The Madrid Region dossier we've been commenting lately is full of proofs of appalling intentions from our gov'ts.

The sheet on universal screenings shows the LACK of test confirmation after a positive.
The protocol includes not this step, and ONE positive is noted as 'Case'

There IS redundant check for NEGATIVES, as we see in the Close Contact protocol sheet.

Antigen negative is double checked thru PCR.
It also shows that EVEN negative test have quarantine consequences.

If every PCR+ mean case, without check, it means accepting ALL FALSE POSITIVES

But the worst antiscientifical manipulation, for me, hides in the footnote

PCR is specially recommended in LOW PREVALENCE SCREENINGS

There's a purely MATHEMATICAL rational for low prevalence suffering high proportion of False Positives, plain, non "covid is new" debatable truth

With 95% values for both specificity&sensitivity and 5% prevalence in the community, up to 50% of positives are FALSE

Even though, gov recommend the flawed extremely high Ct PCR in low prevalence, instead of confirmation checks

On false+ by prevalence:

We have notice of broad gene E targeted PCR test, AND the perverse use of multiple PCR target test considering ANY positive=positive.

That opens the door to lots of false positive thru crazy high Ct levels detection of other Coronas not SARS-CoV2, provedly for E gen target test.
