Urine culture
Urine culture is a technique to detect the pathogens in your urine causing disease symptoms in the urinary tract.
When your doctor tells you they want to do a urine culture to check for pathogens or bacteria in your urine that can cause a urinary tract infection (UTI).
If you have an infection, you may feel burning when you urinate. Or, you may feel like you need to urinate, but nothing or very little comes out. Urinary urgency may also increase.
Your urinary system includes the kidneys, bladder, and the tubes that carry your urine (ureters and urethra). An infection usually begins in the bladder or kidney, affecting any part of this system. If you also have a fever or abdominal pain, you may have a more severe problem. Certain conditions can also increase your risk of a urinary tract infection, including diabetes, pregnancy, kidney stones, an enlarged prostate in men, and urinary tract surgery.
Early species identification and antimicrobial susceptibility testing of each urinary isolate may be of substantial benefit to the care of these patients. We believe that in properly collected urine samples, multiple growths often represent mixed infection and should therefore be evaluated entirely. In specific clinical settings, polymicrobial bacteriuria is not only frequently significant, but its overall clinical impact seems to be substantial. (1)
