Donating blood for the first time can feel a little nerve-racking — but most donors find it straightforward and empowering. This guide walks you through eligibility checks, what happens at the donation appointment, and how to care for yourself afterwards.
Am I eligible?
Eligibility varies by country and centre, but common requirements include being in generally good health, meeting age and weight minimums, and not having recent infections or certain travel/medical histories. You will complete a short health questionnaire and a quick hemoglobin (iron) check before donating.
What happens at the appointment
- Registration: confirm ID and complete paperwork.
- Health check: a trained staff member measures temperature, blood pressure, and hemoglobin.
- Donation: a sterile needle collects about 450–500 mL of whole blood; the process takes 8–10 minutes for the actual draw.
- Recovery: you rest for 10–15 minutes with refreshments to help restore fluids and check you feel well before leaving.
Tips for first-time donors
- Eat a healthy meal and drink plenty of water before you arrive.
- Wear comfortable clothing with sleeves that can be rolled up.
- Bring ID and any donor card or medical information if requested.
- Plan light activity for the rest of the day and avoid heavy exercise for 24 hours.
Aftercare and follow-up
Keep the bandage on for a few hours, stay hydrated, and avoid heavy lifting with the donation arm on the day of donation. If you are advised of low hemoglobin, staff will give guidance — some centres recommend iron-rich foods or supplements for new donors.
