Additionally, A new test was also developed to help screen for
the new disease quicker. The gold standard test was the PCR test
and was used to confirm if the new rapid screening test was
accurate. When the new screening test was used it found that 22
people had a positive result and 55 had a negative result. Of the
22 who were positive on the screener the confirmatory PCR test
found that 20 of them were true positives. Of the 55 who were
negative on the screener 43 of them were confirmed to be true
negatives on the confirmatory PCR test.
