COVID-19 TESTING GUIDANCE

Evexia currently offers 3 distinct COVID-19 tests using different sample types that lend particular insights and can each contribute to a more complete picture of the SARS-CoV-2 viral progression. This interactive guide will help you determine which testing option is best for you. All testing is performed by independent, CLIA-certified high-complexity laboratories.

Follow these simple steps to find the COVID-19 testing that is right for you:

  1. Review the 3 questions to the right and click on the one that best applies to you.
  2. Continue to answer the Yes and No questions until you are supplied with the proper COVID-19 test that is is optimal for your circumstances.
  3. Click on the answer to be taken to the proper testing where you may learn more and begin ordering.
  4. We also provide this helpful testing guidance information in a convenient pdf document, click here to view or download

Available SARS-CoV-2 (COVID-19) Testing

All SARS-CoV-2 (COVID-19) tests have been validated and are performed at CLIA-Certified, High-Complexity, Laboratories.

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.
