What Are the Requirements for Donating Blood?

In the United States, someone needs a blood transfusion every two seconds. Blood donation is crucial to the healthcare system, saving countless lives every year. As January is National Blood Donors Month, it presents the perfect opportunity to remind individuals about the importance of blood donation and donor requirements. Let’s explore the requirements for donating blood and discover how this simple yet impactful gesture can make a difference.

The Importance of Blood Donation

Blood donation is vital for the survival and treatment of many hospital patients. Numerous procedures and conditions require blood. Here are some of the ways blood donation saves lives and promotes community prosperity:

  • Saving Lives in Emergencies. Many medical procedures, surgeries, and traumatic injuries require blood transfusions to keep a patient alive.
  • Supporting Medical Treatment. Treatments like chemotherapy also require blood transfusions to help patients recover post-treatment. 
  • Addressing Chronic Illness. Doctors may use blood transfusion to help individuals with chronic illnesses manage symptoms.
  • Maternal and Fetal Care. Complications during childbirth and c-sections often necessitate blood transfusions to address excessive bleeding and promote the safety of both mom and baby.
  • Public Health Preparedness. An adequate blood supply ensures that communities are prepared for emergencies like natural disasters or disease outbreaks.
  • Medical Research. Blood donation also supports medical research in blood-related disorders and diseases, helping researchers find new cures to save patients’ lives.

Blood donation is a crucial and life-saving act that directly impacts the health of medical patients. Becoming a blood donor allows individuals to take an active role in contributing to the health and well-being of their communities.

Blood Donor Requirements

There are several requirements you must meet to be able to join the 6.8 million blood donors in the US. Understanding these requirements ahead of time will help you make sure you’re ready for a trip to the clinic. Here are the requirements the American Red Cross sets for blood donation.

Donation Frequency

Blood can only be donated every 56 days or up to six times yearly. Creating blood can be taxing on the body. This requirement is set to allow your body to recover and produce new blood without over-exhausting your cardiovascular system. Donating too often can lead to iron deficiency and anemia. Keep track of your last donation date and schedule your appointments within these time limits. 


Most states require donors to be at least 17 years of age. However, many states allow donation at 16 years of age with parental consent. At the time of donation, individuals must present some form of identification to prove their age. One form of primary identification, like a driver’s license with a photo or passport with a photo, or two forms of secondary identification, like a birth certificate or credit card, may be used.


Donors must weigh at least 110 lbs to tolerate the blood loss. However, shorter individuals have different weight requirements. The shorter the individual, the more they must weigh. For example, a 4’10” female must weigh 146 lbs to donate blood. Call your local Red Cross location to check on your specific height and weight requirements.

Health Requirements

One of the biggest reasons an individual becomes ineligible for donation is health concerns. To donate blood, you must be feeling well and in good health. If you are experiencing any flu-like symptoms or fever, you are not eligible to donate. Those with chronic conditions that are being medically managed are still eligible for donation as long as they feel well. Pregnant women are ineligible for donation up to six weeks postpartum. 

Prior donation requirements stipulated that any international travel made an individual ineligible for donation. However, recent changes have been made to the requirements. Individuals should expect to be asked about travel outside the US and Canada within three years of their donation date. Depending on where and when an individual traveled, they may be ineligible for donation due to malaria exposure.

 Some other conditions can disqualify individuals from blood donation like: 

  • Having AIDS
  • Being HIV positive
  • Recent STI treatment
  • Showing symptoms of certain illnesses
  • History of drug abuse

Contact your local clinic with any concerns you may have about eligibility.

How to Become a Blood Donor

Donating blood is simple. The American Red Cross provides 40% of the nation’s blood and is one of the best ways to donate. Find a clinic or blood drive near you and contact them to schedule an appointment.

Once you’ve arrived at your appointment, you will be asked questions about your medical history, travel history, and personal information to determine your eligibility. Once approved, the process only takes about an hour from the time you sit down to the time you’re out the door again. Snacks and drinks help your body replenish energy and prevent fainting.

Blood donation is a selfless and life-saving act that contributes to the health and safety of individuals across the country. If you are eligible, we encourage you to become one of the millions of blood donors this January!
