Many questions remain unanswered about the test results and the differences there are between the UEFA and Serie A tests for Coronavirus.

The situations of the previous weeks were somehow open to question, as

of Inter tests announced positive in the UEFA club merely they were negative after a day.

The President of the World Association of Societies of Pathology and Laboratory Medicine elaborates that the Inter and Lazio players’ COVID tests were positive for UEFA, however, they were all reported negative in Serie A.

While Lazio have had several players including Ciro Immobile being positive in the Champions League, but  they were negative in Serie A.

 “UEFA and the FIGC ought to reach some sort of consensus,” said Professor Roberto Verna, President of the World Association of Societies of Pathology and Laboratory Medicine on TMW Radio.

“The experts ought to be consulted to agree on what viral load constitutes a positive result. The PCR test seeks out the viral nucleic acid, which is then amplified in the laboratory to make it quantifiably visible.

“It can be positive with a different viral load, and also differently infective. The antigen (antibody) test, however, is a system to find the antigens on the capsule of the virus.

“As that is a less sensitive test, which only identifies a viral load if it is fairly high, this is more important on a clinical level, as it shows us who is more infective.

“When you amplify this way, all it takes is a tiny error to amplify another aspect and the person can test positive because what was replicated is not a virus.

“In the case of COVID-19, there are three genes that originate three different proteins in the capsule. Of these, it would seem one does not show if someone is infective, but it does lead to a positive result in the UEFA test.”
