Test Overview
Direct immunofluorescence using flow cytometric techniques.
Confirmation of diagnosis and immunophenotype in acute and chronic leukemias and lymphomas. See http://www.pathology.med.umich.edu/handbook/Tables/Flow_Cytometry_Panel… for all Flow Cytometry Panels.
Pathologist interpretation of results provided.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Requires an adequate number of viable cells for analysis. When cell counts drop below 5 cells/cmm and

<ul><li><li>
Relevant clinical history
Clinical or morphological findings and suspicions
Specimen source
Date and time of collection
Phone number and after hours pager number for ordering physician
</ul>
<b>BONE MARROW ASPIRATE: </b>
<ul><li>
Add 1 - 2 ml of first pull bone marrow aspirate to a green top sodium heparin Vacutainer® tube.<li> Send intact specimen at room temperature within 12 hours of collection.<li>
Include 4 unstained aspirate smears
Include an unstained peripheral blood smear
Include a copy of the patient's most recent White Blood Cell and platelet counts, and peripheral blood differential.<li>
</ul>
<b>BODY FLUID and CSF: </b>
<ul><li>

Additional Information
Test includes pathologist interpretation of results billed as a separate additional charge. This test is not available without interpretation. Additonal markers will be run if clinically indicated. Measurement of TdT may be an adjunct to the diagnosis of some leukemias and lymphoblastic lymphomas and will be run at the discretion of the hematopathologist at an additional charge. By ordering this test the clinician acknowledges that additional reflex testing will be performed and billed at a separate additional charge if indicated. For consultation, contact the MLabs Client Services Center or Flow Cytometry Laboratory at 76-39420.
