Defect in the lab tube used for prp collection and separation.The is a gel layer that separates the plasma from rbc.The plasma is aspirated from the tube and used for reinjection in aesthetics to rejuvenate the skin.When i aspirated the prp there was a chunk of the gel separator that displace and was, unknowingly at the time (because it was all yellow and appeared to be plasma, but after it had set awhile and the plasma is now clear, you can clearly see the chunk of white gel) with my prp.Having this in the plasma and in contact with my needle when aspirating had caused a severe allergic reaction at injection sites.After treatment with oral and injected steroids the inflammation has resolved but there are persistent visible and palpable nodules under my skin at injection sites from this gel that was in my unknowingly in my prp.Fda safety report id# (b)(4).
