Roles of White & Red Blood Cells in PRP

White and red blood cells in platelet-rich plasma (PRP) treatment
Red and white blood cells are separated during PRP preparation to create a platelet-rich plasma sample for treatment.

Platelet-rich plasma (PRP) is prepared from a person’s own blood and contains a concentrated number of platelets along with varying amounts of other blood components. Understanding the roles of red and white blood cells can help explain why different PRP preparations may exhibit distinct characteristics.

What Role Do Red Blood Cells Play?

Red blood cells primarily carry oxygen throughout the body. During PRP preparation, the goal is generally to separate and concentrate platelets while reducing the amount of red blood cells in the final preparation.

The amount of red blood cells remaining can vary depending on the preparation method. Their presence may influence the characteristics of the PRP product and is therefore one factor considered when preparing PRP for clinical use.

What About White Blood Cells?

White blood cells are part of the body’s immune system and help respond to injury and infection. Unlike red blood cells, their presence in PRP can be intentionally varied depending on the type of preparation used.

Some PRP preparations contain relatively higher concentrations of white blood cells, while others are designed to contain fewer. The appropriate composition may depend on the condition being treated and the clinical approach being used.

Why Does PRP Composition Matter?

A platelet-rich plasma injection is not necessarily identical from one preparation to another. Differences in platelet concentration and the amounts of red and white blood cells can affect the biological characteristics of the final product.

For example, a PRP injection for the shoulder may be prepared differently depending on the treatment approach and the condition being addressed. PRP is also distinct from stem cell therapy and stem cell treatment, which involve different biological approaches and should not be considered interchangeable.

Patients are encouraged to talk to a healthcare professional about the selected PRP method, its potential benefits and drawbacks, and whether it suits their medical condition.
