What is the role of cytology stains in identifying myeloma cells?

Cytology stains play a pivotal role in highlighting cell morphology, which is crucial for identifying myeloma cells, particularly in the context of diseases like multiple myeloma. Staining provides contrasting colors to different cellular components, enabling pathologists to observe the distinct features of these abnormal cells under a microscope.

Myeloma cells, or neoplastic plasma cells, often exhibit unique morphological characteristics such as increased size, irregular shapes, and specific cytoplasmic features that can be visualized effectively with cytology stains. Analysts use various staining techniques to differentiate these malignant cells from normal cells based on their structure and appearance.

While other options mention important laboratory techniques, they do not specifically address the primary function of cytology stains in the identification process of myeloma cells. For instance, measuring cell proliferation is more relevant to assessing growth rates rather than identifying specific cell types, detecting genetic mutations focuses on molecular aspects that aren't visible through staining, and evaluating enzyme activity requires different assays rather than morphological techniques.
