Our Donors

We use a closed herd of donor horses. Prior to acceptance into the herd, the animals are screened for their suitability to be donors by ensuring that they are free from diseases which might be transmitted in plasma and the horses are "universal" plasma donors by testing for haemolysins and anti-red cell antibodies.


Collection of plasma is by the process of plasmapheresis. This completely closed process using wholly disposable equipment ensures sterility and freedom from endotoxins by permitting the plasma to be harvested directly from the animal into the plasma bags.

Veterinary Immunogenics Ltd continues to adhere to the single donor approach which eliminates any additional handling such as mixing or pooling of plasma. It allows each bag of plasma to be frozen immediately after collection and ensures accurate traceability while removing all risk of cross contamination.

Our regulated process ensures continuing product quality, safety and efficacy. Each harvest is subjected to sterility testing and is constantly monitored to ensure freedom from known viruses. Plasma is collected directly into one litre sterile plasma bags which are immediately uniquely numbered, enclosed in bubble-wrap and placed in the freezer at -25C.


The licensed shelf life of the frozen product is two years from the date of harvesting when stored at -25C. Veterinary Immunogenics storage of plasma is monitored and validated continually.

Independent Validation

To ensure the presence of high levels of immunoglobulin (specifically IgG), following many years of development, a special strict routine vaccination procedure is utilised. Samples from every harvest are submitted to outside GLP laboratories to accurately measure IgG, total protein, sterility and freedom from virus.
