I started donating blood a few years ago after being encouraged by my daughter to attend a blood drive sponsored by her employer. While at the blood drive, I had a nice conversation with the phlebotomist about the ins and outs of blood donation and I found it fascinating. For starters – there was and is a massive blood shortage. Cold winters are to blame, as those who sign up to donate blood don’t make their appointments due to inclement weather.
So far in 2018, more than 5,500 blood and platelet donations have gone uncollected and more than 150 blood drives were forced to cancel due to the early January winter storm along the eastern seaboard. Another reason for the shortage is increased demand, due to the increased number of complex therapies such as chemotherapy, organ transplants and heart surgeries.
Even temporary disruptions to blood and platelet donations can diminish the availability for hospital patients, Clifford Numark, senior vice president of Red Cross Blood Services, said in a statement. It’s the blood on the shelves that helps save lives in an emergency.
Humans cannot live without blood, and there is no replacement or substitute for blood. Blood performs many jobs for our bodies and is continuously working around the clock. What is this mystery substance and what is its makeup?
Whole blood makes up about 7% of a person’s body weight and consists primarily of red blood cells, white blood cells, platelets and plasma. Red blood cells, created in the bone marrow, are constantly being replaced. White blood cells fight off infection. Platelets coagulate blood and help it clot. Plasma keeps the various other cells fluid and moving through the veins and arteries. Not only can you donate blood, but you can donate platelets and plasma.
What is your blood type that is unique to you? There are four types:
- Type A – Red blood cells with only “A” molecules on it.
- Type B – Red blood cells with only “B” molecules on it.
- Type AB – Red blood cells that have a mixture of both “A” & “B” molecules
- Type O – Red blood cells that have neither “A” or “B” molecule.
O positive is the most common blood type, representing 37 percent of the U.S. population. B and AB are less common, with O negative being very rare – representing less than 5% of the world’s population. The red cross loves me as my blood type is O negative which means I am a universal red cell donor. Blood type A, B, and AB can only be donated to those who match their type. Type O-negative blood is universal and therefore is compatible with any blood type. Some people with rare blood types such as O-negative bank their own blood in advance of surgical procedures to ensure that blood is available to them.
Blood is also classified by rhesus (Rh) factor, which refers to a specific red blood cell antigen in the blood. If your blood has the antigen, you’re Rh positive. If your blood lacks the antigen, you’re Rh negative.
Donating blood is critical. Your contribution is important for a healthy and reliable blood supply and it makes you feel good knowing you will help change a life. On the day of your donation, you will be given a set of questions to answer regarding your medical history and your hemoglobin levels will be tested. Hemoglobin is a protein in your body that contains iron and gives blood its red color. Hemoglobin is responsible for carrying oxygen from your lungs to nourish all of the tissues in your body. Women must have a minimum hemoglobin level of 12.5g and males must have a minimum level of 13.0g. Women must also be over 110 pounds to give blood. I hover right at 110, so I am only able to donate 1 pint of blood as opposed to 1 quart.
You can check the Red Cross Eligibility Requirements before your first visit.
You will get an email after you have donated blood telling you that your blood is on the way to the hospital, and how many lives you are saving. This is a powerful email to receive. You will be given a donor card, where you can logon to the LifeSource website and view your wellness profile after your donation. Your pulse, blood pressure, body temperature and hemoglobin can be viewed, as well as your cholesterol levels.
If you struggle with how to give back and save a life in the process – I cannot think of a simpler thing to do than to donate blood. It takes about 45 minutes out of your day every 3 months or so, you receive a sticker, save a life, and have some apple juice and cookies when you are finished – what could be more simple?
