Every year, millions of individuals require blood transfusions. Blood transfusion may be required during surgery, following an injury, in severely anaemic individuals or who have dangerously low platelet counts because of certain medical conditions (bleeding disorders) and/or treatments, such as chemotherapy to treat cancer. Human blood cannot be substituted; donor blood is required for all transfusions. Blood is made up of various components, such as: • Red blood cells help transport oxygen and nutrients throughout the body. • White blood cells help combat illnesses. • Plasma is the liquid component of blood. • Platelets aid in the formation of a healthy blood clot. In this blog post, we will discuss the differences and similarities between plasma, platelets, and blood donation in detail.

Understanding about Blood, Platelets, and Plasma Donation

Blood transfusion is a lifesaving medical procedure and is single most common medical procedure carried out in the hospitals. While giving a patient a unit of blood, three components can be extracted from one unit of blood that include red blood cells, platelets, and plasma.

Let’s understand blood donation in detail:

Blood donation: It is the most common type of donation. The process of donating blood involves giving blood, which is made up of red blood cells, white blood cells, platelets, and plasma.
When you give blood, a sterile needle is used to take typically about a pint (about a half litre) from your arm. Every few months, blood donations are safe because the body replenishes the lost blood within a few weeks. Donating blood is essential for saving lives since the components of donated blood can be isolated and utilised to treat a variety of illnesses.

 

Platelet donation:  Platelet or thrombocytes are tiny blood cell fragments that aid in blood clotting. When you are hurt, they are essential in halting the bleeding. A normal platelet count is about 150,000 to 400,000 platelets per microliter (mcL) of blood. Certain medical disorders like leukaemia or adverse effects from chemotherapy might cause low platelets in certain people. When the platelet count is below threshold (often 20,000/mcL), doctors may recommend a platelet transfusion.

The procedure known as apheresis is used to separate platelets from whole blood in order to donate platelets. Blood is extracted from one arm, processed by a machine to separate the platelets, and then the donor's arm is used to receive the returned blood. Donating platelets requires more time than normal blood donation, but it's just as vital for people receiving specific medical treatments or those with clotting disorders.

Plasma donation: In plasma donation, only the liquid part of your blood is collected. Plasma can be frozen for up to a year. This liquid portion of your blood is responsible for transporting different chemicals like proteins, electrolytes, and hormones throughout the body. The proteins present in plasma help control bleeding. Hence, it's used to treat various types of bleeding disorders with clotting issues. It's also given to patients who have suffered major traumatic injuries like burns, liver and bone marrow transplants or immune deficiencies.

Similarities between Blood, Platelets, and Plasma Donation

Donations of blood, plasma, and platelets have a number of essential characteristics in common including:

• The three types of donations constitute the voluntary act of donating a portion of your blood to help those in need.
  
  
• All three types of donations are approved by the Food and Drug Administration (FDA) that oversees the process, which is safe and secures the health of both donors and receivers.
  
  
• Additionally, every contribution has the power to save lives and enhance the health of people who depend on blood products or transfusions.
  
  
• Your donation, whether it be whole blood, platelets, or plasma is essential to helping patients who are having surgery, recovering from illnesses, or dealing with life-threatening situations.

By making the decision to donate, you join a group that works to improve the health and wellbeing of the community.

What distinguishes donating platelets, plasma, and blood from each other?

While giving blood, platelets, and plasma are all vital ways to support others, there are some significant distinctions between the three. Selecting the appropriate kind of donation for you can be made easier by being aware of these distinctions. Let’s understand the differences between them:

 

In plasma donation, only the liquid portion of your blood is taken. Platelets and red blood cells are extracted and given back to you. Donating plasma is faster than donating blood; it takes roughly 1.5 hours.

Similar to plasma donation, platelet donation involves the removal of platelets rather than the collection of the liquid portion of your blood. Little cells called platelets aid in halting bleeding. Every two weeks, platelet donation can be completed in around two hours.

 

The most popular kind of donation is blood. Red blood cells, plasma, and platelets are all collected when you donate blood; the entire bag is used. You can donate blood every 56 days, which takes about 8 minutes.

The best kind of donation for you will depend on your situation. See if you are eligible to donate blood, platelets, or plasma by speaking with your doctor.

 

Thus, plasma, platelet, and blood donations all entail giving a portion of oneself to benefit others, but their functions in medical care are distinct. Every sort of play is vital to preserving lives and enhancing the well-being of people who are less fortunate. You should be aware that your donations, whether they be in the form of plasma, platelets, or blood, can have a profound impact on someone's life, so talk to your doctor to see if you are eligible.
