Final answer:
The method of urine sample collection is important in diagnosing a UTI as it can affect the accuracy of the diagnosis and the choice of antibiotic treatment.
Step-by-step explanation:
In diagnosing someone with UTI, it is important to know by what method the urine sample has been collected because different collection methods can affect the accuracy of the diagnosis. For example, a contaminated sample can lead to false-positive results, indicating a UTI that may not actually be present. Additionally, the method of collection can also determine the type of bacteria that are detected in the urine, which is important for determining the most effective antibiotic treatment.
