Which techniques are used in urinalysis?

• A. Visual inspection only
• B. Dipstick testing and microscopic analysis
• C. Blood tests
• D. X-ray imaging

Answer: (B)

Urinalysis relies on two complementary techniques: chemical analysis using dipstick strips and microscopic examination of the urine sediment. The dipstick provides rapid, semi-quantitative data on substances such as pH, specific gravity, protein, glucose, ketones, blood, leukocyte esterase, and nitrites, offering clues about infection, diabetes, kidney or liver problems, and dehydration. Microscopic analysis then looks at the urine sediment under a microscope to identify red and white blood cells, bacteria, crystals, casts, and epithelial cells, which helps pinpoint infections, stone disease, glomerular or other kidney issues. Visual inspection of color and clarity alone is insufficient to detect many abnormalities, so combining chemical screening with microscopic analysis gives a more complete evaluation. Blood tests analyze substances in the blood, not urine, and X-ray imaging is an imaging method for anatomy, not a urinalysis technique.
