What is the purpose of this test?

The Urine Culture, Comprehensive Test is used to detect and identify bacteria or other organisms in a urine sample that may indicate a urinary tract infection (UTI) or other urinary system-related infections. This test is crucial in diagnosing and guiding treatment for individuals experiencing symptoms such as frequent urination, painful urination, lower abdominal pain, or fever. By identifying the specific bacteria causing the infection, healthcare providers can prescribe appropriate antibiotics to effectively treat the infection and prevent complications.

The Urine Culture, Comprehensive Test includes the analysis of several analytes to provide a comprehensive assessment of the urine sample:

  • Bacteria Identification: Determines the specific type of bacteria present in the urine.
  • Colony Count: Measures the number of bacterial colonies, which helps assess the severity of the infection.
  • Antimicrobial Susceptibility Testing: Determines which antibiotics are effective against the identified bacteria, guiding antibiotic treatment.
  • Culture and Sensitivity: Identifies any growth of organisms and tests their response to antibiotics, ensuring targeted treatment.
  • Testing is conducted at >100 colonies/mL if culture results warrant, enhancing sensitivity compared to a routine Urine Culture test.

This test is essential for diagnosing UTIs and ensuring appropriate treatment, helping healthcare providers to manage infections effectively and prevent complications related to urinary tract infections.
