We have excellent sucess in decalcifying the bone prior to processing. We make sure the core has been in fixative for 2 hrs prior to the 20 mins in the decal solution (DeCal STAT). It is then rinced in water and placed in line for standard processing.

How long is the specimen in formalin before you put it in Cal Rite decal? Thanks.

We process bone marrow biopsies the same day received. We use a combination decal/ fixative solution (Cal Rite decal) with good results. We keep in this solution a minimum of 3 hours before moving to
tissue processor where first 2 solutions are a total of 3 hours in
formalin. Although most bone marrow biopsies are received by 2:00 - 3:00pm; we've had some received as late as 4:00pm with good results.
Our clinicians place the bone marrow core in pre-filled formalin at the
point of collection, also.
The Cal Rite is a combination of formaldehyde, formic acid and methanol.

Subject: [Histonet] decalcifying bone marrows after processing
I was wondering if anyone has any experience with, or is it even possible to, decalcify bone marrows after they are processed. Our pathologist would like to be able to process bone marrows the same day we receive them, but most of the time there just isn't enough time to allow for proper fixation and then proper decalcification. She asked if we could process them and then decalcify and I have yet to find an answer to this question. Please help!!
