Plain-English summary
Vivoo Vaginal pH Test is being recalled by Changchun Wancheng Bio-Electron Co., Ltd.
The record states that test strips and other tests, including for near-patient testing, that require a 510(k) were distributed before they could be legally marketed to U.S. customers, and that the devices may cause a false or inaccurate diagnostic result by a lay person and lead to inappropriate medical intervention.
The record lists 3,000 units, with product names, lot numbers and expiration dates recorded in the enforcement record. The record gives distribution as US nationwide in the states of Texas, Georgia and California. The FDA has classified the action as Class II.
