Sample Requirements
Specimen: Bone Marrow
Container(s): See policy for complete details
Preferred Vol: See policy for complete details
Minimum Vol: See policy for complete details
Note: After collection, biopsies are placed on a sterile pad. The pad is wrapped in a piece of sterile gauze that has been moistened with sterile saline and placed in a sterile specimen cup. Biopsy specimens should be processed as soon as possible so they do not dry out. Specimens are held at room temperature. The specimens must be properly labeled (including patient identification and specimen type). A completed requisition must accompany the specimen. Bone Marrow specimens should be delivered to the lab and processed as soon as possible. All bone marrow specimens obtained should be sent to the laboratory, even if the samples are hold samples.
Processing Instructions
Reject due to: n/a - send to lab
Spin: N
Aliquot: N
Temp: RT
Storage location: Requires immediate processing by CPA. CPA - Order "BM SPEC" and match with completed requisition. M - F until 1700, transport specimen, requisition, and labels to the Cell Markers Lab (station #181); call before tubing specimen to make sure there is someone available to do testing. After hours M - Sat and all day Sun and Holidays - Give BM to Core Hematology. If you have any questions, call the pathologist on call.
Completed requisitions will accompany all specimens from Hem Clinic. Surgery bone marrow requisitions are often sent days before they collect the sample. These requisitions are stored in the 'Bone Marrow binder' on the CPA bookshelf. When a Bone Marrow specimen arrives from surgery, it will arrive with a blue specimen information sheet. Please match up the blue sheet and sample with the requisition from the binder before delivering the sample/paperwork.
Off-site collection: see full instructions under "Bone Marrow Aspirate" listing.

Description
The bone marrow aspiration/biopsy is used to diagnose or rule out hematologic and/or oncologic diseases. These tests are performed for staging and monitoring treatment for many hematologic and non-hematologic disorders. Bone Marrow biopsies are often indicated for solid tumor staging; bilateral specimens are often obtained in that setting. Biopsies may also be particularly useful in the case of a "dry tap" (see Seattle Children's Clinical Policy/Procedure: Bone Marrow Aspiration-Biopsy)
Requisition
Complete & include copy of online HemOnc Bone Marrow Requisition (cases to be evaluated by Seattle Children's Pathology) or Hematopoietic Transplant Marrow Requisition (specimens to be evaluated at Seattle Cancer Care Alliance), as appropriate.
For specimens collected off-site, see "Bone Marrow Aspirate" listing.
