Which test would be unlikely to add new information when performing an initial malignancy workup?

• A. ALKALINE PHOSPHATASE
• B. CMP
• C. CBC
• D. CT CHEST/ABD/PelVIS

Answer: (A)

In an initial cancer workup, you want tests that quickly reveal whether disease is present, where it is, and how organs are functioning. CBC and CMP provide broad systemic information—anemia, infection, electrolytes, liver and kidney function—that helps shape immediate management. A CT scan of chest, abdomen, and pelvis gives concrete anatomic details about tumor location, nodal involvement, and metastases. Alkaline phosphatase, while it can be elevated with bone or liver involvement, is non-specific and does not localize disease. It can be influenced by benign conditions and age, so it often doesn’t change the initial diagnostic or treatment plan. Therefore, alkaline phosphatase would be unlikely to add new information beyond what the CBC, CMP, and CT imaging already provide.
