[Histonet] ISH kappa lambda on bone marrow core biopsy

[Victoria Baker]

Good morning!

Just recently we started having an issue with a heavy blue precipitate on
our bone marrow cores.  We have changed nothing in our protocol and even
did parallel testing with a reference lab.  Both had the precipitate, but
to a lesser intensity.

Has anyone else been seeing this?

Thank you in advance any and responses are appreciated.
