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

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.

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.
