This article is undergoing editorial and medical review. We regularly update content as part of our commitment to providing patient-centered, accurate, evidence-based information.
Overview
Your donation day is when everything becomes real. Professional staff support you through the entire experience. For apheresis collection, you sit in a comfortable chair for 2-4 hours while the machine collects your stem cells. For bone marrow recovery, you have brief surgery under general anesthesia.
Your support person can wait with you before collection and meet you right after. Having someone there helps many donors feel calm and less anxious. Hospital staff know how to manage pain and keep you safe during recovery. You are not alone on this important day.
What to expect on collection day
Donation day brings everything you've prepared for into reality. Your body is doing what was planned; medical professionals are supporting you; the recipient is getting their new start. This day can feel momentous and nerve-wracking. Knowing what to expect helps you feel more prepared.
Arrival process. When you first arrive:
- Arrive 1-2 hours before scheduled procedure
- Check in with ID and insurance information
- Change into a hospital gown
- Meet your healthcare team (nurse, physician, coordinator)
- Brief vital sign assessment
- Ask final questions now
What to expect at the site
When you arrive, you'll check in and move to the pre-procedure area. You'll change into a hospital gown and meet your healthcare team: your nurse, the collection physician, and sometimes your coordinator.
Your vital signs (blood pressure, heart rate, temperature, oxygen level) will be checked. You'll answer questions about medications, eating, or any last-minute concerns. This is a good time to ask final questions or tell your team about anxiety you're feeling.
Your support person can stay with you through most of the pre-procedure process. They can be present until you go into collection, and will be waiting when you emerge. Their presence often helps you feel calmer and more grounded.
PBSC collection day
PBSC collection process. What you'll experience:
- You're taken to apheresis area with comfortable recliners
- IV lines placed (one or two depending on access)
- Apheresis machine set up (takes 10-15 minutes)
- Collection session runs 2-4 hours total
- Nurse checks on you regularly
- You can watch TV, read, listen to music
You'll sit or recline in the chair while the machine collects your stem cells. Your nurse checks on you regularly—are you comfortable, do you need anything, how are you feeling? Many people find the time passes faster than expected.
After collection, needles are removed and bandages placed. You'll rest briefly and be offered food and drinks. You should feel well enough to go home the same day, though you'll be tired.
Post-collection care. Immediately after:
- Soreness at needle insertion sites (usually mild)
- Bruising develops at needle sites
- Use ice first 24 hours, then heat
- Over-the-counter pain medication helps if needed
- Support person drives you home
- Most soreness resolves within a few days
Bone marrow hospital stay
Overnight stay
Admission steps. Your initial hospital experience:
- Admitted to hospital room
- Meet your nurse and get oriented
- IV line placed (if not already done)
- Change into hospital gown
- Process takes 30-60 minutes total
You'll be taken to the operating room where you meet your anesthesia team. They ask final questions about medications, allergies, or previous anesthesia reactions. Discuss any anxiety you have. You receive pre-medication to help you relax through your IV. Then you're wheeled to the operating room.
Operating room setup. What happens:
- Moved to the operating table
- Heart monitor leads placed on chest
- Oxygen monitor placed on finger
- Blood pressure cuff applied
- IV placed and anesthesia induced
- You likely won't remember induction or waking—just talking with anesthesiologist and then recovery
Discharge
After collection, you'll wake up in recovery and move to a hospital room for overnight monitoring. You'll be monitored for pain, infection signs, and anesthesia complications. Pain medication is given every 4-6 hours. You'll be encouraged to move—sitting up, walking, gentle movement—to speed recovery and prevent blood clots.
Overnight care. During your hospital stay:
- Pain monitoring and medication management
- Vital sign checks regularly
- Movement encouraged (prevents blood clots)
- Bathroom assistance provided
- Your support person can stay with you
- Overnight stay in hospital room
That evening or the next morning, the physician will evaluate you for discharge. Most donors are discharged the next morning. You'll receive discharge instructions covering pain management, activity restrictions, wound care, and follow-up appointments.
Discharge paperwork includes pain medication prescriptions and activity restrictions (usually no heavy lifting >5 lbs for 2 weeks). Your support person will drive you home. You'll need to rest for the next 2-4 weeks.
Who will be with you?
Your support person can be with you for most of the hospital experience. They stay with you during pre-op and wait until you go into collection. After collection, they'll be waiting in the recovery area. Their presence helps you feel supported and less anxious.
Support person role. They help by:
- Stays with you during pre-operative area
- Waits for you in recovery after collection
- Helps with practical needs (bathroom, positioning)
- Obtains pain medication for you
- Monitors recovery for bone marrow donors
- Assists with daily activities during recovery
Medical staff supports you throughout your stay. Your nurses are trained in donor care and have supported hundreds of donors. Your physicians manage your medical care. Your coordinator orchestrates everything and serves as your liaison to the transplant team.
Don't hesitate to ask for help with anything you need during your hospital stay. Call your nurse for pain medication, help with the bathroom, or just to talk. You're there because you're doing something generous, and the hospital staff respect that.
Going home
When discharge is approved, you'll change back into your clothes. Wear loose, comfortable clothes collection day since pain or bruising might make movement restrictive. You'll receive discharge paperwork with activity restrictions, pain medication, and follow-up information.
Your support person drives you home. Rest at home for the first few days, then gradually increase activity as tolerated.
Home recovery. What to expect:
- Expect fatigue for 1-2 weeks (from mobilization and collection)
- Follow activity restrictions from discharge paperwork
- No heavy lifting (usually >5 lbs for 2 weeks)
- Use ice first 24 hours, then heat for soreness
- Take pain medication as directed
- Keep puncture sites clean and dry
- Listen to your body—don't push beyond capacity
Follow-up appointments. You'll need:
- Blood work usually 1 week post-collection
- Phone check-in around 2 weeks post-collection
- Contact your center immediately for fever, severe pain, excessive bleeding, inability to walk, or other concerning symptoms

Hospital stay logistics
Room type and amenities. Most donors are placed in standard hospital rooms, sometimes shared, sometimes private depending on hospital availability. The room has a bathroom, TV, phone, and bell to call staff. Many hospitals allow visitors or support persons to stay; policies vary. Some hospitals provide cots or recliners for visitors to rest comfortably.
Meal planning. Post-operative diet usually starts with clear liquids (water, broth, juice) the evening of collection, advancing to regular diet as tolerated the next day. Most donors transition to regular food quickly if nausea isn't severe. Special dietary needs (vegetarian, allergies, religious restrictions) are accommodated with advance notice.
Post-operative vital sign monitoring
Monitoring frequency. Vital signs are checked every 1-2 hours during the immediate post-op period, less frequently as recovery progresses. Heart rate, blood pressure, temperature, oxygen level, and pain rating are assessed. Vital signs guide decisions about readiness for discharge—typically, donors should be hemodynamically stable with normalized heart rate and blood pressure before discharge.
Activity and wound care post-discharge
Restricted activity. Most bone marrow donors are restricted from heavy lifting (>5-10 lbs) for 2 weeks, strenuous exercise for 3-4 weeks, and contact sports for 4-6 weeks. PBSC donors typically have fewer restrictions—usually returning to work within 1-2 weeks. Individual variation means your coordinator will give you specific guidance.
Puncture site care. Keep the small puncture sites on your back clean and dry. Steri-strips or bandages can be removed after a few days. Shower normally (water over the sites is fine). If you notice signs of infection (increasing redness, warmth, pus, fever), contact your doctor. Infection is rare but should be evaluated promptly.
