Is this a DRK sleeve patch?

[JERSEY 34]

Here is another of the items left with me by a collector who wants to do a trade for something I have. Unfortunately a lot of what he has appears to be fake are damaged. I believe this is a sleeve patch for the DRK, but is it real. I would appreciate it if you could let me know. I think it may be ok, but need to know for sure.
Thanks in advance.

DRK emblem worn on upper right arm by male Red Cross uniformed personnel. Not sure if original though.
