A unit of Abbott Laboratories is recalling two Covid-19 laboratory test kits as they can potentially issue false positive results, the U.S. Food and Drug Administration said on Oct. 14.

The U.S. Food and Drug Administration issued a new template for clinical test developers that is designed to assist these companies in developing and submitting emergency use authorization (EUA) for Covid-19 tests that can be performed at home or in other settings besides laboratories.

In a controlled laboratory test, Eagle Pharmaceuticals’ malignant hyperthermia treatment Ryanodex (dantrolene sodium) inhibited the growth of SARS-CoV-2, the virus causing the COVID-19 pandemic. The company hopes to launch a clinical trial testing the efficacy of the drug in patients.

A drug used to treat head lice in humans and parasites in animals demonstrated efficacy against COVID-19 in laboratory tests, and the U.S. Food and Drug Administration is already warning people to not attempt to self-medicate with the drug to treat the novel coronavirus.
