Overview
Laboratory tests for splenic marginal zone lymphoma include complete blood count (CBC), blood chemistry studies, cytogenetic analysis, flow cytometry, immunohistochemistry, genetic testing, FISH, PCR, and immunophenotyping.
Laboratory tests
Laboratory tests for splenic marginal zone lymphoma (SMZL) include:[1]
- Complete blood count (CBC) with differential count
- Pancytopenia or leukemic presentation with leukocytosis, anemia, thrombocytopenia[2]
- Serum albumin levels
- serum LDH levels
- Beta-2-microglobulin
- Immunohistochemistry[3]
- Typically positive for CD20,CD79a, BCL-2 and immunoglobuin M (IgM).
- Surface immunoglobulin D (IgD) and DBA44 are variably expressed.
- Negative for CD5, CD10, CD43, CD103, CD123, Annexin A1, BCL-6 and LEF-1.
- Genetic testing[4]
- Chromosomal 7q32 deletion (30-40%).
- Chromosome 3q gains (20-30%)).
- NOTCH2 and KLF2 are the commonly reported gene mutations.
- Flow cytometry[5]
- FISH (fluorescence in situ hybridization)[6]
- PCR[7]
