Overview
Blood donation is a tried-and-true method of saving lives. Donations of blood and organs, as already said, are crucial to the survival of many people.
More than a thousand patients a year are cared for by the medical staff at Yale Medicine’s Transfusion Medicine Service. Yale Medicine regularly participates in clinical trials to investigate cutting-edge therapeutic apheresis applications.
How does apheresis work?
Traditional blood donation consists of four components: whole blood, red blood cells, white blood cells, platelets, and plasma. In the event of a medical emergency, such as following surgery, an accident, an illness, or chemotherapy, components are stored and given to patients as needed.
Apheresis separates the blood into various components while the donor is still linked to the separation equipment. Complete blood from a donor is separated into its component parts using density and a centrifuge or a moving belt.
Red cells are the densest, thus they sink to the bottom,” explains Edward Snyder, director of the Transfusion Service. Next in density after red blood cells are white blood cells, then platelets, then plasma.
The apheresis professional collects the unneeded blood components by putting a tiny needle into a vein in the arm and withdrawing the blood. Some people have their blood collected and returned through a central line (a catheter inserted into a vein in the upper shoulder).
What is donor apheresis?
Apheresis is a method whereby healthy donors’ blood is separated into its various components (RBCs, WBCs, platelets, and plasma) and then returned to the donor. Hospitals may choose to hold on to the component in order to provide it to those who require it. Apheresis samples are collected at donation centers and at mobile blood drives like those arranged by the American Red Cross in Connecticut.
Whole blood donation is more time-consuming than donor apheresis, but it has fewer risks to the donor and more benefits for the recipient.
Machine apheresis can be used to separate RBCs from plasma and platelets, with the latter being returned to the donor along with the former. Donation centers can obtain twice as many RBCs from this procedure as they would from a whole-blood donation. Platelet apheresis enables the administration of as many platelets as may be collected from four to six whole blood donors.
Frozen or processed apheresis plasma can be made into pharmaceuticals like gamma globulin by treating and processing donated plasma. The maximum time between double apheresis red cell donations and platelet donations is 16 weeks, but donors can provide platelets as often as once every seven days.
The Process Of Apheresis Blood Donation
Donated plasma can be processed and transformed into medications like gamma globulin through apheresis plasma freezing and processing. Donors can provide platelets as often as once every seven days, but up to 16 weeks must pass between double apheresis red cell donations and platelet donations.
Simply put, apheresis blood donation involves giving blood without actually drawing any. Apheresis platelets provide a far larger increase in platelets in the recipient’s body than would be the case with six blood transfusions. Donating blood via apheresis helps patients keep their immune systems healthy. Donating blood via apheresis is beneficial for those who are battling cancer, leukemia, or have undergone a bone marrow transplant.
Platelets
Platelets are a cellular component of the blood. Most of the blood is made up of platelets, plasma, red cells, and white blood cells. Platelets are a type of blood cell that helps to stop bleeding. That’s just throwing money away. Humans can survive on platelets alone. Those who have undergone cardiac surgery, those who have battled cancer, those who have received organ or bone marrow transplants, those who have experienced catastrophic injuries, and many others all have a vested interest in living as long and as healthy a life as possible.
How Much Time It Takes For The Process Of Apheresis?
Time required for an apheresis blood donation is largely dependent on the donor’s physical characteristics. Apheresis typically takes between 70 minutes to two hours, according to the doctors and other specialists undertaking the research. Apheresis blood donation requires meticulous planning and execution. Is it clear to you what to do? Continue reading if you haven’t already; apheresis consists of the following procedures:
- The act of signing up to become a donor.
- Having a Chat About Donor Health
- Nutritionally, juices are a solid choice.
- Try to incorporate a wide range of nutritious produce into your diet.
Apheresis donors are encouraged to take their time and unwind by watching TV, listening to music, or enjoying a movie.
What Are The Benefits Of Apheresis Versus A Whole Blood Donation?
Consider the distinctions between apheresis and a conventional blood transfusion. Here are the specifics:
Whole blood donation
Whole-blood (WB) donations are also accepted; in this case, a person gives one unit of their entire blood supply rather than only a portion of it.
Apheresis blood collection
Do you have questions about giving blood using apheresis? I hope that this helps to clarify the situation for you. Let’s examine it more closely. Apheresis blood collection involves the voluntary donation of blood. In this method, donors typically give more blood than during a standard blood drive. Apheresis contributions have the potential to save many more lives than conventional blood donations. Life expectancy is greater for apheresis blood donors than it is for whole blood donors.
Benefits Of Apheresis Blood Donation
Do you want to learn more about giving blood using apheresis? Below you can find the reply to your question. Let’s continue the discussion. Apheresis is a technique used to collect blood for transfusion. It is more common for a donor to give more blood in this way than to give whole blood or normal blood. Thousands more lives can be saved with apheresis donation than through routine blood donations. In apheresis blood donation, the life expectancy of recipients is longer than in whole blood donation.
Consider reading up on the adverse effects of giving plasma.
What is therapeutic apheresis?
Think about learning more about the risks associated with plasma donation.
In cases where there are an excessive amount of white blood cells or platelets, a leukapheresis or plateletapheresis may be necessary.
Dr. Snyder says it is conceivable to transplant healthy red blood cells into a patient to replace the ones that the patient’s body has destroyed.
What are some of the conditions that may be treated with apheresis?
Characterized by the presence of the sickle cell trait. This genetic disorder causes abnormal red blood cells (formed like sickles) that are unable to carry oxygen effectively. Sickled red blood cells can be removed and replaced with healthy ones from a blood donor via a procedure called erythrocytapheresis in the case of a sickle cell crisis.
