The rapid detection of BV (sialidase method) was performed with sialidase investigation among the clinical laboratories. The quality control of the survey results from 2010 to 2014 with 15 different types were analyzed statistically, according to the different levels of hospital laboratories (a group of Level 2 and 3 hospitals and a group of private hospitals). From 2012 to 2014, 9 kinds of commonly used BV rapid test kits were used, and the results of different levels of hospital laboratories were analyzed.

Different levels of hospital laboratory results were consistent with the difference rate of 30.4%. In the case of using same kit, different levels of hospital laboratory results were consistent with BV difference rate of 50%.

BV results vary widely in different levels of clinical laboratories, and some clinical laboratory quality has serious problems. Strengthening the quality control and management of clinical laboratory determination for BV is important. Clinical laboratories should reduce the costs of kits and ensure the quality. For routine determination, strengthening internal quality control is one of the keys for quality control.
