In a client diagnosed with multiple myeloma, what laboratory finding is specifically recognized?

A laboratory finding that is specifically associated with multiple myeloma is an increased calcium level. This condition often leads to bone resorption due to the proliferation of malignant plasma cells in the bone marrow, which results in increased levels of calcium in the blood (hypercalcemia). The release of calcium from the bones can occur as the structural integrity of the bone is compromised by the myeloma cells, making hypercalcemia a significant indicator of the disease's progression and complications.

While decreased red blood cell count, low hemoglobin level, and elevated liver enzymes might be observed in patients with multiple myeloma, they are not unique to this condition. Decreased red blood cell counts and low hemoglobin levels can relate to anemia, which can arise in various conditions, including chronic disease or other malignancies. Elevated liver enzymes typically indicate hepatic issues, which might not be directly related to multiple myeloma. Thus, increased calcium levels serve as a more specific marker for the pathology associated with this particular hematological malignancy.
