Ailing singer Natalie Cole is still in need of a new kidney after her son was rejected as a possible donor.
Cole, 59, has been battling ill health since she was diagnosed with Hepatitis C last year. She suffered kidney problems while undergoing treatment for the liver disease, and is currently undergoing dialysis three times a week.
The only cure is a kidney transplant - and her son Robert, 31, was checked out as a possible donor.
But Cole revealed on Tuesday night's Larry King Live show that her son has been ruled out - after doctors discovered he isn't a suitable candidate for organ donation.
She told King: "It's more than blood. Your general health has to be really, really good. There are some other requirements that they have.
"In other words, my son had some blood pressure issues. And they felt that that was a red flag."
But Cole's hope of receiving an organ transplant may still come to fruition - TV host King presented her with a pile of e-mails from viewers, offering her their own kidneys.
And the singer was overwhelmed by the response, telling King: "I always felt that it was just so strange to solicit to strangers for a kidney. But people are really great. There are some great human beings out there. That's all I can say." - Wenn
