How much PRP do you actually get from your blood?

The amount of platelets that are derived by each milliliter of blood drawn will vary by patient, but it will also vary by extraction technique. Most offices will used advanced centrifuge systems for preparation of Platelet-Rich Plasma. Offices that provide PRP will concentrate their platelet-plasma concentrations differently. The amount of PRP that you will receive will depend more on how much blood is drawn and used, versus how much plasma is accumulated for injections. Best, Dr. Anil Shah

Unfortunately to date there is no standard protocol related to the preparation and administration of PRP (e.g. amount,depth of injection,time between treatments,etc). Most hair related data indicates that the ideal platelet concentration is about 3-4 times normal. The amount of PRP obtained is roughly about 1/3 the amount of blood drawn (so if 30cc of blood are drawn we end up with about 10cc of PRP)

There are no peer reviewed studies to determine which concentration is most effective. As you can see, some doctors believe that higher concentrations work better. I feel it is not the concentration but the total number of platelets delivered that is important. Furthermore, there are three other factors. Firstly,  red blood cells and white blood cells are not helpful. Secondly, cytokines and other factors in the plasma are functional. Thirdly, the injection technique makes a difference. I prefer the subdermal Depo injection. Find a PRP expert. Good luck
