Blood Plasma

Blood plasma is a frequently overlooked component. The function of the body depends on platelets, red blood cells, and white blood cells. But plasma also has a significant impact. The blood components are transported throughout the body by this fluid.

Blood Plasma

The liquid portion of the blood is called blood plasma. Blood has different components like platelets, erythrocytes, leukocytes, and other blood cells. A normal human body has approximately 5 to 6 quarts or 5 liters of blood.

Facts About Plasma

The majority of your blood is plasma. The component of blood which occupies more than half of the blood is plasma. Blood contains 55% plasma. Plasma is a pale yellow liquid that forms when the blood is separated from the rest of it. Plasma functions in carrying different molecules throughout the blood to different parts of the body. Molecules carried by plasma are different salts, water, and certain enzymes.

Blood Plasma

The main function of plasma is to transport important molecules in the body, like hormones, nutrients, and proteins. Additionally, plasma is where cells dump their waste. The plasma then aids in the body's elimination of this waste. Even the components of the blood, like RBC, WBC, and other proteins, are transported through plasma in the circulatory system.

Role Of Plasma in The Health of The Body

Many health issues require blood plasma as a vital component of treatment. For this reason, people are asked to donate blood plasma at blood donation drives.

Plasma also has vital components, such as water, salt, and enzymes. These contain clotting elements, albumin, fibrinogen, and antibodies. Healthcare professionals can extract these essential components from your plasma when you give blood. Then, these components can be condensed into a variety of goods. Then, these items are employed as remedies to help those experiencing burns, shock, trauma, and other medical situations save their lives.

The proteins and antibodies present in the plasma are used to treat various uncommon, chronic diseases. These include hemophilia and autoimmune diseases. Because of the treatments, people with these diseases can lead full and active lives. Because of all the help in treatments that have come from plasma, it is referred to as the "gift of life" by many medical institutions.

Donating Plasma

You must go through a screening procedure if you wish to give plasma to those in need. This is done to guarantee the safety and health of your blood. Every subsequent appointment at the clinic will take roughly an hour and a half if you are eligible to donate plasma.

Blood Plasma

Your blood is taken during the actual blood donation procedure using a needle inserted into a vein in one of your arms. Your blood sample is processed using a specialized machine that separates the platelets and plasma. Plasmapheresis is the name of this procedure. A small amount of salt is added afterward in the form of salt solution to the remaining RBCs, and then they are returned to the body.

Most plasma donors are of blood type AB, which is in high demand. Their plasma is ubiquitous and only makes up 2 in every 50 persons. This implies that anyone can use their plasma.

Every 28 days, up to 13 times a year, anyone can donate plasma at non-profit donation centers.

Who Should Donate Plasma?

The Red Cross urges people with blood type AB to think about donating plasma. Patients with any blood type can receive AB, the only universal plasma. As a result, type AB plasma transfusions can be administered right away without wasting valuable time checking the patient's blood type compatibility. Saving time is crucial in emergency medicine, especially when treating patients who have suffered severe burns or substantial trauma.

Functions of Plasma

Your body's plasma can serve several functions:

  • Transport water throughout the body
  • Transport proteins and antibodies to those parts of the body where they are required.
  • Carry various hormones, nutrients, and other macromolecules to be transported to different organs.
  • Keep the blood vessels intact by preventing their collapse.
  • Helps in the exchange of gases in the blood
  • Maintain blood pressure in the body
  • Balance the heat in the blood and provide thermal regulation.
  • Prevent blood clotting by transporting water from cells to different organs.
  • Helps in transporting the waste of the blood to various organs of the body, such as kidneys, for elimination.
  • Protect the blood from catching unwanted microorganisms and infections.

Donating Plasma

There are two methods for giving plasma:

When giving whole blood, a medical professional inserts a needle into an arm vein and pulls blood. Plasma will then be separated in a lab as necessary.

