Urinalysis refers to the examination of urine to detect and diagnose various medical conditions. It involves analyzing the physical, chemical, and microscopic properties of urine. This diagnostic test can provide valuable information about kidney function, urinary tract infections, liver disease, diabetes, and other health issues. By examining the components of urine, such as pH, specific gravity, protein levels, glucose levels, and the presence of red or white blood cells, urinalysis helps healthcare professionals in assessing a patient's overall health and determining the appropriate course of treatment.
