You don’t need to worry about losing a large amount of blood! There are different amounts to how much the blood is taken, depending on the type of blood donation.

For a whole blood donation, approximately 500 ml or one-half liter of blood is collected. For donations of other blood products, such as platelet or plasma, the amount collected depends on your height, weight, and platelet count.

How often can you donate blood?

When it comes to blood transfusion, you’d find some different kinds of blood donation. While you’re familiar with white blood cells, red blood cells, and platelets, there’s another blood component that couldn’t be less important, that is, plasma.

Plasma is the translucent component of blood that remains once all white blood cells, red blood cells, platelets, and other cellular components have been removed. We can say that plasma is a “transporting medium” that works to clot blood and fight illness within the body.

The confusion between blood and plasma can be easily understood, as plasma makes up 55% of blood. However, plasma is composed of 90% water, salt, antibodies, other proteins, and a variety of enzymes.

Donating plasma is safe for you. You can help people with severe trauma, burn or shock, cancer, and liver or clotting factor disorders by donating your plasma. If you follow normal daily nutrition and proper water intake, the body can replenish the plasma proteins and fluid that has just been donated within 24-48 hours.

This is why the FDA authorizes plasma donation up to two times within a seven day period, with at least one day interval between the first blood donation with the second one.

All of the blood components like red blood cells, white blood cells, and platelets, suspended in a plasma liquid, are called whole blood. Whole blood is the most flexible type of donation. It can be transfused in its original form, or separated into its specific components.

Then, how often can you donate blood Red Cross? According to The American Red Cross, you can donate whole red blood cells every 56 days (eight weeks), or Power Red every 112 days (16 weeks).

As a part of blood components, platelets are colorless blood cells that help blood clot. Platelets stop bleeding by clumping and forming plugs in blood vessel injuries.

You can donate platelets once in a seven day period and up to 24 times a year. You must wait at least 7 days after donating platelets before donating whole blood. After an automated double red cell collection, you must wait 112 days before donating again.

We know that white blood cells serve an important role in the immune system, helping fight infections by attacking bacteria, viruses, and germs that invade the body.

One of the important components of white blood cells is the granulocyte, donated by apheresis a maximum of 12 times in 1 year. Donations will not usually be requested more often than every 4 weeks.