Leukemia. Having too many white blood cells can cause the blood to thicken and affect organ function in patients with leukemia. Blood that has aberrant white blood cells removed is returned to the patient during leukapheresis.
This condition is known as purpura thrombocytopenicum thrombocytopenia (TTP). This rare blood disorder manifests as systemic platelet aggregation; its etiology is the deficiency of a key blood enzyme. The best treatment is a combination of plasmapheresis and the administration of normal donor plasma, which already contains the enzyme necessary for recovery.
How is apheresis used for stem cell transplants?
Stem cells in the bone marrow can differentiate into a variety of blood cell types. Apheresis is a procedure in which a patient’s stem cells are harvested from their blood and then returned to them after the patient has been treated for a blood cancer such as leukemia, multiple myeloma, or lymphoma.

Before leukapheresis, a patient takes a growth factor drug to increase the number of stem cells that will be extracted from the patient’s blood and returned to them after the procedure. They are stored in the freezer until the end of the patient’s radiation or chemotherapy treatment.
Whenever we reintroduce the stem cells,” Dr. Snyder says. When transplanted into a patient, stem cells have the potential to divide and replenish the recipient’s bone marrow. Most of these cells can, thankfully, regenerate.
It’s been a while since we last did this treatment in conjunction with medical oncology, and it’s time. It is currently standard practice for treating several forms of blood malignancy.
What can a patient expect when undergoing apheresis?
Depending on the severity of the patient’s illness and the complexity of the component to be gathered, the procedure might take anywhere from two to four hours. Side effects of apheresis include pain in the arm where the needle was inserted, dizziness, sweating, or a rise in blood pressure, however the procedure itself is usually uneventful.
Dr. Snyder of the Cleveland Clinic suggests that these complications may be more common with apheresis because it takes longer and requires two needles in each arm. However, he claims that the vast majority of apheresis patients do not suffer any adverse effects.
Donor components, such as red blood cells, have the risk of triggering an allergic reaction or fever in the recipient; however, Dr. Snyder emphasizes that patients are continuously monitored, so any adverse effects are quickly identified and remedied.
Treatment can be repeated as often as once per week, once per month, or even more frequently than that. In most cases, apheresis therapy is performed in conjunction with preexisting treatments like steroid medication or chemotherapy.
What makes Yale Medicine’s approach to apheresis unique?
Dr. Snyder claims that, as a large research facility, Yale Medicine follows all applicable medical safety regulations and has a permanent staff of Blood Bank physicians to handle any emergencies that may arise. To better treat patients suffering from a wide variety of conditions, we strive to keep our apheresis equipment at the forefront of therapeutic apheresis research.
Apheresis sessions at Yale Medicine are scheduled throughout the day, although the clinic is open 24/7 in case of an emergency.
“Our staff is committed to assuring patient safety, patient comfort and proper medical care,” adds Dr. Snyder. When you need us, we’ll be right here for you.
Requirements Of Apheresis Donation
“Our staff is committed to ensuring patient safety, patient comfort, and proper medical treatment,” Dr. Snyder continues. We are here to assist you at any time.
- The minimum weight for a donor is 115 pounds.
- The 16-year-old has his parents’ OK to start donating blood.
- Donation is only possible if the donor is in good health.
- If the donor meets all other requirements for apheresis blood donation, their platelets will be counted before the donation.
- If you meet the requirements to give blood, you must wait 36 hours after giving blood before taking any aspirin.
Is apheresis a risky procedure? Yes. As a result of this procedure, the donor and the recipient are both safe. A team of trained professionals oversees each apheresis donation to ensure the safety of the donor and the recipient. There is no danger of excessive bleeding because only a small number of platelets are counted. Donated platelets are replaced by freshly generated ones within 48 hours. Apheresis calls for the following supplies:
- Smaller-sized needles
- Tubes
- Polyethylene terephthalate bags
Be cognizant of the fact that donated secondhand equipment is unavailable. What are the benefits of giving blood? Read this article to discover further information.
What is apheresis blood collection?
The donation of blood through apheresis is called ABC. In place of one pint of whole blood, ABC donors just donate the blood components that are needed for that day’s patients. Using only a single needle, a remarkable machine separates the constituent parts of your blood, keeps some of them, and then returns the rest to you. Because it’s so effective, it’s an excellent method for immediately aiding hospitalized patients. We can support the community by donating the right amount of blood components at each donation, which will help keep these life-saving items readily available.
What are the requirements for apheresis blood collection?
Apheresis-based blood donation (ABC) refers to the process of donating blood using a machine. Donors who participate in the ABC system only give the specific blood components that are in demand on any given day, rather than a full pint of blood. With just one prick of a needle, an amazing machine can extract your blood’s useful components, store them safely, and return the rest of your blood to you. It’s a great way to help patients in hospitals right away, and it works quite well. Donating the appropriate volume of blood and other blood products at each donation will help ensure that these essential supplies are always available in the community.
Why are the requirements different for women, men and nonbinary donors?
Because men and women have different total blood volumes even when they weigh the same (TBV). Standard practice dictates that no more than 15% of a patient’s TBV should be drained at any one time. In order to determine TBV, the apheresis machines we utilize take into account the patient’s gender, height, weight, and hemoglobin levels.
It’s A Wrap!
Thank you so much for reading to the conclusion, my dear friends. We just had to let everyone know about blood donation using apheresis. If I wanted to know why I was turned down to donate blood and how organ donation helps save lives, I might look into it.
