FDA (Devices) recall action 94219
The FDA (Devices) publishes a recall like this one as 2 separate product records. They share a firm, a date and a cause; this page is all of them in one place, so the scale of the action is visible rather than spread across 2 pages.
There are two windows on the test device, the control line window and the test results window. The line for the test results window were misaligned. In instances of positive test results, the positivite test line may not be visible/ hidden under the cassette of the test device thus potentially leading to a false negative result.
The agency’s own wording, quoted from the enforcement report.
The unit total adds up the quantities the agency stated for each product. Where a product record gave no figure, or gave a weight rather than a count, it contributes nothing — so the real total is at least this, never less.
Quidel Corporation is recalling 104,300 units of InflammaDry MMP-9 diagnostic tests due to misalignment of the test results window. Positive results may be hidden and not visible, potentially leading to false negative readings.
