Specimen Type Describes the specimen type needed for testing
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.
Sources: Tissue or biopsy of heart valve, liver, lymph node, or spleen. Tissue specimen fixed in a paraffin block or ocular specimen (eg, vitreous humor fluid) is also acceptable.
Container/Tube: Sterile container
Specimen Volume: Entire collection
Specimen Stability Information:
Frozen (preferred)/Refrigerated <48 hours-Fresh tissue
Ambient (preferred)/Refrigerated-Paraffin block
Refrigerated (preferred)/Frozen-Vitreous humor or ocular fluid
Additional Information: The high sensitivity of amplification by PCR requires the specimen to be processed in an environment in which contamination of the specimen by Bartonella species DNA is not likely.
Forms: If not ordering electronically, submit a Microbiology Request Form (Supply T244) with the specimen.
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.
Tissue: 5 mm(3); Ocular fluid: 0.5 mL
Tissue in formalin, formaldehyde or acetone
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
