Los Altos businessman convicted in $77 million fraud scheme

Mark Schena

A jury has found guilty a Los Altos businessman who was accused of lying to investors about inventing technology that tested for allergies and Covid using only a few drops of blood.

Mark Schena, 59, was convicted Thursday of paying bribes to doctors and defrauding the government after his company billed Medicare $77 million for fraudulent Covid and allergy tests, the U.S. Department of Justice said in a statement.

Schena, 59, claimed his Sunnyvale-based company, Arrayit Corporation, had the only laboratory in the world that offered “revolutionary microarray technology” that allowed it to test for allergies and Covid with the same finger-stick test kit, prosecutors said.

Alexandra Block, an attorney representing Schena, did not return a phone message seeking comment.

The case against Schena shared similarities with a more prominent legal saga surrounding former Silicon Valley star Elizabeth Holmes, who dropped out of Stanford University in 2003 to found Theranos, that she pledged would revolutionize health care with a technology that could scan for hundreds of diseases and other issues with just a few drops of blood, too.

As Theranos’ CEO, Holmes went on to raise nearly $1 billion from successful business leaders such as Oracle founder Larry Ellison and media mogul Rupert Murdoch. Holmes, now 38, was convicted on four felony counts of investor fraud in January following a nearly four-month trial in the same San Jose, California, courtroom where Schena’s trial was held.

Holmes faces up to 20 years in prison at her Oct. 17 sentencing.

The two cases intersected briefly Thursday morning when the jury deliberating in Schena’s trial sent three questions to Judge Edward J. Davila, triggering an hourlong delay in a hearing about Holmes’ unsuccessful attempt to overturn the jury’s conviction in her case.

A pivot to Covid testing

Prosecutors said that after Arrayit’s allergy testing business declined in 2020 amid the pandemic, Schena falsely announced that his company had a test for Covid based on its blood testing technology before even developing it.

After his company submitted it to the Food and Drug Administration, he did not disclose that the FDA concluded the test was not accurate enough to be authorized for emergency use, prosecutors said.

“Schena orchestrated a deceptive marketing scheme that falsely claimed that Dr. Anthony Fauci and other prominent government officials had mandated testing for Covid and allergies at the same time and required that patients receiving the Arrayit Covid test also be tested for allergies,” they said.

Schena also claimed that he was on the shortlist for the Nobel Prize and his test kits were more accurate than PCR tests.

Arrayit’s stock price more than doubled by mid-March 2020, even as the stock market was crashing, according to court documents.

Schena also failed to release Arrayit’s SEC-required financial disclosures and concealed that Arrayit was on the verge of bankruptcy, prosecutors said. The case against him was the first criminal securities fraud prosecution related to the Covid pandemic, they said.


Before the pandemic, from 2018 through February 2020, Schena and other employees paid bribes to recruiters and doctors to run an allergy screening test for 120 allergens ranging from stinging insects to food allergens on every patient whether they were needed or not, authorities said.

“Arrayit billed more per patient to Medicare for blood-based allergy testing than any other laboratory in the United States and billed some commercial insurers over $10,000 per test,” the DOJ said.

Schena was convicted of one count of conspiracy to commit health care fraud and conspiracy to commit wire fraud, two counts of health care fraud, one count of conspiracy to pay kickbacks, two counts of payment of kickbacks, and three counts of securities fraud.

  1. Mind numbing to have Theranos providing all the things NOT to do and then immediately repeating all the fraud again like it was a roadmap. Integrity people, keep a high level of integrity and you magically stay out of jail.

    • This guy isn’t some college drop out like Holmes. Check out his bio. My guess is that there’s more to the story. Hopefully he gets out soon with good behavior, as there are murderers in California who get lighter sentences.

      • So you’re defending this guy and hoping he gets off with good behavior because he has an impressive Bio? And you’re guessing “there’s more to the story?” He went to trial and was CONVICTED on the EVIDENCE of his crime. He committed fraud and he will need to do the time for it. The “story” was all laid out for a jury of his peers and they spoke. We need to rid the business world of LIARS and FRAUDS. Indicting and prosecuting them is a good first step. Please stop white-washing business fraud as if it isn’t a big deal, it’s a crime and should be punished accordingly. And please stop the what-aboutism comparing it to murder, it’s irrelevant to make the comparison and makes you come off looking very entitled.

        • Margaret,

          We shouldn’t defend any criminals. Criminals of all races, backgrounds, creeds should be appropriately punished for their heinous deeds. That’s true Justice.

          With this being said, which do you think is worse, murder or elaborate frauds by this man? I suppose it depends on your perspective and views.

  2. More to the story? It boils down to one thing. GREED. And the criminal justice system is too lenient on white collar criminals, which doesn’t help. In God we trust. All others are under intense scrutiny.
