claim: saliva-based antigen testing is less than the pcr swab
evidence_1: and, just as importantly, antigen-based testing is highly specific: unlike its pcr counterpart, the antigen test isnt fooled by faint signals of lingering viral matter outside the period of infectiousness.", "fortunately, other attributes of saliva-based antigen testing make this feasible: unlike pcr, it doesnt require trained personnel, specific chemical supplies, or centralized, expensive laboratory instrument; it is less vulnerable to the supply chain bottlenecks that plague pcr-based labs; it returns results in a matter of hours; it costs as little as $1 per test; and it could be as convenient as sucking on a piece of paper.", 
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  "rapid, saliva-based antigen testing is an essential weapon in the fight to resume many of the activities and reopen many of the venues that comprise what we used to call normal life. it is practical, convenient, cost-effective, and easily scaled.")
