  3. Antiserum: Antiserum is produced by injecting an animal with specific antigens to stimulate the production of antibodies. It contains antibodies that can target and neutralize specific pathogens.

What is the Difference Between Serum and Plasma?

Serum and plasma are two components of blood that differ in their composition and preparation.


  • Plasma is the liquid component of blood that remains after the blood cells (red blood cells, white blood cells, and platelets) have been removed.
  • It is obtained by centrifuging whole blood with an anticoagulant to prevent blood clotting.
  • Plasma contains water, electrolytes, proteins (such as albumin, globulins, and fibrinogen), hormones, enzymes, waste products, and various other substances.
  • Plasma is used for various laboratory tests, including assessing electrolyte levels, liver and kidney function, blood clotting factors, and more.
  • Plasma is also used in the preparation of blood products like plasma-derived medications and transfusions.


  • Serum is the fluid component of blood that remains after the blood has clotted and the clot has been removed.
  • It is obtained by allowing blood to coagulate naturally or by using clotting agents, and then separating the liquid portion from the solid clot.
  • The serum is similar to plasma but lacks certain clotting factors, as they are removed during the clotting process.
  • The serum contains water, electrolytes, proteins (such as albumin and globulins), hormones, enzymes, antibodies, and other substances.
  • The serum is primarily used for diagnostic tests and screenings, such as measuring hormone levels, detecting antibodies, assessing nutritional status, and more.

In summary, the key difference between serum and plasma lies in their preparation and clotting status. Plasma is obtained by centrifuging whole blood with an anticoagulant, while serum is obtained by allowing the blood to clot and removing the solid clot. Plasma contains clotting factors, while serum lacks them. Both plasma and serum are important components of blood used for various laboratory tests and diagnostic purposes.

What is Serum Sickness?

Serum sickness is a condition that can occur as a result of an immune response to certain foreign proteins present in serum or other biologic products. It typically manifests as a delayed hypersensitivity reaction and can cause symptoms such as fever, rash, joint pain, and flu-like symptoms. Serum sickness is usually self-limiting and can be managed with appropriate medical treatment.

Unravelling an Immune Response

Serum sickness is an immune system reaction that occurs in response to the introduction of a foreign serum, typically through medical treatments or exposure to certain medications. Understanding this condition is vital for healthcare providers and patients alike, as it helps in identifying and managing adverse reactions.

Is Serum Sickness a Common Occurrence?

Serum sickness is a relatively rare condition, but it can occur in some individuals who are exposed to foreign serum proteins, such as those found in certain medications, vaccines, or animal-derived serums. It is an immune system reaction that can develop in response to the introduction of foreign proteins into the body.

The incidence of serum sickness varies depending on several factors, including the type and amount of foreign proteins introduced, individual susceptibility, and the specific circumstances of exposure. In general, the incidence of serum sickness is considered low.

Serum sickness typically manifests within 7 to 21 days after exposure to the foreign proteins. Common symptoms of serum sickness include fever, rash, joint pain, swelling, and general malaise. These symptoms are caused by the immune system's response to foreign proteins, leading to the activation of immune cells and the release of inflammatory substances.

Although serum sickness can be uncomfortable, it is usually self-limiting and resolves on its own within a few days to a few weeks. Treatment may involve supportive measures such as rest, hydration, and over-the-counter medications to relieve symptoms like fever and pain.

It's important to note that serum sickness is different from an allergic reaction, although they share some similarities. Allergic reactions involve the immune system's response to allergens, while serum sickness specifically refers to a reaction to foreign serum proteins. If you suspect you may be experiencing serum sickness or have concerns about any adverse reactions to medications or treatments, it is recommended to seek medical attention for proper evaluation and guidance.
