13 Things You Should Know Before Donating Blood
Donating blood is an incredibly noble cause, however there are some things you should know before you hand your arm over.
In the United States, a blood transfusion is needed every two seconds
It's estimated that one in seven people entering a hospital needs blood, according to The Red Cross. To keep up with this demand, the American Red Cross must host over 500 blood drives a day to collect nearly 13,000 units needed for hospital patients.
Not everyone is eligible to donate blood
The basic requirements include being at least 17 years old to donate, but some states allow you to be 16 years old with parental consent, weighing at least 110 pounds (however, there is a height and weight requirement for donors younger than 18 years old) and a blood pressure reading above 90/50 and below 180/100, explains Cedrina Calder, MD, preventative medicine doctor and health expert. Additionally, she points out that your blood count must be above a certain level and, if you are a female, you must not be pregnant. Find out why it's important for everyone to know their blood type.
There are a few, mostly minor, risks associated with donating blood
Risks associated with blood donation include bruising around the needle site, a sore arm, feeling dizzy, tired or weak, or irritation to nerves, according to Dexter Emoto, an RN at Loma Linda University Health who has personally donated 108 gallons of blood. Additionally, he points out that iron deficiency is common in donors, since every time you donate blood, the body loses a small amount of iron.
The health of the donor matters
In the months, weeks, and days leading up to your donation, it's vital that you maintain proper health, eat the right foods, stay hydrated, and get enough rest. "These steps may help you avoid being asked to wait to donate," says John Hackett Jr., PhD, divisional vice president of Applied Research and Technology for Abbott. "After you donate, eat iron-rich foods like red meat, fish, poultry, beans, spinach, iron-fortified cereals, or raisins to help your body quickly replace the blood cells that donated." Don't miss these strange facts about the human body you never knew about.
If you suffer from a chronic condition or illness, you cannot donate
If you're fighting an illness such as a fever, cough or respiratory infection, you should hold off on donating until it resolves. It's also important to note that if you have active tuberculosis, even if you are being treated for it, you cannot donate; however, Dr. Calder points out that you may donate if you have tested positive for tuberculosis with no active infection and you're not on antibiotics. "If the infection is not active, but you are on antibiotics because you tested positive, you can donate after finishing the antibiotics."
You are not eligible to donate if you have an STD
Individuals who have contracted hepatitis B, hepatitis C, chlamydia, herpes, genital warts, or HIV cannot donate blood. If you have gonorrhea or syphilis, you must wait 12 months after your treatment is completed," says Dr. Calder. In guidelines set by the FDA for all U.S. blood collection organizations, "a man who has had sex with another man during the past 12 months" is not eligible to give blood.
Giving blood is easier than you think—but come prepared
It only takes about an hour to give blood, but the process involves more than just extending your arm. "The first few minutes are for registration, including signing in with your identification and reading information about the process, and then approximately 15 to 20 minutes is spent discussing your health history, which will involve a few questions about how you feel, where you've traveled and any medications you're taking " says Dr. Hackett, Jr. "Then staff will check your temperature, pulse, blood pressure, and hemoglobin level, a protein in your body that contains iron and carries oxygen to your tissues." The actual donation itself only takes eight to ten minutes. Find out what happens to your blood after you donate it.
You're never too old to donate blood
While in most states, you must be at least 17 years old to donate blood, there is no upper age limit. In fact, as Pampee Young, MD, PhD, chief medical officer of the American Red Cross points out, many elderly individuals are some of the most dedicated blood donors. "We encourage others to join them in helping ensure blood products are available for people in need," she says. "All donors must bring a government-issued ID to show proof that they meet the minimum age requirements and for identification purposes."
You don't need to know your blood type
"According to a national survey conducted in April 2018, on behalf of the Red Cross, more than 53 percent of people believe they need to know their blood type to donate blood—this is simply not true," says Dr. Young. "We need donors of all blood types to ensure a sufficient supply for patients." If you're looking to learn your blood type from your donation, you can request to be notified following your donation when you receive your blood donor call or by creating a profile through the Red Cross Blood Donor App. These are the secrets your blood type reveals about you.
There are benefits to blood donation that go beyond saving lives
You yourself benefit when you donate: "Blood donation helps cardiac health by improving circulation. Some reports also indicate less incidence of cancer in regular blood donors," says Marisa Saint Martin, MD, assistant professor Loyola University Health System, Medical Director Pathology and Laboratory Services Gottlieb Memorial Hospital, Associate Director Blood Bank and Apheresis Services Loyola University Medical Center. "Additionally, we should not discount the mental health and spiritual benefits of being a volunteer and helping others, since volunteers in general report feeling more gratitude and joy in life."
Only 5 to 6 percent of eligible donors actually donate
Dr. Saint Martin points out, without the generosity of this small segment of the population, medicine as we know it would not be possible. "Currently, there is no viable and/or practical substitute for blood—in other words, it cannot be manufactured," she says. "Blood donors make possible many life-saving scenarios, including the survival of patients with cancer and congenital hemoglobin diseases, the support of surgeries (including gynecological), and the support of organ transplantation and trauma cases." Find out the rarest blood type in the world.
You don't have to make an appointment
All eligible individuals can make an appointment by using the free Red Cross Blood Donor App, visiting RedCrossBlood.org or calling 1-800-REDCROSS (1-800-733-2767). But even if you can't donate, you can still help the cause. "We also need organizations to host blood drives over the coming months too," says Dr. Young. "In fact, more than 80 percent of donations are made at blood drives organized by volunteer sponsor groups and coordinators—and many of these events are postponed during the holidays when regular donors tend to be busy with holiday activities and travel." To learn more about hosting a blood drive and to sign up to sponsor a drive this winter, visit RedCrossBlood.org/HostADrive.
Donating blood is about paying it forward
You might not score a tax deduction for donating blood, but donating blood is a noble act. It's truly done out of the goodness of the donor's heart. "As a nurse, I care for patients who may need a blood transfusion, and I have the opportunity to administer the blood that has been donated by a volunteer blood donor to save a life," says Dr. Emoto. "Being on both sides of the spectrum is a rare opportunity—we give to unknown recipients in need of a transfusion that may save her or his life."
