In general, microbiological diagnostic procedures in the practitioner's office are limited to direct detection of group A streptococci in throat swabs in patients with pharyngitis and to semiquantitative urine culture with Uricult or Urotube test kits in patients in whom urinary tract infection is suspected. Negative direct tests with throat swabs should be confirmed by culture in the clinical microbiology laboratory, as several test kits have only moderate sensitivity in detecting group-A beta-hemolytic streptococci and do not detect other groups of beta-hemolytic streptococci. The results of semiquantitative urine cultures should always be interpreted together with clinical data. Quality control procedures are necessary for the accurate performance of these tests, and an external quality assessment program will probably be introduced in the near future.
一般来说，从业者办公室的微生物诊断程序仅限于对咽炎患者的咽拭子进行A组链球菌的直接检测，以及对疑似尿路感染患者使用Uricult或Urotube检测试剂盒进行半定量尿培养。咽拭子直接检测结果为阴性时，应在临床微生物实验室进行培养以确认，因为一些检测试剂盒在检测A组β溶血性链球菌时灵敏度仅为中等，且无法检测其他组的β溶血性链球菌。半定量尿培养结果应始终结合临床数据进行解读。为准确进行这些检测，质量控制程序是必要的，并且在不久的将来可能会引入外部质量评估计划。