Blood Plasma

When donating plasma alone (plasmapheresis), a medical professional will insert a needle into a vein in your arm to take blood, much like when you have entire blood removed. A centrifuge spins the blood as it enters it, separating the plasma from the blood cells and platelets. After removing the separated plasma, the apparatus returns the remaining blood components to your body as saltwater (saline) solution.

Within 24 hours of taking plasma from your body, the lab freezes the donated plasma to protect the immunoglobulins and clotting factors. A year is the shelf life of frozen plasma.

Although plasma from donors with blood type AB is preferred since it does not contain antibodies and can be administered to people of any blood type, anyone can contribute.

Where is Plasma Developed?

Your umbilical cord cells make plasma cells in the embryo. Plasma proteins are created after development in your spleen, liver, blood cells toward the end of their life, and the soft tissue of your bones (bone marrow).

What Does Plasma Look Like?

A liquid is plasma. It has a straw-like appearance and a pale-yellow tint. Although plasma accounts for more than half of the overall volume of your blood, the color of your whole blood is mostly determined by red blood cells.

Percentage Of Blood Plasma

55% of the blood comprises plasma. White blood cells and platelets make up the next 44% of your blood's volume, leaving just 1% for red blood cells.

How Can Plasma Be Distinguished from Other Blood Constituents?

Your blood sample is separated into multiple layers while it spins in a centrifuge machine (centrifugation). Your blood cells (red and white) and platelets are found in the bottom layer of the yellow top layer of plasma.

Components of Blood Plasma

Blood plasma is made up of the following:

  • Water.
  • Proteins (albumin, fibrinogen, globulin) (albumin fibrinogen, globulin).
  • Liquefied minerals and salts with an electric charge (electrolytes).
  • Antibodies

Proteins In Plasma

Several proteins can be found in plasma, including:

  • Albumin: Transports hormones, vitamins, and enzymes throughout your body and helps keep fluid in blood vessels confined, so it doesn't seep into tissues.
  • Immunoglobulins, also known as antibodies, protect your body from pathogens like bacteria, fungi, viruses, and cancer cells.
  • Fibrinogen and the von Willebrand factor are clotting factors: that reduce bleeding.

Communicable Infections Through Plasma

Your healthcare practitioner will test your blood for communicable infections following removal to guarantee the security of your blood sample. Your healthcare practitioner will also test your plasma at the same procedure for the same disorders, like HIV, syphilis, or Hepatitis A, B, and C.

Diseases or Health Conditions Impacting Blood Plasma

Blood plasma can be impacted by a number of uncommon disorders, including:

  • A protein condition known as amyloid light-chain amyloidosis causes plasma cell antibody proteins to alter in form and bind collectively to deposit in organs, impairing organ function.
  • Blood disorders like haemophilia and von Willebrand disease make it difficult for the blood to clot, making even minor wounds capable of causing life-threatening hemorrhage.
  • Immunodeficiency: A condition in which your body lacks enough antibodies to defend itself against infection (immunoglobulins).
  • Blood clots in small blood arteries are a symptom of the blood condition thrombotic thrombocytopenic purpura.

Plasma Abnormalities

The following are signs of plasma conditions:

  • A bone ache.
  • Easily bleeding or bruising.
  • Heart flutters (arrhythmia).
  • Having wrist and hand pain (carpal tunnel syndrome).
  • compromised immune system

What Procedures Evaluate the State Plasma in the Body?

To determine the state of the plasma, there are numerous tests available:

  • Your healthcare professional performs a bone marrow biopsy to check for abnormal plasma cells.
  • An examination of your complete blood count might reveal details about your blood and general health.
  • The plasma protein test determines the quantity of all plasma proteins in your blood.

Maintaining Healthy Plasma

Maintaining plasma health involves:

  • Keeping hydrated by consuming lots of water.
  • Consuming a balanced diet.
  • Doing regular exercise.
  • By maintaining adequate hygiene, infections can be avoided.
  • Vitamin intake to strengthen the immune system.


Plasma is the fluid that binds your red, white, and platelet blood cells together and is necessary for your body to function. Your plasma donation helps others lead healthy lives despite the rarity of plasma diseases.
