Urine Culture
Also known as: Urine Culture & Sensitivity, Urine C/S
Culture is the courtroom evidence of a UTI: which germ, how much, and which antibiotic beats it. Results take 2–3 days because the lab must let the germ grow.
What this test means
A urine culture grows any bacteria present, identifies them, and tests which antibiotics work (sensitivity). It is the definitive test for urinary tract infections (UTIs).
Why it is done
It is done for burning urination, repeated UTIs, fever with urinary symptoms, and before/after treating complicated infections.
Understanding your value
Significant growth (commonly reported above 100,000 CFU/mL) suggests a true infection; the sensitivity list guides which antibiotic to use.
No growth is normal and suggests no bacterial infection — symptoms may need another explanation.
Small mixed growth often means sample contamination rather than infection — careful midstream collection avoids repeat tests.
Always treat culture-positive UTIs under a doctor's guidance, and complete the full antibiotic course to prevent resistance.
