Is this new PRP dosing math? Help! I just got this from a patient who had a procedure at another clinic. I asked for the clinic note to see what was done so I could better advise the patient. Here is what the doctor told me: He drew 156cc of blood with 24cc of ACD-A....total 180cc Starting platelet count of 281. He created 15cc of PRP at a platelet count of 4630 (yes that is right). I had to stop there because the Maff does not work. Even if the initial draw was all blood the total platelets would be 180cc x 281 = 50.6 Billion platelets. The PRP numbers he gave me: 15cc x 4630 = 69.5 Billion platelets. So the process created nearly 20 Billion platelets! This is more than a rounding error in my opinion. I want this centrifuge 😀
Looks like my accountants math 😉
As someone way smarter than I once said, “that math doesn’t math”
That’s haemochromatosis venesection levels 😂
Wow, those numbers are quite surprising!
That centrifuge is a platelet factory 🤣

5moLikely that was the count of the PRP produced (maybe 2-6cc?) and then it was diluted with PPP to 15 cc. Based on what you said it was an Angel spin. 16x is high but not unheard of for that system depending on %HCT setting. Would need PRP volume produced before PPP added to get accurate plt count.
