What is UA?
UA stands for urinalysis. Urinalysis is the sampling and analysis of urine.
Why Is Urinalysis Done?
Urinalysis is used to detect urinary tract infection, kidney problems, diabetes and many other disorders. Urinalysis is a common test that is routinely performed before surgery. It is also part of routine medical examinations or used upon admission to a hospital to assess a patients overall health and screen for a variety of disorders. A doctor may order a urinalysis if his patient is experiencing stomach pain, back pain or urination problems.
How Is A Urinalysis Done?
The patient provides a urine sample for urinalysis in a container provided by the doctor or laboratory. It is important for the patient to tell the doctor all drugs, vitamins and supplements that he/she is taking before a urinalysis as they can affect the results of a urinalysis. The best samples are those that are collected early in the morning or when the urine is the most concentrated. The urine sample is then sent to a laboratory for analysis. The urine sample will be analyzed by a trained lab technician by a visual examination, a dipstick test and a microscopic examination.
Visual Examination Of Urine
Normal urine is usually clear. Cloudiness may indicate and infection. Red or
brown color may indicate blood in the urine.
Dipstick Test Of Urine

of chemical on it that react and change color upon contact with certain
substances or concentrations. A urine dipstick test checks for urine acidity,
concentration, proteins, sugars, keytones, bilirubin, infection and blood
content.
Microscopic Examination Of Urine
The patient's urine is examined under a microscope for presence and
concentration of white blood cells, red blood cells, epithelial cell, bacteria
or yeasts, proteins and crystals.
