TL;DR: for a kidney donation to a stranger, the health requirement for the donor is relatively high. The timescale for the whole process is on the order of months
Rigor: I didn't take detailed notes during the process, so am reconstructing this based on call/email logs and memories of conversations. I'm >80% sure I've hit all the major points, though the process may have changed recently. Happy to make edits if anyone has more up to date info.
Edit: A more thorough and up to date post on this topic can be found here
In the UK, the process of donating your kidney to a stranger is known as a 'non-directed altruistic donation'. There is some information online, certainly more than when I applied in 2020 but I thought I'd share my personal experience.
Non-directed altruistic donations are used in 'chains', where your donation would facilitate 3+ transplants.
You cannot legally sell your kidney in the UK, only donate.
The process is roughly as follows:
I personally did not make it past step 5. I was a reasonably fit and healthy 30 year old, but with a family history of cardiovascular disease and diabetes which meant I was too high-risk for a non-directed altruistic donation, but would have still been allowed to donate to a friend or family member.
Why they didn't screen for this earlier on in the process I don't know.
Communication was pretty disorganised, a lot of stuff was arranged over the phone only, with no follow up email/text, and no way of contacting anyone to confirm/rearrange/cancel.
Things took a long time to progress from one step to the next. I initially applied in August 2020, but did not speak to the psychologist until April 2021, with my final meeting with the renal doctor in July 2021.
I was told that the NHS would reimburse travel expenses but I didn't enquire into this.
Most availability for these steps are at the same time each week (eg. the slots for you to go to the hospital for tests are only Thursday afternoons). As you can imagine these are during work hours Monday-Friday.
Lots has been written about kidney donation through the lens of effective altruism (there's even a forum tag on the topic!), including a recent post which is what spurred me to write this post.
While I did like Alexander Berger's point of view, what resonated with me more was Dylan Matthew's argument, that while it may be more efficient for an individual to donate to charity (the time spent recovering from kidney surgery I could have instead worked and donated the money for more QALYs saved), donating a kidney could serve as a symbol and a talking point to influence those around me to create a kind of multiplier effect.
If anyone from Germany is wondering, just found out that it's not possible to donate a kidney "altruistically" in Germany. You have to be a direct relative or a spouse.
I just came across an interesting (and not too long) article on this point. Quoting the juicy parts:
