Understanding Lab Tests for Urinary Tract Infections
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Urinary tract infections (UTIs) are bacterial infections that can affect any part of the urinary system, including the bladder, urethra, and kidneys. While UTIs often present with characteristic symptoms like burning during urination and frequent urination, laboratory testing is essential for confirming the diagnosis and guiding appropriate antibiotic treatment.
Recommended Test
Urinalysis, Complete Profile
This comprehensive urine test is the primary diagnostic tool for UTIs. It can detect the presence of occult blood, which may indicate urinary tract infections, along with other important markers such as white blood cells, bacteria, and nitrites that confirm the presence of infection in the urinary system.

Why Lab Testing is Important for UTI Diagnosis
UTI symptoms can sometimes overlap with other urinary conditions, and asymptomatic infections can occur. Laboratory analysis of urine provides objective evidence of infection by detecting bacteria, white blood cells, and other indicators of inflammation in the urinary tract.
Understanding Your Results
A complete urinalysis examines multiple components that can indicate infection, including the presence of blood cells, bacteria, and inflammatory markers. Abnormal findings help healthcare providers determine the appropriate antibiotic treatment and monitor the effectiveness of therapy.
