Test Code SPSM Morphology Evaluation (Special Smear), Blood


Necessary Information


Clinician should provide indication for performing test.



Specimen Required


Collection Container/Tube: 2 slides

Specimen Volume: 2 unstained, well prepared peripheral blood smears

Collection Instructions: Smears made from blood obtained by either a lavender top (EDTA) tube or finger stick specimen


Useful For

Detecting disease states or syndromes of the white blood cells, red blood cells, or platelet cell lines of a patient's peripheral blood

Testing Algorithm

If clinically abnormal results are identified by microscopic examination, a peripheral blood smear review is performed by a Hematopathologist at an additional charge.

 

If patient has not had a complete blood cell count in the last 3 days, one will be performed at an additional charge.
