How to understand your results

Now that you have completed your COVID-19 test and obtained the report, this interactive guide can assist you with the interpretation and help you determine the next steps.

Simply follow the process outlined below to better understand your results.

  1. To the right, select which COVID-19 Test you performed.
  2. Next, choose the option listed for the test results you received on your report.
  3. Finally, any follow up testing or additional actions that may be recommended will be indicated for your consideration.

Diagnostic Tests

PCR Testing - Overview

SARS-CoV-2 Diagnostic Salivary PCR Test

  • Diagnostic test for SARS-CoV-2, using real-time reverse transcriptase polymerase chain reaction (RT-PCR) technology
  • Detects the presence of SARS-CoV-2 viral RNA in salivary samples
  • Determines current SARS-CoV-2 infection but does not indicate past infection or immunity
  • Utilizes simple at-home salivary collection
  • No additional collection services are required
  • Rapid 24-48 hour turnaround time

SARS-CoV-2 Diagnostic Respiratory PCR Test

  • Diagnostic test for SARS-CoV-2, using real-time reverse transcriptase polymerase chain reaction (RT-PCR) technology
  • Detects the presence of SARS-CoV-2 viral RNA in respiratory samples
  • Determines current SARS-CoV-2 infection but does not indicate past infection or immunity
  • Utilizes Nasal or Nasopharyngeal swab
  • Additional collection services are required (cost is included in the price)
  • Rapid 24-48 hour turnaround time
Surveillance Tests

SARS-CoV-2 Antibody Testing - Overview

  • Not a Diagnostic Test for current SARS-CoV-2 infection
  • Detects the body's immune response to SARS-CoV-2 by measuring specific antibodies associated with the SARS-CoV-2 virus
  • Any positive results should be confirmed using the SARS-CoV-2 Respiratory PCR Test
  • Follow up testing with the SARS-CoV-2 Respiratory PCR Test should also be considered to rule out infection in individuals with a negative SARS-CoV-2 Antibody result who exhibit symptoms of SARS-CoV-2
  • Blood draw required
  • Positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E

Antibody Testing Options:

SARS-CoV-2 IgG and IgM Antibody Test

  • High-performance, semi-quantitative test
  • Detects the body's immune response to SARS-CoV-2 by measuring specific IgM and IgG antibodies associated with SARS-CoV-2
  • Expanded ability to determine current infection (IgM), as well as past infection and possible concomitant immunity (IgG)
  • 100% sensitivity and 100% specificity; no cross-reactivity with other viruses
  • Blood draw required
  • Due to an increase in demand, SARS-CoV-2 serology testing is averaging 3-4 business days to result

SARS-CoV-2 IgG Antibody Test (LabCorp)

  • Detects the body's immune response to SARS-CoV-2 by measuring specific antibodies associated with SARS-CoV-2
  • Can determine past infection and possible concomitant immunity
  • Cost-effective option, if an active infection is not a concern
  • Can be collected at over 2000 LabCorp Patient Service Centers(PSCs) across the country
  • 1-3 day turnaround time

SARS-CoV-2 Stool PCR Test

  • Not a diagnostic test for a current SARS-CoV-2 infection
  • Detects SARS-CoV-2 viral RNA in stool using real-time reverse transcriptase polymerase chain reaction (RT-PCR) technology
  • SARS-CoV-2 in the stool may be found in up to 53.4% of COVID-19 patients and can be detected in the stool for up to 5 weeks after clearance from the respiratory tract
  • Stool collection required
  • 24-hour turnaround time

Not approved or evaluated by the FDA. This test is for investigational or Research Use Only (RUO). Please note that the SARS-CoV-2 Stool Analysis is not diagnostic of COVID-19. COVID-19 can only be properly confirmed or diagnosed using a Respiratory PCR Test.
