes:

Susan Evans, former president of the American Association for Clinical Chemistry

Bill Foege, former director of the U.S. Centers for Disease Control and Prevention

Ann M. Gronowski, department of pathology and immunology and the department of obstetrics and gynecology at the Washington University School of Medicine in St. Louis

David Helfet, Hospital for Special Surgery and New York-Presbyterian Hospital, Weill Cornell Medicine

Larry Kricka, University of Pennsylvania

Jack Ladenson, Washington University School of Medicine

Andy O. Miller, Hospital for Special Surgery and New York-Presbyterian Hospital, Weill Cornell Medicine

Steven Spitalnik, Columbia University Medical Center
