Software Glitch Falsely Alerts Hundreds They May Have Cancer

Grail, a company that developed a blood test to detect dozens of types of cancer, mistakenly told about 400 customers that they might have the disease due to a software configuration issue.
The problem was not caused by inaccurate test results, and more than half of the people who received the letter in error had not yet had their blood drawn for the test.
The vendor responsible for the mistake, PWNHealth, notified Grail about the issue on May 19 and addressed the underlying problem within an hour of becoming aware of it.
No patient health information was disclosed or breached due to this issue, and no patient harm or adverse events have been reported.
Grail's parent company, Illumina, is currently facing a regulatory battle with the United States and the European Union over its acquisition of Grail.
