Human blood consists mainly of the liquid based plasma along with small solid components, which include Red Blood cells, White Blood cells and platelets. The platelets help in the clotting of blood and they are rich in proteins called growth factors, which helps in the healing process.
Platelet Rich Plasma or PRP is the plasma with higher concentration of platelets than normally found in the blood. The concentration of platelets in PRP is around 5 to 10 times higher, when compared to normal blood.
The first step is to draw blood from the patient, and then the platelets are separated from the other blood cells. The concentration of platelets is then increased by using the process of centrifugation.
The increased concentration of the growth factors present in the Platelet Rich Plasma (PRP) helps in speeding up the healing process. The PRP is applied to the injured area to speed up the healing. This can be administered using the following processes:
