There are different types of blood donation: While the other methods of donation only use a portion of your blood, whole blood donation uses all of it. A "blood product" is what we refer to as donated blood. Each type of blood product is required and has a finite shelf life. This is why it is crucial to donate blood multiple times a year, or even more frequently if you can.

The removal of a particular blood component, such as platelets, red blood cells, or plasma, is known as apheresis. You donate blood through a needle and tube during this procedure, just like you would normally. However, in contrast to donating blood normally, the tube is attached to a sophisticated device that separates out a specific component of your blood before returning the blood and residual blood components back into your body through the same tube. A donation by apheresis takes longer than a donation of whole blood. Depending on the blood component to be donated, an apheresis donation can take between one to two hours, while it takes about 20 minutes for whole blood.


 A brief explanation of each type of blood donation is listed below.



Whole blood donation is an all-round type of donation. The average donation of whole blood is one pint. Your blood is divided into its constituent red blood cells, platelets, and plasma following donation for distribution to other hospitals.



Platelets are essential for clotting and may be required by cancer patients, accident victims, and other patients with blood clotting issues. A concentrated volume of platelets can be collected using automated equipment during a platelet donation.



Plasma is a concentrated liquid that may be collected using automated technologies and used to treat burn and accident victims. Plasma helps the circulatory system carry nutrients and proteins in the blood throughout the body. Donors of type AB are particularly valuable as plasma donors.



Two units of concentrated red blood cells are gathered. The amount of life-saving red blood cells you can donate in this way is twice what you can donate in a complete blood donation. Red blood cells are separated from the blood by a machine which then gives platelets and plasma back to your body.
