SPSM - Specimen: Morphology Evaluation (Special Smear)

Test Catalog

Test ID: SPSM    
Morphology Evaluation (Special Smear)

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

For MML patients, a physician review is included if clinically abnormal results are identified by microscopic examination.

For Mayo patients, a consultant evaluation is performed if clinically abnormal results are identified by microscopic examination (at an additional charge).

Specimen Type Describes the specimen type needed for testing

Whole blood

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.

Container/Tube: Slides

Specimen Volume: 5 unstained, well-made peripheral blood smears (fingerstick blood)

Collection Instructions: If peripheral blood smears (fingerstick blood) is not available, a smear from EDTA blood will be accepted.

Additional Information: Include complete blood count results (if available) and reason for referral.

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.

Smears: 2

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected


Mild OK; Gross reject







Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
