    Why Are Blood Donors Important?

    Blood and bone marrow donors are an important part of the research process

    Researchers worldwide are developing new treatments and cures for significant medical conditions including cancers, rare childhood diseases, and autoimmune disorders. To do this important work, scientists need human cells during the research and development process to fully understand how their treatments and cures will respond in the human body. Blood and bone marrow donations from people like you can provide researchers with the cells they need to ensure their treatments are safe and that they really work

    Types of Donations

    Scientists utilize unique components of human blood and bone marrow, in an effort to find treatments and cures for a multitude of medical conditions. Here at StemExpress, we streamline this process to provide these researchers with the exact samples they need. Take a moment to read about the ways you can donate and what’s involved.

    White Blood Cell Donation (Apheresis)

    White blood cells are one of the four components of whole blood. A white blood cell collection procedure is called apheresis (ay-fer-ee-sis). Apheresis is the process of drawing blood, filtering out parts of the blood through a cell-separating machine, and then returning the blood back to the donor. The process takes up to 4 hours and donors are able to resume their regular activities after donating! Apheresis collections can be used for research and development and in some cases is used to treat blood cancers through allogeneic and autologous treatments.

    How it works: In order to qualify for apheresis, you must have large veins in both arms. You will be seated in a chair in a comfortable position and a sterile needle will be inserted into each arm. Your blood will be drawn from one arm and pass through the apheresis machine. The machine will separate the white blood cells and plasma and collect them in a bag.

    The remaining components of your blood will be delivered back to you in your other arm. Please be aware that since the needles remain in your arm for the entire procedure, you cannot bend your arms for the length of the donation. If you need assistance (or even need your nose scratched!) you can always ask a StemExpress staff member. We are here to help! You will have a TV with wireless headphones and cable or Netflix to pass the time.

    Time: A white blood cell collection takes between 4 to 5 hours. Please be aware that if the procedure is interrupted, you cannot be reconnected to the machine, and you may not be eligible for the entire amount of the compensation. Gaps between white blood draws must be at least 4 weeks.

    Compensation: You will be compensated $150 for your apheresis (white blood cell) appointment.

    Whole Blood Donation

    Whole blood donations are the most common type of blood donation. During a whole blood donation, the blood with all of its parts is drawn from a vein in the donor's arm. Whole blood donations only take about 30-45 minutes in total. This short amount of time makes a huge difference to scientists around the world who need whole blood for their important research.

    How it works: A whole blood donation is a simple blood draw. A phlebotomist will insert a sterile needle into your arm and collect the blood in a blood bag or in tubes.

    Time: A large blood draw (between 200 and 500 ml) will take about 10-15 minutes. Plan to spend 30-45 minutes in the collection center.

    A small blood draw (under 200 ml) will take about 5-10 minutes. Plan to spend 20-30 minutes in the collection center.

    Compensation: You will be compensated $50 for a small blood draw appointment and $100 for a large draw appointment.

    Bone Marrow Donation

    Whole blood donations are the most common type of blood donation. During a whole blood donation, the blood with all of its parts is drawn from a vein in the donor's arm. Whole blood donations only take about 30-45 minutes in total. This short amount of time makes a huge difference to scientists around the world who need whole blood for their important research.

    How it works: Bone marrow donations may seem a bit scary, but they are actually relatively quick and generally very tolerable. A licensed healthcare provider will perform the procedure. You will lie on your stomach on the exam room table and a local anesthetic will be applied to numb the donation area. The bone marrow will be extracted from your iliac crest (hip) on either side. During the withdrawal of the bone marrow (called aspiration), you may feel a brief pinching sensation. When the draw is complete, you should not experience any impairment to your normal functioning, and should be safe to drive home.

    Time: The Bone Marrow appointment takes 25-30 minutes. Plan to spend 1-2 hours in the collection center.

    Compensation: You will be compensated $250 for your Bone Marrow appointment.

    Mobilized Blood Donation

    Mobilized blood donations are very important to researchers! Donors who qualify for a mobilized blood donation are injected with a "mobilizing agent" a few days before their donation to SUPERCHARGE their immune cells! These cells are then collected and used by scientists worldwide searching for treatments and cures for some of the most challenging diseases.

    How it works: A mobilized white blood cell collection is a special kind of white blood cell appointment where you will receive injections of a “mobilizing agent,” (G-CSF, a drug which boosts your body’s white blood cell production) before your apheresis appointment. If you qualify for this procedure, you will be scheduled for up to five days of G-CSF injections prior to your apheresis appointment.

    Time: The first G-CSF appointment will take about an hour. The following G-CSF appointments will take approximately 30 minutes.

    The white blood cell collection appointment will take between 3 to 4 hours (the same as a regular white blood cell collection).

    Compensation: Depending on the project you qualify for and your total number of G-CSF injections, you are eligible for up to $1000.

    *Qualified donors are eligible to be mobilized by G-CSF twice in a lifetime. You are able to continue other donations regularly, such as small and large blood draws, after the specified deferral period.

    Becoming a blood or bone marrow donor has a BIG impact on important research around the world. Understanding the role individual cells play in the human body can help you understand why scientists need them.

    White Blood Cells

    White Blood Cells Basophil

    Basophils

    Basophils are a type of powerful little immune response cells known as granulocytes. Basophils are responsible for your body's immune response, recognizing foreign invaders in the body and attacking them! Basophils are incredibly important for keeping you healthy and strong, defending the body against allergens, viruses, bacteria, and parasites! Basophils even prevent dangerous blood clotting! Overactive basophils are responsible for asthma - so if you or someone you know suffers from asthma, you now know it's their basophils working overtime.

    Eosinophils

    Eosinophils are another important immune response granulocyte. Eosinophils play a large role in keeping you healthy by defending the body against allergens, pathogens, and parasites! Have allergies? You can thank basophils AND EOSINOPHILS for that! So the next time you have itchy eyes on a beautiful spring day, you can lovingly tell your eosinophils "chill out!"

    White Blood Cells Eosinophil
    White Blood Cells Neutrophil

    Neutrophils

    Neutrophils are another immune response granulocyte. Neutrophils are the body's emergency response system when bacteria invade. They are sort of like your body's very own first responders! If you have an infection or a tissue injury, you can count on neutrophils to show up and fight off bacteria... gobbling them up like Pac Man!
