There are several requirements for assessing donor eligibility in addition to the donor history questionnaire, such as age, height, and weight.
Age requirements are set by each state, with most requiring a minimum age of 16 with parental consent to donate blood products, and others requiring donors to be at least 17 years old. There is no upper age limit to donate blood, but some blood centers use their own discretion and coordinate with physicians for donors of advanced age.
The Food and Drug Administration (FDA) requires all donors to weigh at least 110 pounds (50 kilograms) regardless of age, height, or gender. Some blood centers may use their own discretion to employ more strict parameters for weight based on individual circumstances.
