Urine Culture Test

A urine culture grows whatever bacteria are present in a urine sample and counts them, which is how a real urinary tract infection is separated from a sample that merely looks suspicious. Results take a day or two, because bacteria need time to grow. Identifying the organism and testing which antibiotics kill it are usually billed as additional steps.

What it is

A dipstick or a microscope can suggest a urinary infection within minutes, but neither proves one. A culture does. A measured amount of urine is spread on a growth plate and kept warm, and whatever bacteria or yeast were in the sample multiply into visible colonies. Counting those colonies is the point: a small number can mean contamination from the skin during collection, while a heavy growth of a single organism points to a genuine infection. This code covers that quantitative culture. Naming the specific organism, and testing it against a panel of antibiotics to see which ones work, are separate laboratory steps with their own codes — which is why a single urine sample can turn into several lines on a bill.

Why it is done

  • To confirm a urinary tract infection when symptoms such as burning or frequent urination are present
  • To identify which organism is responsible, so treatment can be aimed at it rather than guessed
  • To check that an infection has actually cleared after a course of treatment
  • To sort out repeated or stubborn infections that have not responded to the first antibiotic tried

What to expect

Most samples are collected by the clean catch method, using a kit and a brief cleaning step, with the first part of the stream discarded so that skin bacteria do not contaminate the result. When a person cannot produce a sample that way, urine may be drawn through a thin catheter passed into the bladder instead. Collection is the only part the patient participates in; everything else happens in the laboratory. Growth takes time, so a preliminary answer generally comes back in 24 to 48 hours and a final one with antibiotic sensitivities can take longer. Treatment is often started before the culture is finished and adjusted once it reports.

Questions worth asking

  • Will antibiotic sensitivity testing be billed separately from the culture itself, and is it being ordered automatically?
  • Is this being run in the clinic's own laboratory or sent to an outside reference lab? The outside lab bills independently and may not be in the same network as the clinic.
  • If a urinalysis was done first and the culture was added by reflex, are both charged, and was the reflex ordered by the doctor or by a standing lab protocol?
  • Is there a collection or handling fee on top of the test itself?
