Understanding Lab Tests for Urinary Tract Infection (UTI)
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
A urinary tract infection (UTI) is a common bacterial infection that affects any part of the urinary system, including the bladder, urethra, ureters, or kidneys. UTIs typically cause symptoms like painful or burning urination, frequent urges to urinate, and cloudy urine. Accurate diagnosis requires laboratory testing to identify the specific bacteria causing the infection.
Recommended Test
Culture, Urine, Routine
This test is the gold standard for diagnosing UTIs by identifying and quantifying bacteria present in the urine sample. The culture can detect common UTI-causing bacteria such as E. coli and determine the specific bacterial count, confirming whether an infection is present. This test also helps healthcare providers select the most effective antibiotic treatment.

Diagnosing Urinary Tract Infections
While UTI symptoms can be distinctive, confirming the diagnosis and identifying the specific bacteria involved requires laboratory analysis. This testing is essential to ensure appropriate antibiotic treatment and to rule out other conditions that may cause similar symptoms.
Understanding UTI Symptoms
Common UTI symptoms include pain or burning during urination, frequent urges to urinate even when the bladder is nearly empty, cloudy or strong-smelling urine, and pelvic pain in women. However, symptoms alone are not sufficient for diagnosis, making laboratory testing crucial for proper treatment.
