Note that several eligibility categories in MA DPH’s guidelines in both versions query public safety factors, such as the individual’s risk of disease transmission to others, rather than the probability of an individual having COVID-19. Also note how epidemiological risk factors were adjusted (removal of recent travel categories, no requirement for “close contact” with known cases, expansion of testing to essential workers besides healthcare workers). Other institution-specific testing guidelines may approach eligibility from a purely clinical view, and may have a specific set of signs, laboratory findings, and/or imaging findings needed for inpatients, or telemedicine triage protocols to assess symptoms and signs for outpatients. As testing capacity has increased, clinical sites are able to test asymptomatic individuals such as close contacts of known COVID-19 patients and people without symptoms of COVID-19 who are admitted to the hospital.
