During a physical examination of urine, the primary focus is on observing its macroscopic characteristics, which includes evaluating the color, appearance, and specific gravity.

The color of urine can indicate various health conditions; for example, dark yellow urine may suggest dehydration, while very pale urine can indicate overhydration. The appearance of urine can help in identifying the presence of substances such as blood or pus that may suggest an underlying pathological condition. Specific gravity measures the concentration of solutes in the urine, providing insight into kidney function and hydration status. High specific gravity might indicate concentrated urine due to dehydration or certain diseases, while low specific gravity may suggest an inability of the kidneys to concentrate urine.

The other options, while important in the overall analysis of urine, are typically evaluated through chemical analysis rather than the physical examination phase. Protein levels and glucose concentration, for instance, are determined using tests that involve chemical reactions, not merely visual inspection. Similarly, urea and creatinine concentrations, as well as electrolyte levels, are quantitatively measured and require specific laboratory techniques that go beyond the physical examination. Thus, the physical examination is distinctly focused on the observable, macroscopic traits of the urine.
