EC scientists develop control material to help prevent coronavirus test failures

European Commission scientists have designed new control material that laboratories can use to check the correct functioning of their coronavirus tests and to avoid false negatives, the EC said on April 1.

A recent EU survey identified the lack of positive control materials as one of the top three challenges faced by laboratories for the reliable implementation of coronavirus tests.

A positive control material guarantees that laboratory tests are working correctly. It helps to avoid that a test could give a negative result if the person is positive.

The JRC-designed control material is a synthetic, non-infectious part of the virus.

As of April 1, 3000 samples of the control material are ready to be dispatched to testing laboratories across the EU.

The samples are highly concentrated and only a very small quantity of the material is required to check one test. This means that one sample tube is enough for one laboratory to check up to 20,000 tests.

Thus the 3000 samples that are now ready make it possible to check up to 60 million tests throughout the EU, the Commission said.
