There are two types of coronavirus tests (COVID-19 tests) available, those that can test for a current infection (viral test) and those that can test for a past infection (antibody test).
Viral COVID testing can be done in a few different ways, the most common being nose swabs, but saliva tests are becoming more popular. Some tests are processed out on-site and can provide results in as little as 30 minutes. These are called rapid COVID tests. The majority of tests, on the other hand, are collected at the clinic on-site and then submitted to off-site labs for processing. Results can take up to 2-3 days to arrive.
Antibody testing looks for a past infection and may not reveal if you have an active COVID-19 infection because antibodies can take up to three weeks to form in your body. The presence of COVID antibodies may help to prevent you from becoming infected with the same virus again; but, because the clinical understanding of COVID-19 is still developing, it's unclear how long that protection will continue.
The CDC currently defines four instances where COVID testing is recommended:
Most COVID tests are collected by a nasal swab. A member of the medical team puts a swab inside your nose for a few seconds on each side to collect the sample. After that, the samples are packaged according to CDC guidelines and tested on-site or transported to a facility for testing. The lab will test samples for the presence of the coronavirus (SARS-CoV-2), which causes COVID infection and either your care provider or the lab will notify you with the results as soon as they are available.
Viral COVID tests are available as molecular and antigen tests. The molecular test, also known as a polymerase chain reaction (PCR) test, usually delivers results within a few days since most of these tests are sent to offsite labs for analysis. The average turnaround time for PCR test results is 48 hours, but in some instances may be significantly longer due to backlogs related to insufficient lab volume and capacity. Antigen tests are also known as rapid tests and have an average turnaround time of between 15 to 30 minutes.
Both PCR and rapid COVID tests can be used to test people exhibiting symptoms of COVID-19, those who were close contacts to COVID-19, and those without COVID-19 symptoms who live or work in a high-risk setting (such as a nursing facility); or those individuals who are identified as part of outbreak detection and response. The rapid COVID test is also recommended for the screening of residents or healthcare workers at skilled nursing facilities along with a PCR confirmation, and for repeat screening for the early detection and prevention of outbreaks in congregate settings (such as schools, workplaces, and prisons).
COVID testing is available for free under the Families First Coronavirus Response Act, which includes testing for those without health insurance. To reduce the risk of facing extra costs related to COVID testing, ask your primary care doctor to recommend a free COVID test site, and confirm there are no charges or fees for the test that are not covered by your insurance plan. Additionally, avoid getting a COVID test at a hospital or free-standing emergency room, as these facilities may charge fees for COVID testing and related services.
In many cases, COVID testing can be free. Many state and local health departments continue to offer free testing to community residents as part of their response to the pandemic. In other cases, commercially insured patients, or those on Medicare or Medicaid, may receive testing at no out of pocket cost, or with a nominal office visit copay. For cash paying patients, or those that need rapid COVID testing which will deliver results in under an hour, COVID tests can range from $50 to $150 each. It is best to call your healthcare provider prior to getting tested to better understand the cost of the specific test you require.
COVID testing is available for free under the Families First Coronavirus Response Act, which includes testing for those without health insurance. Check with your Langley-area health department as they are generally a good source for free COVID tests, or can at least point you in the right direction. Additionally, you can ask your primary care provider to recommend a free COVID test site.
COVID testing is available at many outlets near Langley including urgent care centers, retail clinics, primary care offices, health departments, and more. Different venues will have different types of tests available, many at different price points. Some testing sites are allowing walk-in patients, however, many are still requiring some degree of advance booking to control patient volume.
Rapid testing—both PCR (molecular) and antigen tests—is offered through many Langley-area urgent care centers and physician offices, usually at an additional cost ranging from $50 up to $150 per test. Usually this will allow you to get results back in under an hour, and require advanced booking through the provider. However, if you can wait 24 hours for your results, many labs are turning around send-out lab tests in that time frame, which could save you some money.
Same-day and next day appointments for COVID testing in Langley are bookable directly through Solv. Simply browse the list of healthcare providers conducting COVID tests above, find one with a “Book Online” button, and book a time that aligns with your schedule stating “COVID-19 Test” as your reason for visit.
An antibody test for COVID-19 might inform you if you previously had a coronavirus infection. Because it can take between 1–3 weeks after an infection for your body to develop these antibodies, an antibody test during an active infection would not be successful. To see if you are currently infected, you need a viral test.
Even if you have been fully vaccinated, if you have been exposed to someone who has COVID-19, experts believe that you should be tested yourself, particularly if you are experiencing cold and flu symptoms commonly aligned with the coronavirus.
Getting a COVID test is quick. Most tests are done with a nasal swab, which takes less than a minute to swab both nostrils. Depending on where you get your COVID test, this means you could be in and out of the testing site in as little as 10-15 minutes. During busy times—particularly around holidays—testing sites may be busier than usual and wait times may be longer.
Most labs are returning send-out molecular (PCR) COVID test results within 24-48 hours of the test. Some sites take longer, so call and ask if the reason for the test is proof for travel. Rapid COVID tests are processed on-site and are able to deliver results in under an hour, sometimes in as little as 15 min.
Regular COVID tests are able to detect both the Delta variant and Omicron variant in that they can determine whether or not you have the coronavirus. However, they can't tell which variation is involved. That would necessitate genomic sequencing, which is a different process from regular virus testing that not all labs can undertake. Sequencing is uncommon and can cost up to $100 per test. Since the treatment is the same for any variant, it is not clinically useful to an individual patient to know whether the infection was caused by a variant or not.
