OPTI Medical Systems recalls specific SARS-CoV-2 test kits due to potential false positives in RNA Master Mix vials. Affected lots may show inaccurate results.
The firm identified a precipitation issue which may cause late Ct reactors (a false positive result) with a rate of 5 to 10% for affected vials of RNA Master Mix.

The test vials can develop a precipitation issue that causes false positive results in 5-10% of cases. This means the test might incorrectly indicate a positive result when the person is not infected, leading to unnecessary anxiety or actions.
