You must weigh at least 50kg (7 stone 12 lbs) for blood donation. This is so the volume of blood donated will be less than 15 per cent of your circulating blood volume. Taking a greater proportion would cause problems because the body would not be able to adjust quickly enough.

The average adult has around five liters of blood in their body. When you donate whole blood (the traditional donation method) the target is to collect 500ml, but a minimum of 460ml is taken due to dosage requirements and necessary anticoagulant additive mix proportions.
After a donation, most people's haemoglobin levels are back to normal after 6 to 12 weeks. This is why we ask donors to wait for a minimum of 12 weeks between donations (12 weeks for men and 16 weeks for women) to ensure that we don't risk lowering your haemoglobin levels over the long term.
Blood donation leads to increased collagen synthesis and decreased collagen degradation, which are associated with the reduction of iron deposits in elderly skin. Our results indicate that appropriate blood donation has potential to be an anti-skin-aging strategy.
A tattoo is acceptable if the tattoo was applied by a state-regulated entity using sterile needles and ink that is not reused. Cosmetic tattoos (including microblading of eyebrows only) applied in a licensed establishment in a regulated state using sterile needles and ink that is not reused is acceptable.

00:00 Bill Rogers Deep veins are difficult to visualize and palpate on a person who is obese because of the extra layers of fatty tissue. Tourniquets must be tight enough to compress the vein, but often they are not able to exert the amount of pressure needed.
The amount of blood in a person's body depends on their size (the bigger the person's body is, the more blood it will contain). A newborn baby's body will contain only around a cup of blood whereas a 150-180 lb. adult will have approximately 1.2-1.5 gallons (or 10 units) of blood in their body.
