A Missouri dad has a new lease on life, thanks to his daughter.She gave him her kidney, but she kept the entire process a secret because, at first, he wouldn't allow her to do it."I mean, I was upset but I'm so grateful. I mean, it's just, it's just hard to describe," John Ivanowski told KMOV. However, the emotion on his face says everything. "I can't stop crying," he said. "He goes, 'I knew you were up to something,' and I said, 'well, I'm always up to something," Delayne Ivanowski, John's daughter, said. That something began brewing in Delayne's mind more than a year ago after doctors told her father he had an immunoglobulin A deficiency, causing an overactive immune system to attack his kidneys. "From there, it's just been dialysis every couple of days since then. So for over a year, he's been hooked up to a machine for three, four, five hours a day. So then my first thought was, why can't he just have my kidney right now?" Delayne said. Her father was against it."I didn't want her kidney. I'm like, you're too young, you've got a long time to be here," John said. But Delayne had other ideas. "I don't even remember how I got his coordinator's phone number. And I reached out to her and I was like, 'hey, how can I do this, when can we start?' And then as soon as he was good enough basically for the transplant, they started running me through a bunch of tests," Delayne said. Eight months of secrecy all led to the moment on Feb. 16."I didn't find out until the day of surgery after we were post-op. She opened the door and came through and I was just like, 'oh my lord,'" John said. A moment tugging at millions of heartstrings after Delayne posted the video on TikTok, asking each of her followers to donate a dollar for her family's medical costs. "And I thought, why not reach out to like social media, and I got a way bigger response than I ever was expecting to," Delayne said. Her father was asked if he was now grateful that she did it. "Oh, I'm so grateful not to be hooked up to the machine anymore and be able to do what I need to do or what I want to do, you know, it's just gonna be, it's a big relief," John said. "It is one of the greatest gifts you can ever give," Delayne said.
