Which test is not typically used as part of lymphoma staging?

• A. Lymph node biopsy
• B. CBC
• C. Electrolytes
• D. Bone density scan

Answer: (D)

Staging lymphoma focuses on mapping where the disease has spread and how it’s affecting organ function to guide treatment. A lymph node biopsy provides the definitive tissue diagnosis and helps determine extent of nodal involvement, which is central to staging. A complete blood count gives essential information about blood cell levels that can reflect marrow involvement or systemic impact of the disease, influencing staging and treatment decisions. Measuring electrolytes and kidney function helps assess the patient’s overall physiologic status and readiness for therapy, including risks like tumor lysis or treatment-related toxicity, which informs staging and planning as well. A bone density scan, on the other hand, measures bone mineral density and osteoporosis risk; it does not reveal lymphatic spread or tumor burden and is not part of lymphoma staging.
