Nitroprusside, Ketones (Urinary, Non-Quant.)（JIN）

The devices were distributed without required FDA premarket clearance or approval.

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; devices may cause false or inaccurate diagnostic result by lay person and lead to inappropriate medical intervention.

Deterioration in the stability of the Test Strips results in diminished low-range detection capability and inability to meet linearity performance claims. The root cause of the stability deterioration in is identified as the change in material that caused a pH shift in the coating solution resulting in precipitation during coating runs. The device defect can cause false negative results that may lead to a delay in treatment of patients with associated conditions such as diabetic ketoacidosis.

Universal Meditech Inc. was violatively distributing PrestiBio" Breastmilk Alcohol Test Strip, DiagnosUS¿ SARS-CoV-2 Antibody (IgG/IgM) Test, HealthyWiser KetoFast" Ketone Test Strips and PrestiBio" Ketone Test Strips without marketing authorization. UMI is also recall their tests because they are going out of business and would not be able to continue fulfilling any post-market responsibilities of these distributed products. UMI claims to hold 510(k)s for the other devices, purchased the intellectual property in 2015 from the previous 510(k) holder, but FDA has been unable to verify this information. The devices may have unknown performance characteristics because the firm is unable to provide any documentation that the devices were manufactured in conformance with the Quality System regulation, including documentation (e.g., DHF) that the distributed devices had not been modified since original clearance in a way that could impact their safety and effectiveness, documentation of controlled storage temperature/humidity, and post-market surveillance documentation, such as complaints and adverse events.

Product was improperly store which may cause a delay in results.

Deterioration in the stability of the reagents which has resulted in lower than expected or out of range Quality Control values.

Possible false negative or false positive results due to the product being compromised during shipment.

Three products requiring refrigerated storage conditions were incorrectly stored outside of approved temperature ranges. Using these temperature abused products may result in misdiagnosis of the patient.

Instructions sent in a letter or in instructions for use for disinfecting blood glucose and/or ketone meters were distributed but not cleared by the U.S. FDA, and devices were not cleared for multiple-patient use. Instructions could lead to inappropriate meter disinfection or improper handling of contaminated meters, which may cause infection or exacerbation of an existing infection.
