Please note: Question 1 and 2 on the first image have been answered. It is there for reference in order to answer the main question which is Question 3. Thank you.

QUESTION 1 The table below shows the results from looking at the diagnostic accuracy of a new rapid antigen test for COVID-19 in 100000 patients, compared to the reference standard RT-PCR test. The rows of the table represent the test result and the columns the true disease status (as confirmed by RT-PCR). COVID-19 Positive COVID-19 Negative Antigen Test Positive Antigen Test Negative 424 Antigen Test Positive 795 Antigen Test Negative Calculate the SENSITIVITY of this new rapid antigen test as percentage with 3 decimal places. (Assume that the RT-PCR reference has a 100% Sensitivity and 100% Specificity.) 34.8 QUESTION 2 The table below shows the results from looking at the diagnostic accuracy of a new rapid antigen test for COVID-19 in 50000 patients, compared to the reference standard RT-PCR test. The rows of the table represent the test result and the columns the true disease status (as confirmed by RT-PCR). 8216 90565 395 COVID-19 Positive COVID-19 Negative 924 6371 42310 Calculate the SPECIFICITY of this new rapid antigen test as percentage with 3 decimal places. (Assume that the RT-PCR reference has a 100% Sensitivity and 100% Specificity.) 86.9

Expert Solution
Step 1

Rather than identifying viral genetic material in the throat or nasal swabs, antibody tests reveal immune response indicators, such as IgM and IgG antibodies, which typically appear in the blood more than a week after symptoms begin to fade.
