Most people who get the call to donate stem cells have never been to hospital for anything like this before. You’ve had the medical checks, the phone calls, the G-CSF injections, and now the actual day is here. The good news is the donation itself is the easy part. You sit in a chair, they hook you up to an apheresis machine, and your blood does a loop through a filter and back into your arm. The less good news is it takes four to five hours, and hospitals aren’t exactly known for their entertainment options.
Here’s what’s actually worth packing, what the hospital already covers, and a few things nobody tells you until you’re already sitting there.
What the hospital already takes care of
Before you start filling a bag, it helps to know what you don’t need to worry about. The donation team provides everything medical. The chair, the machine, the lines, the nurses watching your levels the whole time. Most hospitals also provide basic snacks, water, and tea or coffee throughout the day.
You’re not checking in for a camping trip. The hospital’s got you covered on the things that matter. What you’re packing is for comfort, not survival.
What’s actually worth bringing
You don’t need a suitcase. You need a day bag with the stuff that’ll make four to five hours in a hospital chair feel a lot less like four to five hours in a hospital chair.
Comfortable clothes are the obvious one. You’ll have a cannula in each arm for the duration, so both arms are mostly out of action. Trackies, a hoodie, layers you can adjust without too much shuffling. Hospitals run cold, then warm, then cold again. Dress like you’re planning a long flight, not a job interview.
Bring your phone, headphones, and a charger. Most people burn through a full battery before lunch. A power bank is worth its weight if there’s no power point near your chair. Load up a few shows or a podcast playlist before you leave home because hospital wifi isn’t something you want to rely on. That said, don’t stress about filling every minute. Some donors end up falling asleep in the chair, which is completely fine and apparently more common than you’d think.
Snacks help more than you’d think. The hospital provides food and drinks, but let’s be real, hospital food isn’t known for its five star rating. Having your own stash means you’re not relying on whatever turns up on the trolley. Muesli bars, fruit, chocolate, whatever you’d grab for a road trip. A water bottle with a straw lid makes life easier when you can’t exactly pour yourself a glass.
The stuff nobody mentions
Lip balm. Hospital air is dry, and you’ll notice it about an hour in. Thick socks, because your feet will get cold before the rest of you does. If you take any daily medication, pack it in your bag rather than leaving it at home and assuming you’ll be back in time.
Bring your ID. The team will need to confirm who you are before anything starts, so a driver’s licence or passport saves any awkwardness at check-in.
With both arms occupied, you’re relying on your support person or nurse for the little things. Water, adjusting your headphones, and yes, scratching your head. It’s not like you’re completely strapped in and can’t move at all, but anything that needs two free hands is temporarily off the table.
And if you’ve got questions you’ve been meaning to ask, write them down. It’s easy to forget once you’re in the chair and the day is moving. The donation team deals with this every day and they’re happy to talk you through anything.
Bringing someone with you
Most donation centres are fine with you bringing a partner, a mate, or a family member. They can’t do anything medical, but they can keep you company, grab you a coffee, and make the day feel a lot more normal. If you’re someone who’d rather just put your headphones in and zone out, that’s completely fine too. There’s no wrong way to get through it.

If you’re donating through bone marrow collection
Everything above applies to PBSC donation, which is how most stem cell donations happen. If your donation is through bone marrow instead, it’s a different setup. That involves a general anaesthetic and usually an overnight stay, so you’ll want to pack more like you would for a short hospital admission. Your donation team will walk you through exactly what to bring for that process, so follow their lead.
Ready to join the registry?
Most people who sign up to the stem cell donor registry never get called. But for the small number who do, being prepared makes the day a lot easier than it sounds.
If you’re aged 18 to 35 and haven’t joined yet, it starts with a simple cheek swab.
