Urine analysis
Urine Analysis
Urine analysis (pronounced: yoo-rin uh-nal-uh-sis), also known as urinalysis, is a series of tests performed on a urine sample to detect various substances and cells that can provide important information about the body's health.
Etymology
The term "urine analysis" is derived from the Latin word "urina", which means "urine", and the Greek word "analysis", which means "a breaking up or loosening".
Procedure
A urine analysis involves three parts: visual examination, chemical examination, and microscopic examination.
- Visual examination evaluates the urine's color and clarity.
- Chemical examination uses a dipstick to test for various substances in the urine, such as glucose, protein, and red and white blood cells.
- Microscopic examination involves viewing a small amount of urine under a microscope to look for cells, crystals, and other substances.
