Can you freeze blood?

In this article, we will answer the question “Can you freeze blood?” and discuss how to store blood?

Can you freeze blood?

Yes, you can freeze blood. If we don’t freeze it, blood may be stored for 42 days. Although blood that has been frozen may be kept for up to 10 years, this is a poor method of preserving blood. In general, blood is kept in the refrigerator, where it may be kept for up to 42 days without losing any of its quality.

Get to Know Every Step of the Blood Transfusion Process

As a result of the donation

  • Blood donations are scheduled for your arrival at the clinic.
  • It’s time for health history and a short physical.
  • In order to donate a full pint of blood, many tiny test tubes of blood are also taken for testing purposes.
  • The bar codes on your donation, test tubes, and donor record are all the same.
  • A Red Cross facility will process your gift and transport the test tubes to the lab.


  • Your contribution information is entered into a computer database at our processing center.
  • Most whole blood donations are centrifuged to separate red cells, platelets, and plasma into transfusable components.
  • Cryoprecipitate, a component of plasma that helps blood clot, may be used to reduce the chance of blood clots breaking open.
  • Leuko-reduction is the process of removing your white blood cells from your red and platelet transfusions in order to lessen the risk of the receiver developing an allergic response to the transfusion.
  • When administering a transfusion to a patient, physicians will utilize a defined quantity of each component packed as a “unit.”


  • Your test tubes arrive at the testing facility at the same time.
  • A dozen blood and infectious disease tests are carried out to determine the patient’s blood type and to screen for illness.
  • Within 24 hours after receiving the test results, they are electronically sent to the processing facility.
  • If a positive test result is found, your gift will be thrown out and you will be informed (our test results are confidential and are only shared with the donor, except as may be required by law).


  • Units appropriate for transfusion are tagged and kept when test results are obtained.
  • Red blood cells may be preserved at a temperature of 6oC for up to 42 days in a refrigerator.
  • For up to five days, platelets may be kept in agitators at room temperature.
  • It may be held for up to a year in a freezer for cryo and plasma storage.


  • Hospitals may order blood 24 hours a day, seven days a week.
  • Although most hospitals maintain some blood units on hand in case of an emergency, they may need to order more at any moment.


  • Hospitals and other treatment facilities receive patients who are sick or wounded and need care.
  • Medics decide whether or not a patient needs a blood transfusion.
  • Patients are given blood transfusions in a variety of situations, including major injuries, operations, childbirth, anemia, blood diseases, cancer therapies, and many more. See the Benefits of Blood Donation.
  • Red blood cells may be given to patients with an iron shortage or anemia in order to boost their hemoglobin and iron levels, hence increasing the quantity of oxygen in the body.
  • Platelet transfusions may help patients who are unable to produce enough of their own platelets owing to sickness or chemotherapy.
  • Those in need of plasma transfusions include those with liver disease, life-threatening infections, and severe burns.

Blood transfusions may now be stored in a revolutionary new method.

Unfortunately, the supply of blood is limited since it cannot be stored for extended periods of time due to the fluctuating volume of blood given. It’s possible that the UK has little more than five days’ worth of supplies of certain rarer blood types.

Adhesive for wood

Thawing blood crystals forcefully rip blood cells apart, resulting in pink mush that can’t be used. According to University of Warwick scientists, a solution to this difficulty has now been identified, allowing donors to freeze their blood in significant quantities for the first time.

After three years of research into how blood freezes and thaws, scientists headed by Dr. Matthew Gibson discovered that adding a specific polymer to blood before freezing might alter the behavior of ice crystals.

A large amount of stock

The addition of a polymer is completely safe and does not need to be removed before a blood transfusion since it is used in such tiny quantities. It’s feasible that large-scale trials of this notion might begin within the next 12 to 18 months, according to Dr. Gibson and his colleague Robert Deller, if the NHS shows interest.

People with really uncommon blood groupings might find it quite helpful at first. They might save their own blood in anticipation of a time when they might be in need of it by donating and freezing it. Bone marrow freezing might benefit from this strategy, as could the freezing of platelets and perhaps stem cells.
