Specimen Type Describes the specimen type needed for testing

Varies

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.

Forms: Hematopathology Patient Information Sheet (Supply T676) in Special Instructions

 

Body fluid or spinal fluid specimens must arrive within 96 hours of collection.

 

Submit only 1 of the following specimens:

 

Specimen Type: Body fluid

Container/Tube: Sterile container

Specimen Volume: At least 5 mL

Collection Instructions:

1. If the volume is large, pellet cells prior to sending.

2. Send less volume at ambient temperature or as a frozen cell pellet.

Specimen Stability Information:

Body fluid: Ambient/Refrigerated/Frozen

Cell pellet: Frozen

 

Specimen Type: Paraffin-embedded bone marrow aspirate clot

Container/Tube: Paraffin block

Specimen Stability Information: Ambient/Refrigerated

 

Specimen Type: Frozen tissue

Container/Tube: Plastic container

Specimen Volume: 100 mg

Collection Instructions: Freeze tissue within 1 hour of collection.

Specimen Stability Information: Frozen

 

Specimen Type: Paraffin-embedded tissue

Container/Tube: Paraffin block

Specimen Stability Information: Ambient/Refrigerated/Frozen

 

Specimen Type: Spinal fluid

Container/Tube: Sterile vial

Specimen Volume: 5-10 mL

Specimen Stability Information: Ambient/Refrigerated/Frozen

 

Specimen Type: Extracted DNA from blood or bone marrow

Container/Tube: 1.5- to 2-mL tube with indication of volume and concentration of DNA

Specimen Volume: Entire specimen

Collection Instructions: Label specimen as extracted DNA from blood or bone marrow

Specimen Stability Information: Refrigerated/Ambient

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.

Body Fluid or Spinal Fluid: 1 mL/Tissue: 50 mg/Extracted DNA from Blood or Bone Marrow: 50 microliter at 20 ng/microliter
