An autologous term has its roots in ancient Greece. There is no ambiguity in the meaning of the word “autos” (self) and “logus” (relationship). Thus,’related to oneself’ is the meaning. It is wrongly referred to as “auto transfusion” or “autologous blood transfusion” to refer to the practice of giving blood or blood components back to the same person from whom they were taken. Transfusions involving the use of blood or blood components obtained from a different human donor are known as “homologous blood” transfusions.

What does autologous mean?
Even if you search up all the meanings for “autologous” on the internet, we recommend focusing on the ones that pertain to our discussion of the benefits of autologous blood donation. In the medical field, we use the term “autologous” to refer to transplants of blood, tissues, and other organs that originate from the same person. It’s like you’re making a charitable donation for your own benefit.
What an autologous blood donation is?
You may now have a better understanding of what an autologous blood donation entails. You needn’t be concerned. Allow us to assist you in this instance. In an autologous blood donation, the recipient and donor are the same person, therefore one person donates blood for another.
So, let’s delve a little deeper into this. It can happen in a variety of ways when you claim that the donor is also the recipient of the blood. Doctors have the power to allow this to happen in a variety of conditions.
An open-heart surgery that would necessitate a large amount of blood might necessitate the doctor allowing the patient to give their own blood for the operation itself. Another scenario is when the donor has a rare blood type and no additional family members who are able to donate blood. If this happens, he will only be able to show up if he’s healthy enough and has permission from the doctor. To learn more about autologous blood donation, continue reading.
How long does autologous blood last?
To learn more about the process of blood donation, continue reading this section. An autologous blood donation is often conducted a month or weeks before where you will use it. After donating and undergoing surgery, the donor, of course, needs time to recuperate. These blood samples were only going to be around for a short period of time. That’s a 35-day estimate. At a temperature of four degrees Celsius, the shelf life of a red blood cell is approximately the same. This is a great example of an autologous blood donation, in my opinion.
Adult donors/patients are usually able to donate a considerable volume of red blood cells prior to surgery. In other words, that’s about three reticulocytes. A lot of help for sustaining blood supply during surgery. Wherever they couldn’t verify that all other donors’ blood was safe for the patient, this is frequently done. Therefore, for the sake of the patient’s safety and, obviously, a better likelihood at a successful surgery, they choose autologous blood transfusion. You can find it right here. Transfusion of the patient’s own red blood cells (autologous blood transfusion)
What Is The Difference Between Autologous And Allogeneic Blood Transfusion
A non-related/anonymous donor provides an allogenic blood transfusion. It is the most common form of blood transfusion at blood donation sites. Allogeneic blood transfusions occur when a donor gives blood to a stranger who has no connection to the donor. An infection can still be transmitted even when the blood has been thoroughly tested to guarantee that it will not harm the patient in any manner whatsoever.
Step 1: Ask your doctor
Ask your doctor if you can donate blood in advance of a surgery if you’d like to do so. Whether you’re healthy enough to donate blood and whether your procedure requires blood transfusions can be determined by your doctor.
First-time donors who are considered “High Risk” will be screened by the Blood Bank Physician prior to donating. Heart patients, people with infections or seizure problems, pregnant women and toddlers are all considered “high-risk” donors (children must be at least ten years old, and weigh at least 65 pounds).
Step 2: Prepare for your donation
Your body and blood should be in the best shape possible. Red blood cell production necessitates the presence of iron. It’s a good idea to donate blood in order to remove iron from your system. Anemia can result from an iron deficiency. An iron-rich, vitamin C-rich diet may help your iron levels if you follow a well-balanced eating plan. In addition, an iron supplement is recommended. 65 mg of elemental iron is the recommended daily dose for iron supplements. Ferrous sulfate, a 325 mg iron supplement, can be gotten by mixing it with orange juice or a meal and taking it once every other day. As soon as possible after scheduling your appointment, begin taking the iron and continue for four months after surgery. It’s a good idea to check with your doctor or surgeon to see how long you’ll need the supplement after surgery.
Step 3: Schedule your appointment
Your surgeon will need to fill out an autologous blood donation request form once you and your doctor have agreed on a surgical date. Prescriptions for this medication must include the following information from your physician:
- Legally, you are known as “
- Your birth date
- Your operation’s start date
- How many blood units will you require?
You can make an appointment with the Blood Bank secretary after your doctor has mailed or faxed the request form to the Donor Program. Depending on how much blood you need to donate, you may have to make more than one appointment. You must have at least three days between your appointments. Donations of autologous blood must be completed at least three days ahead of time in order to avoid any complications during operation. Donations should be scheduled at least seven days apart and at least seven days prior to surgery to avoid complications. Plan your appointments ahead of time in case you are sick, have low blood counts, or experience difficulties getting your blood drawn and must reschedule.
In addition, it is advisable to have a friend or family member drive you to and from your appointments.

Step 4: Make your donation
Do not skip meals the day of your consultation. Be sure to stay hydrated by drinking a lot of water.
Seven to ten minutes is all that is needed for the treatment, which is carried out by a qualified and certified technician. The needle may sting a little bit, but the donation itself should be painless. The needle used for your contribution is new, disposable, and used only once for your donation’s purposes.
Depending on your weight, each donation requires about a pint of whole blood. The average adult has eight to twelve pints of blood in reserve and is more than willing to donate one of those. After the donation, you’ll get some time to relax and enjoy some refreshments. Your appointment should last about an hour.

What Are The Methods Of Autologous Blood Transfusion
Autologous blood transfusions can be performed in a variety of ways. As long as the doctor thought it was appropriate, methods were based on what the patient agreed to. These are the various approaches.
#1. Predeposit autologous transfusion
About three to five weeks before to the procedure, blood samples are taken for testing. The total amount collected will be between 1-2 liters, depending on the number of units taken throughout this period.

Before the procedure can begin, blood must be collected in the operating room, specifically in the anesthetic region. This is primarily used for patients who have been predicted to have lost between 1 and 1.5 liters of blood.

During the procedure, this method of autologous blood transfusion is used.
