Can I give blood?
Can you give blood? Find out what can affect blood donation eligibility, including age, health, medication, travel, tattoos and previous donations.
Many people are eligible to give blood, but there are circumstances that can mean you need to wait before donating or cannot donate.
Age and eligibility
The minimum and maximum ages for donating can depend on the blood service and whether you are a first-time or existing donor.
Your general health
You normally need to be well enough to donate safely. Temporary illnesses, infections and other health circumstances can mean that you need to postpone your donation.
Medication
Taking medication does not automatically mean that you cannot donate. Eligibility can depend on the medication, why you take it and your circumstances. Never stop prescribed medication in order to donate.
Travel
Travel can affect blood-donation eligibility because some destinations carry risks of infections that can be transmitted through blood.
Tattoos, piercings and medical procedures
Some tattoos, piercings, medical procedures and investigations can require you to wait before donating.
Pregnancy and giving birth
Pregnancy and recent childbirth can affect when someone is able to donate. Check the current guidance from your blood service.
