What does a high power examination (400x) identify?

A high power examination, such as at a magnification of 400x, is particularly effective for closely inspecting individual cells. This level of magnification allows for the detailed observation of cellular morphology, including cell size, shape, and arrangement. It is essential for distinguishing different types of cells based on their individual characteristics.

In cytology, this means that one can identify abnormal cells that may indicate disease processes, such as cancer or infections, and can also help to discern whether cells are benign or malignant. This function is critical in diagnostic pathology. The ability to characterize and compare individual cells is what sets this level of magnification apart, as it provides the necessary detail needed to make accurate assessments about cell types and their potential implications for health.

Other options are less relevant at this magnification. For instance, larger tissue sections cannot be adequately observed at this power, and while staining quality is essential, the primary focus of high power examination is the cells themselves rather than simply assessing staining. Locating cellular debris may occur, but this is not the main purpose of high power examination compared to the critical evaluation of individual cells.
