Which of the following is NOT a component of a urinalysis?

In a typical urinalysis, key components evaluated include specific gravity, protein levels, and pH level, as they provide valuable insights into a patient's kidney function and overall health.

Specific gravity measures the concentration of solutes in urine, helping to assess the kidney’s ability to concentrate urine. Protein levels in urine can indicate kidney damage or disease, specifically glomerular disorders. The pH level measures the acidity or alkalinity of urine, offering clues about a person's metabolic status and potential urinary tract issues.

Blood sugar levels are not a component of a standard urinalysis. While glucose levels can be tested in urine (and may be indicative of diabetes when elevated), they are not part of the basic assessment during a standard urinalysis, which primarily focuses on physical, chemical, and microscopic analysis of the urine itself. Therefore, the inclusion of blood sugar levels is not typically associated with urinalysis.
