A selfless firefighter has gone above and beyond the call of duty by donating his kidney to save a complete stranger's life.

Doctors at Duke University Hospital in Durham, North Carolina, removed a kidney from 41-year-old Edgewater firefighter David Blair on November 15.

Mr. Blair said he was inspired to under-go the surgery after seeing a heartbreaking social media post by Garry Hughes, seeking desperate help for his ailing daughter.

The firefighter took a survey through the hospital's organ transplant website and then a series of follow-up tests.

The 33-year-old recipient of his incredible gesture, Heidi Hughes, was a perfect match for Mr. Blair's organ.

The surgery was a success and Blair is now at home recovering.

Heidi Hughes, from Colorado Springs, who was born with cystinosis - a rare metabolic disease - is very thankful to David and says she intends to take good care of his gift.

She told Wesh 2 News: 'Kidneys are the first one to reject. So I had my first kidney transplant in 2002. It was donated by my dad.'

But unable to act as a live donor again, retired firefighter Garry took to social media to find another match for Heidi.

And shortly after, a fellow firefighter from Edgewood, Florida answered the call.

'I think it comes with my profession as a firefighter. That's what we do. Someone calls us, we go in and we help them, no matter who they are,' Blair told Wesh 2 News.

David insists saving lives comes as part of his responsibility as a firefighter. The 41-year-old poses for the camera with his family at Edgewater Firestation, in Florida.

The two firefighters knew each other vaguely from working at Daytona Speedway in the past, but Blair had never met Heidi.

'I've grown up in church, and love one another is something that's always been preached.

'Love conquers all. I don't look at it as a stranger or a family member. It's just somebody in need,' Blair said.

Heidi and David met face-to-face for the first time for dinner the night before the transplant.

Blair said: 'We just had a good time, and I got to meet her and we talked about the whole process.

'It was an emotional time, but it was great to finally meet her.'

Miss Hughes added: "I was so happy I got to give him a big hug before the transplant."
