Distribution of blood donor deferrals in the United States in 2019 and 2021, by reason
Data is from the National Blood Collection and Utilization Survey (NBCUS).
* Donors deferred for low hemoglobin included those that do not meet the current FDA blood hemoglobin level requirements for blood donation.
** Other medical reasons may include the use of medications on the medication deferral list, growth hormone from human pituitary glands, Hepatitis
B Immune Globulin (HBIG), unlicensed vaccines, or presenting with physical conditions or symptoms that do not qualify a person to be a
blood donor.
*** High-risk behavior deferrals include deferrals intended to reduce the risk of transmission of infectious diseases including HIV and hepatitis
viruses. Examples of questions intended to identify these risks are sexual contact (men who have sex with men [MSM]) and non-medical
injection drug use questions.
