The visual assessment of urine color is the first step in a Complete Urine Examination (Physical) Routine. Standard color is due to the pigment urochrome. Changes in color can provide immediate diagnostic clues regarding hydration status, metabolic disorders, presence of blood, or the intake of specific drugs and foods.
Why Context Matters
Urine color is highly subjective to the technician's interpretation and can be altered by non-pathological factors such as riboflavin (B2) supplements (neon yellow), beets (red/pink), or certain medications like Rifampin (orange).
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
