The accuracy of urine bacterial culture results can be understood in several ways: 1, an accurate test report, the specimen should be perfect. If the specimen sent for testing is not perfect and accurate and is contaminated, the report given is of course inaccurate; 2. If the specimen sent for testing is a very qualified one, the results must be accurate as far as the current testing technology is concerned. Of course, the degree of accuracy requires clinicians to work together to distinguish, because some are uncommon bacteria in urinary tract infections, so the presence of these bacteria is also a challenge for the clinic, whether to see it as a colonization or a real infection. Although the results are accurate, its clinical significance needs to be observed by the physician for the specific patient.
