Before beginning other diagnostics of the urine, a gross examination of urine is recommended.

• A. Darkfield
• B. Gross
• C. Taste
• D. Microscopic

Answer: (B)

Macroscopic (gross) examination is the first look at urine with the naked eye. It quickly assesses color, clarity, odor, and foam, which can give immediate clues about hydration status (dark urine suggests concentration from dehydration), infection (cloudy urine), bleeding or pigment changes (reddish or brown urine), or protein presence (foam). This quick, inexpensive check helps guide what to test next and whether more detailed analyses are needed. The other options are more specialized: darkfield is a technique for viewing certain organisms under special illumination and isn’t a standard initial screening; microscopic analysis provides detailed cell, crystal, or bacterial counts but is typically done after the gross exam when indicated; tasting urine is not a valid or safe diagnostic method.
