#Crossing_point #False_positive
A paper reports a moral analysis of two #statistical_fairness criteria in #ML, #calibration among groups and equality of #false_positive and #false_negative rates, an issue core to the debate over group fairness definitions, but which equates with (non-)discrimination, per arXiv.
#Mount Sinai’s #prostate_cancer diagnosis #PreciseDx spinout’s #AI can also spot #Parkinson’s before #severe_symptoms. Its #algorithms found #Lewy bodies linked to the disease on nerve samples from salivary glands, outdoing humans with 1% #false_negative, #false_positive results.

„[many] reports of #false_positive test results in .. football..
In tests by another lab,
6 people from 2nd division had tested positive on Thursday,
then the club had new tests carried out by the Heidenheim Clinic -
which showed ALL 6 were negative“
2.10/x quoting
„..however, #false_results are NOT isolated.
Other labs would also have difficulties in testing..due to LACK of staff and LACK of reagents
Prominent eg’s of #false_positive tests are:
- several players from #WürzburgerKickers
&
- 3rd div’n team Türkgücü Munich.“
2.8/x quoting
„If ONLY a SINGLE-TARGET TEST is used ..,
a ⬆️⬆️⬆️ rate of #false_positive test results can be expected
than if a confirmatory test is carried out
..
A f/up check .. a lab in Augsburg revealed that 58 of 60 positives were actually #false_positives,
.. ie 96.7%.“
2.7/x quoting/translated
„These results show that the presence of HARMLESS coronaviruses can result in SUBSTANTIAL #false_positive rates
This is particularly #problematic because an #increase in infections with MORE HARMLESS coronaviruses is to be expected in CURRENT SEASON.“

„.. many potential causes of a #false_positive result .. :
> #Mislabelling at point of collection and at point of processing ..
> #Contamination during sampling and processing ..
> Low-level #reactions in PCR process, which may be generated for several reasons ..“
72/x REFERENCES
Quoting,
„The impact of #false_positive COVID-19 results in an area of LOW prevalence
False positive results..several #adverse implications..
.. false positive results are proportionally #greater in LOW #prevalence settings..“

15.1/x Coronavirus vaccine from UQ and CSL abandoned after #HIV response which scientists say was 'unexpected'
“...the vaccine generated additional antibodies that tripped up some HIV tests, leading to [HIV] #false_positive results in those tests. ..” >

Quoting/translated,
Here’s the thing:
"The results of the army [in the UK] confirm the fact that at least 90% of the PCR tests were #false_positive.
So the government is panicking over massively exaggerated and unreliable statistics."

@JennyTrigg1 Hi, you can read it here: @SabinaWalker18: 1/x ⬆️ Testing = ⬆️ Cases This ALSO: (1) ⬆️ #False_Positive PCR results (compared to True Positives)… https://t.co/aBgynRvOqV Have a good day. 🤖
If an asymptomatic person is negative before tested,
then reported as ‚case‘,
this influences everything #downstream
‚Cases‘ including #false_positives affect
#lockdown
#curfews
#False_positive ppl are unnecessarily isolated includg contact-traced
Disrupted essential services

„these results [may] #negatively impact on staffing levels & transfers in & out of home as well as causing a distraction from other elements of patient care
..adverse consequences of #false_positive results are proportionally more of an issue when #prevalence is LOW“

Of [these] 26 .., 19 were repeated and all 19 were #negative on repeat testing.“>

„If COVID was really driving admissions to hospital rather than #false_positive #misdiagnoses, then there must be cases in the community for people to catch the virus
..
Where have the missing cases gone?
The army has been called to #mass test the entire city“
4/4 quoting,
„Failure to recognize the problem of #false_positives has consequences..
#quarantining of #uninfected.
the dreaded “2nd wave” might be a surge of #false_positive tests that are inevitable in mass screenings of healthy persons“
2/x „Unlike in previous epidemics, .. WHO ..has NO requirement or recommendation for a #confirmatory test in COVID-19
..surprisingly little info on #false_positive #rate of PCR tests..
..
For all tests, the #predictive_value of a positive test #depends on #prevalence of disease“
