A contaminated urine specimen can give a large amount of false data on a dipstick test. Greater than five epithelial cells on microscopic evaluation is likely a sign of contamination.
What does possible contamination in urine mean?
If the urine is not collected in a sterile manner the urine sample may be ‘contaminated’ by bacteria that originate from the skin or genital area, and not from the urinary tract. This is often described by the clinical laboratory as ‘mixed growth bacteria’.
What does mixed contaminants in a urine culture mean?
Urine cultures that contain more than one organism are usually considered contaminated. The frequency with which such growth truly represents mixed infection is unknown. Surprisingly few studies have evaluated the clinical significance of polymicrobial growth from urine.

Why do I have UTI symptoms but no infection?

Will STD show bacteria in urine?
Urine testing is currently primarily used to detect bacterial STDs. Chlamydia and gonorrhea urine tests are widely available. Trichomoniasis urine tests are also available, but they are less common. The gold standard for diagnosing bacterial STDs, such as chlamydia and gonorrhea, used to be bacterial culture.
Does bacteria in urine always mean UTI?
Remember, bacteria in the urine does NOT equal a UTI. So, ask your clinicians if this could be asymptomatic bacteriuria. Tell them you’ve heard that the Infectious Disease Society of America, the American Geriatrics Society, and other experts say that this condition should not be treated in older adults.
Is bacteria in your urine normal?
Normal urine has no bacteria. But if bacteria get into the urethra (the tube that empties urine from the bladder to the outside) and travel into the bladder, a UTI can occur.

FAQs
How do you tell if a urine sample is contaminated? ›
Beware of Contamination
A contaminated urine specimen can give a large amount of false data on a dipstick test. Greater than five epithelial cells on microscopic evaluation is likely a sign of contamination.
If you can't hand your urine sample in within 1 hour, you should put the container in a sealed plastic bag then store it in the fridge at around 4C. Do not keep it for longer than 24 hours. The bacteria in the urine sample can multiply if it is not kept in a fridge. If this happens, it could affect the test results.
Is contaminated urine sample common? ›However, if your sample includes bacteria and natural flora from outside the urinary tract's microbiome, the waters can be muddied (so to speak), resulting in a contaminated or mixed growth sample. This is all too common. Up to 1 in 4 urine samples are considered to be contaminated.
What is the most common contaminant in urine specimens? ›The two most common sources of contamination in urine from young children are faeces and skin. E. coli and enterococci are common faecal organisms and as such would be represented highly in contaminated urines; however, E. coli is also the most common cause of UTI.
