Platelet Rich Plasma (PRP) has been used in medicine for a number of years. It’s a “spill-over” from sports medicine into aesthetics medicine and skin rejuvenation. In the past few years it has entered the field of medical treatment of hair loss.
In sports medicine it has been used to speed up healing and improve overall results following sports injury. It has proven very useful in the field. In recent years PRP has been more widely used and increasing number of studies support the role that PRP can play in various areas of medicine.
Our PRP Procedure
To understand how it works, we need to look at the role that platelets play when the body sustains an injury or trauma. When the body sustains an injury, surgical or traumatic, it starts a chain reaction and platelets are often among the first cells on the scene to take charge. If injury leads to bleeding the platelets will first obtain hemoestasis – ie stop the bleeding. Stopping the bleeding is not enough as the injury needs to repaired. The platelets directly or indirectly lead to the release of various substances and signals that will form a vital part of further repair and healing. In normal whole blood the concentration of platelets is 150,000-400,000 platelets per microlitre of blood with an average of around 200,000 platelets/mcl.
When whole blood is centrifuged around 45% of the volume will settle in the bottom of the blood tube as Red Blood Cells (RBC). Above RBC we find blood plasma. Plasma is the 55% of the volume of the whole blood that is lighter in weight and therefore floats above the RBC. The plasma also contains the platelets. We thus have 100% of the platelets in 55% of the volume – which translates to x1.8 higher concentration of platelets in the plasma than in the whole blood. This could and is principally Plalet-Rich-Plasma and it could be used “as is”. However, we can obtain even higher degrees of platelet-concentrations. If the plasma (the yellowish 55% volume floating above the RBC) is separated and spinned again, then the plasma will separate further into a lower portion of plasma with most/all of the platelets called PRP and a portion of plasma above with far less platelets which is termed Platelet-POOR-Plasma or PPP. Say if 20% of the lower portion is used we’d have a PRP with nearly x5 higher concentration of platelets as compared to whole blood. With such a high concentration of “repair/healing/growth/collagen-stimulating” cells injected into a relatively small area the area gets a boost that is far beyond what the tissue would otherwise receive in normal capillary blood vessels.
