Final answer:
A urinalysis is the test used to identify the organism associated with a urinary tract infection by analyzing a urine sample with test strips, microscopy, and culture to detect bacteria and prescribe the correct antibiotic treatment.
Step-by-step explanation:
The test that identifies the organism associated with a urinary tract infection (UTI) is a urinalysis. During this test, a urine sample is analyzed using chemical test strips, microscopy, and potentially a urine culture if an infection is suspected.
The urine culture helps determine the presence of bacteria and the specific type of bacteria causing the infection, which is crucial for selecting the appropriate antibiotic treatment. In the context of a UTI, common pathogens include Escherichia coli and sometimes other gram-negative and gram-positive bacteria.
The presence of white blood cells in a urine test can suggest an active infection, prompting further investigation with a urine culture. After a UTI diagnosis, a physician will typically prescribe an antibiotic such as ciprofloxacin, adapting the treatment based on the results of antimicrobial susceptibility tests.
