Description
Why It’s Done:
The IHC – CD5 test is ordered to:
1. Diagnose Lymphomas:
o Differentiate between types of lymphomas, such as chronic lymphocytic leukemia (CLL) or mantle cell lymphoma.
2. Classify Lymphoid Cells:
o Determine the cell lineage (T-cell vs B-cell) in lymphoid malignancies.
3. Guide Treatment Decisions:
o Helps oncologists decide on the best treatment strategy based on lymphoma type.
4. Evaluate Tissue Samples:
o Confirm the presence and extent of disease in biopsies.
Preparation:
• Patient Preparation:
o No special preparation is required by the patient since this test is performed on a tissue biopsy sample already collected.
• Sample Collection:
o A tissue biopsy is obtained via surgery or needle biopsy and sent to the pathology lab for analysis.
• Information for Lab:
o Provide clinical history and relevant details to the pathologist to aid interpretation.
