Rosna Kerdson: The Role of Plasma in Modern Medicine

Rosna Kerdson, GSU Welcome Executive at University of Greenwich, shared a post on LinkedIn:

“The role of plasma in modern medicine

I’ve recently been learning more about plasma, and I didn’t realise just how important it is in modern healthcare.

Plasma makes up around 55% of our blood volume and contains essential proteins, antibodies and clotting factors. These components can be used to produce therapies for people living with conditions such as primary immune deficiencies and haemophilia.

One statistic that particularly stood out to me was the number of donations required to produce these treatments. According to CSL Plasma, a patient with primary immune deficiency may rely on around 130 plasma donations for one year of medicine, while a patient with haemophilia may require around 1,200 donations.

It really highlights how something found naturally within our blood can become an important part of treatments that help people manage serious and long-term conditions.

As someone interested in biomedical science and the immune system, I find it fascinating how our understanding of components such as plasma and antibodies continues to contribute to modern medicine.”
