Your task is to predict the verdict of a claim based on the provided question-answer pair evidence. The possible labels are: 'Supported', 'Refuted', 'Not Enough Evidence', 'Conflicting Evidence/Cherrypicking'. Justify your answer using the provided evidence and select the correct label.

Claim: COVID-19 (Polymerase chain reaction (PCR) tests are ‘scientifically meaningless’

Q1: Are COVID-19 (Polymerase chain reaction (PCR) tests accurate?
A1: a nonprofit research center in Geneva, tested five COVID-19 RT-PCR tests and found that all five achieved 100% sensitivity on positive samples, and at least 96% specificity on negative samples in a laboratory setting.

Q2: Are PCR tests accurate in real world settings?
A2: In the real world, testing conditions and process are far from perfect, and accuracy suffers. Researchers still don’t know what the real-world false positive rate is, but clinical sensitivity of RT-PCR tests ranges from 66% to 80%. That means nearly one in three infected people who are tested will receive false negative results.

Q3: Are PCR tests useful in the fight against Covid 19?
A3: Yes, because Advantages of PCR Testing
 Valuable for detecting specific pathogens that are difficult to culture in vitro or require a
long cultivation period
 Significantly more rapid in providing results compared to culturing
o Enables earlier informed decision making
o Rapid diagnosis of bacteraemia, particularly for low levels of bacteria in specimens
 Useful in detecting cases in extra pulmonary specimens which may be missed by smear
and/or culture
 Valuable screening tool
o PCR is still considered an adjunct test for certain diagnostic tests that still rely on
smear and culture, such as tuberculosis
