Sign in to monitor this recall

Summary

Changchun Wancheng Bio-Electron Co., Ltd. is recalling approximately 139,966 units of various diagnostic test strips, including UTI, ketone, ovulation, and fertility tests, because they were distributed in the U.S. without the required legal marketing clearance (510(k)). These devices were sold under multiple brand names including LotFancy, Vivoo, JNW Direct, and Urinify. Using these unvetted tests may result in false or inaccurate diagnostic results, which could lead to inappropriate medical treatments or delayed care for serious conditions.

Risk

Inaccurate results from these unapproved tests could cause a person to believe they have a medical condition they do not, or miss a condition they do have, leading to improper medical intervention or a failure to seek necessary treatment. No specific injuries have been reported to date, but the lack of FDA review means the performance and safety of these tests have not been verified.

What You Should Do

  1. Stop using the recalled diagnostic test strips immediately.
  2. Identify if your product is affected by checking the brand name and lot numbers on the packaging. Affected brands include LotFancy, PALINOIA, Vaunn Medical, JNW Direct, Urinify, The Girlfriend Doctor, URIMED, Vivoo, and Exploro. See the Affected Products section below for the full list of affected codes.
  3. Return the product to the place of purchase for a refund or replacement, throw it away, or contact your healthcare provider or Changchun Wancheng Bio-Electron Co., Ltd. for further instructions.
  4. If you have already used one of these tests and have concerns about the results, contact your healthcare provider to discuss your health status and potentially re-test using a cleared device.
  5. Call the FDA at 1-888-463-6332 (1-888-INFO-FDA) or visit www.fda.gov/medical-devices/medical-device-recalls for more information.
