Portuguese Court of Appeal considers PCR tests unreliable and lifts quarantine
Here the judgment can be found. Due to lack of language skills, reference is made to the presentation and interpretation of the judgment on tkp.at , where the tenor is quoted as follows:
” Based on the currently available scientific evidence, this test is [the RT-PCR test] in and of itself is not able to unambiguously determine whether the positivity actually corresponds to an infection with the SARS-CoV-2 virus, for several reasons, two of which are paramount: the reliability of the test depends on the number of cycles used; the reliability of the test depends on the viral load present.
With reference to Jaafar et al. (2020; https://doi.org/10.1093/cid/ciaa1491) the court concludes that “if a person tests positive by PCR, if a threshold of 35 cycles or higher is used (as described in most laboratories in Europe and the US), the likelihood that this person is infected is <3% and the likelihood that the result will be a false positive is 97% “. The court also notes that the cycle threshold used for the PCR tests currently being carried out in Portugal is unknown.
With reference to Surkova et al. (2020; https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30453–7/fulltext ) the court further states that every diagnostic test must be interpreted in the context of the actual probability of illness, as assessed prior to performing the test itself, and expresses the opinion that “In the current epidemiological landscape, the likelihood of Covid-19 tests giving false positive results is increasing, with significant implications for individuals, the health system and society Has”.
The court’s summary for ruling against the regional health authority’s appeal reads as follows:
