FDA Explains Covid-19 Test Guidance
A 3/2 CDRH Webinar explained the FDA guidance on policy for diagnostics testing in laboratories certified to perform high complexity testing under CLIA prior to emergency use authorization (EUA) for coronavirus disease during the public health emergency. On the program, Office of Product Evaluation and Quality director of the Office of In Vitro Diagnostic and Radiologic Health Timothy Stenzel said the guidance was issued 2/29 and took effect immediately because the agency determined that with the Covid-19 public health emergency it was not feasible or appropriate to seek prior public participation.
The guidance describes a policy regarding certain laboratories immediately using tests they have developed and validated to achieve a more rapid testing capacity in the U.S., Stenzel said.
The policy is limited to laboratories certified to perform high complexity testing consistent with the requirements under the Clinical Laboratory Improvement Amendment (CLIA). It is for molecular diagnostics under the SARS-COV-2 virus. The guidance does not affect requirements under CLIA, Stenzel said, and does not affect CDC recommendations for who should be tested.
The document includes recommendations on validating newly-developed coronavirus tests before clinical use, notifying FDA when clinical use of a validated test begins, confirming the first five positive and negative samples with EUA authorized tests, indicating in test reports that the test has been validated but independent FDA review is not complete, submitting EUA within 15 days of initiating testing, and steps to take if any specimen fails confirmatory testing or if FDA is unable to authorize the EUA. It also has recommendations on the minimal testing to be performed for validation.
