What is Plasma Therapy?

Plasma therapy is the process of administering plasma or plasma-based products to increase the levels of antibodies in the blood. When used to complement conventional veterinary treatments, plasma therapy shortens the course of treatments, reduces hospitalisation periods and lessens the quantity of drugs required to treat a wide variety of medical conditions. Plasma therapy also has a host of preventative applications.

The blood of all mammals has four key constituents:

  1. Red cells - cells responsible for transporting oxygen from the lungs to body tissues
  2. White cells - cells responsible for producing antibodies that counteract infectious microorganisms
  3. Platelets - cells that aid the clotting process
  4. Plasma - the liquid component of blood containing proteins, antibodies or gamma-globulins, clotting factors and a variety of other immunity-boosting agents

The liquid portion of uncoagulated mammalian blood that is free of cells is known as plasma.

VIL products contain hyperimmunised plasma, a form of plasma that has greatly increased levels of antibodies. Hyperimmune plasma can only be obtained from donors subject to a formal hyperimmunisation regimen. This involves the strategic administration of a variety of commercial and proprietary vaccines enabling VIL products to target specific active infections. In response to hyperimmunisation, donors accumulate levels of antibodies in their bloodstream 2-3 times higher than those of normal animals.

Plasma is extracted from blood samples using a complex centrifugal process. In order to obtain plasma sufficiently rich in gamma-globulins (antibodies), VIL plasma is derived solely from the blood of hyperimmunised donors.
