Most people can give blood. If you are generally in good health, age 17 to 65 (if it's your first time) and weigh at least 50kg (7st 12Ib) you can donate. However, If you are female, aged under 20 years old and weigh under 65kg (10st 3lb) and are under 168cm (5' 6") in height, we need to estimate your blood volume before donating.
Good news, your estimated blood volume is more than 3500ml, meaning you are able to give blood.
Sorry, your estimate blood volume is less than 3500ml, unfortunately you are unable to donate until after your 20th birthday.

There is no medical reason for an upper weight limit. However, our current donation beds and chairs are designed to safely accommodate a person weighing up to 25 stone (350 lb or 158 kg). You will need to be able to get on and off the donation bed or chair unaided or, if you have mobility problems, to bring someone along to assist you.
If you are unsure please feel free to call our 24 hour donor helpline on 0300 123 23 23.
Male donors can give blood every 12 weeks. That's approximately every 3 months or 4 times in a 12 month period. Female donors can give every 16 weeks or approximately every 4 months.
