Final answer:
The presence of bacteria in urine is a strong indicator of a urinary tract infection.
Step-by-step explanation:
The test results that most likely indicate a urinary tract infection (UTI) include the presence of bacteria in urine. A urine culture is typically performed to confirm the presence of bacteria in the urine. This is done by using blood agar and MacConkey agar to culture a clean catch of urine and minimize contamination. If a bacterial infection is confirmed, antibiotics are usually prescribed to treat the UTI.
