Test Your Knowledge on Clinical Urinalysis

Clinical Urinalysis: Key Concepts and Principles

• Specific gravity of urine from a patient with polyuria can indicate the need for evaluation for diabetes insipidus.
• Unpreserved urine specimens left at room temperature for several hours can result in decreased glucose and ketones, increased bacteria and nitrite, and increased cellular elements.
• Red blood cells disintegrate more rapidly in concentrated and acidic urine.
• A negative urine pregnancy test performed on a random specimen may need to be repeated using a first morning specimen.
• Diuretic use can result in polyuria.
• The renal threshold for glucose is between 160-180 mg/dL.
• Increased production of vasopressin can produce a low urine volume.
• Osmometers utilizing the freezing point colligative property of solutions are based on the principle that 1 osmole of nonionizing substance dissolve in 1 kilogram of water lowers the freezing point 1.86oC.
• The PAH test is dependent on glomerular filtration and tubular secretion.
• Dark yellow-amber-colored urine may contain increased amounts of bilirubin.
• Specimens from patients receiving treatment for UTI frequently appear cloudy and red.
• A 2-hour postprandial urine should be collected 2 hours after eating.
