representative for availability.What types of COVID-19 testing are available?
Molecular Testing (NAAT, RT-PCR)
• Detects the genetic material (RNA) of the virus Serology test Likely negative Likely positive
• Sensitivity varies by manufacturer, but generally very high for antibodies
Likely Likely positive Likely negative
due to amplification of the genetic material Molecular
negative
• Sample types: nasopharyngeal, anterior nasal, and oral test for virus
Likely
swabs or wash Antigen test Likely positive Likely negative
negative
for virus
• Studies suggest that RT-PCR results may be positive while
patient is not contagious1
Antigen Testing
• Detects the presence of a specific viral antigen, most RNA
commonly the nucleocapsid protein Antigen
• Sample types: nasopharyngeal, anterior nasal, and
oropharyngeal swabs SARS-CoV-2 IgG antibodies
• Results are dependent on viral load and may not correlate exposure
with NAAT/RT-PCR results2
IgM antibodies
Antibody (IgG/IgM) Testing
• Detects the presence of antibodies to SARS-CoV-2 which can
help identify people who may have previously been infected Week -2 Week -1 Week 1 Week 2 Week 3 Week 4 Week 5 Week 6
• Sample types include whole blood, serum, and plasma Before symptom After symptom onset
• May not detect a current infection as antibodies start onset
developing 1-3 weeks after infection3 Estimated time intervals and rates of viral detection are based on data from several published reports. Because of variability in values among studies,
estimated time intervals should be considered approximations and the probability of detection of SARS-CoV-2 infection is presented qualitatively.
