Specimen Type Describes the specimen type needed for testing

Bone Marrow

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Provide a reason for referral with each specimen. The laboratory will not reject testing if this information is not provided, but appropriate testing and interpretation may be compromised or delayed.

 

Container/Tube: Green top (sodium heparin)

Specimen Volume: 2-3 mL

Collection Instructions:

1. It is preferable to send the first aspirate from the bone marrow collection.

2. Invert several times to mix bone marrow.

3. Other anticoagulants are not recommended and are harmful to the viability of the cells.

Additional Information: Advise Express Mail or equivalent if not on courier service.

Forms: If not ordering electronically, please submit the following forms with the specimen:

-Hematopathology/Molecular Oncology Request Form (Supply T241)

-Cytogenetics Hematologic Disorders Request Form (Supply T607)

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
