La biología del SARS-CoV-2: Detección | Video HHMI BioInteractive

What does an RT-PCR test detect to confirm an active SARS-CoV-2 infection?

• Viral RNA

• Viral proteins

• Antibodies

• Host DNA

Which component of the SARS-CoV-2 virus do antigen tests identify to indicate an active infection?

• Viral RNA

• Antibodies produced by the host

• Viral proteins (antigens)

• Host cell enzymes

What information does an antibody test provide regarding a SARS-CoV-2 infection?

• Whether the virus is currently replicating in the body

• The presence of viral genetic material

• If an individual has recovered from a past infection

• The immediate severity of the illness

Why is it beneficial for healthcare professionals to use a combination of different SARS-CoV-2 tests or to repeat tests over a period of time?

• To minimize the discomfort for the patient

• To reduce the overall cost of diagnosis

• Because different tests are most effective at various stages of infection and some may produce false negative results

• To determine the patient's susceptibility to future infections
