It also shows a normal thyroid in normal position in the lower neck. c Image taken 20 minutes after 5 mCi injected Tc99m-Pertechnetate shows normal thyroid uptake of tracer and physiological uptake in the salivary glands (short black arrow). There is a distinct focus of abnormal tracer accumulation in the left parotid/submandibular region.
For example, suppose incidence is 5%. Testing 100 people at random using a test that has a specificity of 95% would yield on average 5 people who are actually negative who would incorrectly test positive. Since 5% of the subjects actually are positive, another five would also test positive correctly, totaling 10 positive results.
COVID-19 rapid antigen tests (RATs) have been widely used for diagnosis of COVID-19. The World Health Organization (WHO) COVID-19 Case Definition states that a person with a positive RAT (also known as an antigen rapid diagnostic test or Antigen-RDT) can be considered a "confirmed case of SARS-CoV-2 infection" in two ways.
