Testing company's error causes cancer scare for hundreds
More than 400 people who signed up for Grail Inc.'s early-warning cancer test were mistakenly told they likely had the disease due to a "software configuration issue" by telemedicine vendor PWNHealth. The warnings were sent to half of the trial testing participants, some of whom had not even had their blood drawn yet. Grail confirmed that the software mishap had been resolved and was not related to an incorrect Galleri test result. The mistake has caused concern among some insurers involved in the trials.
