PRP centrifuge and PRP quality: Differences in type or brand of centrifuge, quality of the PRP produced and effectiveness?

PRP is basically your own blood product. There are different techniques to obtain PRP but it mostly has to do with companies selling different products to doctors (and patients) claiming their method is "the best".You can still obtain PRP the old fashion way using regular lab centrifuge machines with minimal technical skill.  A great cook can make great meals without fancy kitchen equipment as long as they have great ingredients. 

Originally, PRP was produced in a standard blood/lab centrifuge using blood collection tubes.  This required a lot of technically precise labor, variability in centrifuge speed and typically yields only 1 ml of prp per tube.   There are now several systems that allows for more controlled concentration of prp.  My personal two favorite are the harvest and emcyte systems, they each allow for a yield of 3-6ml of prp per treatment.   However the cost to the practice per use is significantly higher than traditional methods or some other machines, but is well worth the better quality and quantity of prp in my opinion.  Don't be fooled by some systems that claim they can generate 6ml of prp from 10ml of blood, thats not mathematically possible, thats just Plasma not PRP.
