A new kidney would change my life, but I'd rather wait ten years than win one like this.Libby Manship, 53, from Birmingham, developed kidney failure two years ago and desperately needs a transplant.
Here she gives her views on the reality TV spectacle.
There are three words to describe this programme: unethical, abhorrent and diabolical. The premise makes a complete mockery of everything I and all the other sufferers of kidney failure go through every day.
Our lives are hell - day upon day of dialysis, four hours each time at a machine, a restrictive diet and constant exhaustion.
A show such as the one being made by Endemol trivialises the struggles we face every day.
Anguish: Kidney patient Libby Manship.
There are lives at stake and fragile people involved.
Our lives are not to be made light of, with text-in votes and a competition to see who "deserves" a kidney the most.
Imagine if you were desperate for a kidney, as I am.
It isn't just a lifeline, it is a whole new life - free of constant illness and the possibility of death, not just for you but for your whole family: children, husbands and wives who depend on you.
Then imagine that having built up so much hope and expectation - and having laid your life and emotions bare in front of millions of viewers - it is all snatched away, with your anguish writ large for all to see.
I know we live in an amoral age where reality TV offers people the chance of instant wealth, an instant spouse, or even an instant course of IVF.
But this programme is different - it is risking people's lives.
In order to have a transplant, patients are put on immuno-suppressant drugs for a month to prepare their bodies for the new organ.
This in itself is hugely dangerous - patients are at risk from a whole host of diseases.
Why a production company would want to film something as debilitating as that is beyond me - it degrades the patients and their families at a time when they are literally fighting for their lives.
Two years ago, I too was forced to face up to a bleak future when I was diagnosed with kidney failure.
In October 2005, my husband David and I, both retired, booked a holiday to a secluded beach spot in Ibiza.
A few weeks before the holiday I went for a routine blood test.
I suffered occasionally from fibromyalgia (a disease which causes my joints and muscles to ache) and needed to take anti-inflammatory medication to lessen the pain.
As a result, the doctors liked to keep a check on my blood.
But three hours after I'd returned home the hospital called and they were frantic. I'll never forget what the doctor told me.
She said: "We have a bed waiting for you. You need to come back immediately. You are in complete renal failure."
My husband drove me straight back to the hospital, where more tests were performed.
Over the course of that night it emerged that one of my kidneys had failed when I was eight.
My other kidney, which was already underdeveloped, was required to do all the work. Because of its small size, it had completely worn itself out.
And to top it all off, the anti-inflammatory drugs I'd been taking for my fibromyalgia had hastened my kidney's demise.
My situation was so critical that within three weeks I had been put on dialysis ( doctors normally wait five to six weeks to see if the kidney can regain function or "live" off special antibiotics), and a kidney donor was essential.
My family and friends rallied round, but no one was a match.
David, my husband, was desperate to be tested, but he's 67 and I didn't want to take the risk of him donating an organ to me.
Although doctors referred me immediately to the transplant list, it was very difficult to get on.
Patients need a year of tests and it was only four months ago that I was finally passed to join the register.
I know what it feels like to put your life on hold, to start a day with expectation that your life could change for ever, only to have your hopes dashed.
That's why, when I heard about the new 'Big Brother' style show, I was so appalled. It isn't easy to go through a year of tests, just to get approved by the transplant list, but it is sensible and safe.
Why producers would want to bypass this to create such a callous gameshow in the name of entertainment staggers me.
Firstly, what if they haven't had all the proper screening required by a legitimate transplant list? There would then be no guarantee that the kidney would be the absolute correct match.
Also there is always a chance that the kidney is rejected and the patient loses their life - how could a television programme want to show that?
Are they ready to accept that responsibility, or will they try to wriggle out of it if something goes calamitously wrong?
And before anyone accuses me of being jealous of these three people with the chance of a new life, believe me, I would never accept a kidney if it meant getting it on a reality show.
The hardest thing that I have had to accept with my own place on the donor register is that my age stands in my way.
I have, perhaps, a maximum of ten more years on the register.
If I survive to 63 (on dialysis and without a donor) I will probably be judged too much of a health risk.
So, yes, in an ideal world I would love to find a match. But on TV? Never.
This is no way to raise the important issue of encouraging kidney donors. They should be ashamed of themselves.
