How Long Does Plasma Treatment Last?

February 1, 2024

Plasma is an irreplaceable resource that can’t be manufactured in a lab. Because of this, plasma needs to be donated consistently in order to meet the demands of patients in need. Below, we’re breaking down just how long plasma treatment lasts, so you have a better idea of how frequently plasma needs to be donated to support patients in need. 

The Basics of Plasma Treatment

Plasma, the liquid component of blood, is rich in proteins, antibodies, and clotting factors. This “liquid gold” is a valuable resource, used to treat a variety of medical conditions, ranging from immune deficiencies to neurological disorders. Don’t worry – we’ll break down all of this medical terminology below! 

Plasma treatment involves collecting and processing plasma from donors, then using it to create life-saving therapies. These therapies can be administered to patients through infusion, helping them to treat and manage various illnesses. The duration of the effectiveness of plasma treatment can vary depending on the specific condition being treated, and the individual patient. In our guide below, we’re diving into how long plasma treatment is effective when it comes to specific treatments and conditions. 

How Long Does Plasma Treatment Last For Different Conditions? 

Immune Deficiencies

Plasma treatments can be used to help boost the immune system of patients with autoimmune disorders and immune deficiencies. The positive effects of these treatments can help to protect patients against infection for several weeks. 


Plasma is commonly used to treat patients with hemophilia. Hemophilia, an inherited blood disorder where blood doesn’t clot properly, can be treated with plasma-derived clotting factors. When it comes to hemophilia, plasma treatment can be effective for several days to a couple of weeks depending on the type of clotting factor that the patient receives as treatment. 

Neurological Disorders

When it comes to neurological disorders like Acute Transverse Myelitis (ATM), Autoimmune Encephalitis or Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), plasma exchange can be a supportive treatment to help manage symptoms. While the duration of its effectiveness depends on the condition and the specific case, patients can experience improved symptoms over the course of weeks or even months.

Treating Trauma Victims

Plasma treatment can be used to help burn and trauma victims recover after accidents. The length of the plasma treatment’s effectiveness depends on the severity of the injuries. In some cases, the patient might need multiple injuries over time to fully heal and recover. 

Plasma’s effectiveness – and the amount of time that a plasma protein therapy or treatment lasts for – is case by case specific. It depends on the condition, ailment, or issue being treated. The one fact that remains true regardless of any other factors? Plasma donation is required consistently to keep up with the demand from patients across Canada.
