Test ID: SPSM Morphology Evaluation (Special Smear), Blood

Reporting Name

Morphology Eval (special smear)

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

Clinical Information

Under normal conditions, the morphology and proportion of each blood cell type is fairly consistent in corresponding age groups. The morphology and proportion of each blood cell type may change in various hematologic diseases. Differential leukocyte count and special smear evaluation is helpful in revealing the changes in morphology or proportion of each cell type in the peripheral blood.

Interpretation

The laboratory will provide an interpretive report of percentage of white cells and, if appropriate, evaluation of white cells, red cells, and platelets.

CBCN CBC without Differential Yes No

Testing Algorithm

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

 

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

Analytic Time

1 day

Day(s) and Time(s) Performed

Sunday through Saturday; Continuously
