The persistence of a positive result depends on which test was used, since the polymerase chain reaction PCR test is more sensitive than the rapid antigen tests that can be administered at home.
What Is Sensitivity? Was this page helpful? Thanks for your feedback! Sign Up. What are your concerns? This means the sample is from an infected individual. The primers only amplify genetic material from the virus, so it is unlikely a sample will be positive if viral RNA is not present.
If it does, it is called a false positive. A negative result happens when the SARS-CoV-2 primers do not match the genetic material in the sample and there is no amplification.
This means the sample did not contain any virus. A false negative result happens when a person is infected, but there is not enough viral genetic material in the sample for the PCR test to detect it. This can happen early after a person is exposed. Overall, false negative results are much more likely than false positive results.
Fact Sheet. This allows many copies of that material to be made, which can be used to detect whether or not the virus is present. A negative result could either mean that the sample did not contain any virus or that there is too little viral genetic material in the sample to be detected. What is PCR?

Place specimen in biohazard bag and seal. You may use these shipping labels for packages that are not marked with Transportation of Dangerous Goods signs. Requires completion of mandatory information for COVID testing as outlined above, along with submitter physician and patient information, and the tests requested. View a table of collection kits including: the swab or media kit image, volume, media type, intended and alternative specimen types and type of testing the kit is suitable for.
Testing for COVID does not need to be sent as STAT specimens unless the result is needed to assist health-care providers in making swift patient care decisions in an urgent or emergency circumstance. As a disease of public health significance, all positive results will be reported to the local public health unit.
Several specimen collection kits have been extensively evaluated on a number of different extraction and PCR platforms at PHO. To meet increasing submissions for COVID testing, PHO Laboratory has validated and instituted a variety of commercial assays which are validated for clinical testing. The assay used will be identified on the report. Specimens tested using the in-house laboratory developed assay will be tested using the E gene real-time PCR assay, which is more sensitive than the RdRp gene target.
This may be due to low viral target quantity in the clinical specimen approaching the limit of detection of the assay, or alternatively may represent nonspecific reactivity false signal in the specimen.
When clinically relevant, indeterminate samples should be investigated further by testing for an alternate gene target using a validated real-time PCR or nucleic acid sequencing assay at the community, hospital or reference laboratory that is equally or more sensitive than the initial assay or method used.
Some hospital and community laboratories have implemented COVID testing in-house and report final positive results, which is sufficient for case confirmation. Other hospital and community laboratories will report positives as preliminary positive during the early phases of implementation and will require confirmatory testing at PHO Laboratory. If confirmatory testing is requested, this should be indicated on the test requisition by the submitting hospital or community laboratory.
Note: Testing for other respiratory viruses and avian influenza must be ordered on the laboratory requisition if required and can be ordered on the same swab submitted for COVID testing. Recommended testing available at PHO Laboratory includes:. Note: If a person under investigation for COVID is worsening or not improving, testing should be repeated, even if previous tests were positive for another pathogen. The following data products provide access to statistics and information related to COVID to assist with surveillance and reporting.

If not for immediate transport, samples may remain in -4C conditions for no longer than 4 days before being sent to our lab for processing. We can provide upon request, but this is subject to availability of donated stock. It is the responsibility of the requesting facility to pick up any VTM they will be accepting from us. The requestor cannot use these VTM for submission of samples to another testing facility.
