When coliform organisms are found in urine what does it mean?

Coliform bacteria: The first possibility is that it is a "dirty sample" meaning that bacterial contamination took place and it was not a clean catch urine. In the event that it was clean, the presence of bacteria along with other markers, symptoms, and so forth would give a better picture. The presence of wbcs, leukocyte esterase, and nitrites are common in urinary tract infections. So more info is needed.

It depends: it is not unusual for bacteria to be in urine.....it is only a problem if it causing symptoms, such as pain with urination, increased frequency of urination or urgency to urinate. if you have a urine culture that shows bacteria and you have no symptoms, the current recommendation is not to treat that. overuse of antibiotics cause bacterial resistance, which is a huge problem.
