Ms Wilharm said that the heartbreaking news that her grandfather was dying hurt even more delivered through a machine.
As her grandfather had a hearing problem, she had to relay the news, KTVU reported.
"I was going to lose my grandfather", she told KTVU.
"I was so scared for him and disappointed with the delivery", Wilharm said, choking up. "I didn't think he'd get his death sentence here". "It should have been a human being come in".
Annalisia shot the encounter on video, thinking at first that she could share the test results with her family.
Mr Quintana's daughter, Catherine, told KTVU that the family was further upset because her father had trouble hearing the doctor through the speakers, forcing Ms Wilharm to relay the bad news.More news: Ex-Raven Mosley to sign with Jets

"If you're coming to tell us normal news, that's fine, but if you're coming to tell us there's no lung left and we want to put you on a morphine drip until you die, it should be done by a human being and not a machine", Catherine Quintana told USA Today.
Wilharm told CNN that her family was under no illusions about her grandfather's condition.
Kaiser Permanente Senior Vice-President Michelle Gaskill-Hames issued a statement following the passing of Mr. Quintana nearly a week later.
Gaskill-Hames added the machine visit was a follow-up to earlier physician visits. She said she and her family hope no one else receives the same treatment.
She continued that the technology allows a small hospital to "have additional specialists" assist with patient care around the clock. "This secure video technology is a live conversation with a physician using tele-video technology, and always with a nurse or other physician in the room", Kaiser Permanente said.
A spokeswoman for the hospital offered "sincere condolences to the family" in a statement sent to CNN.
Steve Pantilat, chief of the palliative medicine division at University of California, San Francisco, said he did not know the details in the case, but that robot technology had done wonders for patients and their families, some of whom were too far away for in-person visits.
