Urine Culture

Urine Culture & Sensitivity

A urine culture grows any bacteria present in a clean midstream sample, identifies the organism causing a urinary tract infection and tests which antibiotics will treat it.

About This Test

What the Urine Culture test tells you

A urine culture answers the question a urinalysis can only raise: is there an infection, and what is causing it? A measured amount of your urine is spread onto culture plates and incubated, and any bacteria present grow into visible colonies. The laboratory counts the colonies to judge whether the growth is significant, identifies the organism, and then exposes it to a panel of antibiotics to see which ones stop it growing. That last step, the sensitivity test, is what turns the result into a treatment plan rather than just a name.

The report is descriptive. It states whether there was no growth, mixed growth suggesting contamination, or significant growth of a named organism, usually with a colony count. Escherichia coli accounts for most straightforward urinary infections, but Klebsiella, Proteus, Enterococcus, Staphylococcus saprophyticus and others appear regularly, and each has its own pattern of antibiotic resistance. Beside the organism the report lists each antibiotic tested as sensitive, intermediate or resistant, so your doctor can choose a drug that will work rather than guess, and can switch a treatment that was started empirically if the organism turns out to be resistant to it.

Culture takes time because bacteria have to grow: a first read is possible after a day, but identification and sensitivities need further incubation, which is why results take a few days rather than hours. It is also sensitive to how the sample was taken. Skin and genital bacteria washed into the container produce mixed growth that cannot be interpreted, and a sample left warm before it reaches the laboratory lets small, harmless numbers of bacteria multiply into an apparent infection. A clean midstream sample collected before antibiotics and delivered promptly gives a result your doctor can act on with confidence.

What the culture cannot do is decide on its own whether treatment is needed. Bacteria in the urine without symptoms is common, particularly in older adults and people with catheters, and is usually left alone outside pregnancy. Your doctor reads the culture together with your symptoms, the urinalysis and your history before deciding whether, and with what, to treat.

Why Get Tested?

Confirming a suspected urinary tract infection, identifying the organism and its antibiotic sensitivities, investigating recurrent or treatment-resistant infections, and checking for infection in pregnancy or before urological procedures.

  • Names the organism

    Identifies the bacteria behind your infection instead of assuming it is the usual one.

  • Guides the antibiotic

    Sensitivity testing shows which antibiotics will work, avoiding drugs the organism resists.

  • Explains recurrence

    Shows whether repeat infections are the same organism returning or a new one each time.

  • Protects higher-risk groups

    Confirms or excludes infection in pregnancy, with a catheter, or before urological procedures.

When This Test Is Ordered

Reasons your doctor may request the Urine Culture test

Your doctor may order this test for any of the reasons below. Some are routine checks, others follow specific symptoms or an earlier result.

  • Urinary symptoms & abnormal urinalysis

    • You have burning, frequency, urgency or pain on passing urine.
    • A urinalysis showed white cells, nitrite or bacteria and the organism needs confirming.

  • Recurrent or persistent infections

    • You have had two or more urinary infections in the past year.
    • Symptoms have not settled, or have returned, after a course of antibiotics.

  • Pregnancy, procedures & complicated infection

    • You are pregnant and infection needs excluding, or you are being screened before a urological procedure.
    • You have fever with flank or back pain, or a catheter and new urinary symptoms.

Prep note
Physician reviewed

No fasting is needed.

Collect the sample before starting any antibiotic if you can, because even a single dose can stop bacteria growing in the laboratory; tell us if you have already taken one. Wash first, then collect a clean midstream sample: pass the first part of the stream into the toilet and fill the sterile container without touching the inside of it or the lid.

A first-morning sample is ideal but not essential. Keep it cool and hand it to the phlebotomist promptly, since bacteria multiply in urine left at room temperature and can turn a clean sample into a false positive.

Limitations & Safety

What this test cannot tell you

  • It is a descriptive result rather than a number: no growth, contaminated, or a named organism with its sensitivities.
  • Antibiotics taken before the sample, even one dose, can suppress growth and produce a false negative.
  • Poor collection technique or delay before the laboratory causes mixed growth or falsely high counts that cannot be interpreted.
  • Bacteria in the urine do not always need treating; the decision rests with your doctor, not the report.

Risks of the blood draw

  • Mild bruising or brief soreness where the needle went in.
  • Occasional lightheadedness, which settles after a few minutes of rest.
  • Bleeding or infection at the site, which is rare with sterile single-use equipment.
Key Points
  • 1A urine culture grows and names the bacteria causing a urinary infection, then tests which antibiotics stop it.
  • 2Significant growth of one organism points to infection; mixed growth usually means the sample was contaminated.
  • 3Collect the sample before any antibiotic if possible, since even one dose can prevent growth in the laboratory.
  • 4Results take a few days because the bacteria have to grow before they can be identified and tested.
  • 5Bacteria in the urine without symptoms is often not treated; your doctor decides using the culture and your history together.

It is better to collect the sample before the first dose, because antibiotics in the urine can stop bacteria growing on the plate and produce a false negative. If you have already started, tell us: the culture may still grow the organism, and your doctor will read a negative result with that in mind.
