How COVID testing works | NSW Government.
New COVID restrictions for international travel and other activities are fueling consumer demand for highly accurate polymerase chain reaction, or PCR, tests with rapid turnaround times. Some clinics can deliver a PCR test result within hours, which these days can be as essential as a plane ticket for air travel. The downside? It will likely cost you hundreds of dollars. The molecular-based tests, considered the gold standard for detecting COVID , are a reliable tool but can take days to process, particularly as cases of the virus surge and people queue up for testing.
Unlike less accurate antigen tests , which can be used at the point of care and deliver results within minutes, PCR tests typically require the use of lab equipment as well as technicians who are trained to process and interpret the results.
Clinics with their own onsite labs can process results more quickly. COVID testing has spawned a veritable cottage industry, with medically minded entrepreneurs stepping up to meet increased demand — often charging top dollar to expedite PCR test results. Such services are undeniably convenient for those who can afford them. Yet they also underscore the ongoing constraints in COVID testing , which experts say is unfair for people of more modest means, and reflects wide gaps in insurance coverage for what's becoming a necessary tool for many people.
Clear19 Rapid Testing, founded in March in an effort to contain the virus before vaccines became available, offers the speedier molecular-based testing services for a premium. Clear19 uses a robotic lab that can process 90, specimens overnight, delivering test results to patients within 24 hours. That's why we can guarantee overnight results," said Sandy Walia, founder and director of Clear The company also offers same-day testing, which Walia called "the private jet of testing.
The price for a rush test result? Molecular tests are more sensitive than rapid antigen or lateral flow tests, meaning they detect the virus, including the Omicron variant , early and before an individual is contagious in some cases. They are gentle and non-invasive, meaning patients are no longer required to practically have their brains tickled with a long, thin nasal swab.
Walia expects that current strict testing requirements for travel, which vary by country, will eventually loosen, and demand for overnight and faster results will recede. But testing will remain crucial for preventing the global spread of new variants. But if this thing is still around for a little while, testing will be the only way to prevent global spread," she said.
Sameday Health, another testing outfit started during the pandemic, has also sought to expedite the turnaround time for COVID tests. Emad, who says the self-funded company is already profitable, thinks demand for PCR testing will hold steady as cases of the virus remain elevated.
It seems Omicron doesn't care if you're fully vaccinated or have the booster, we are still seeing breakthrough cases in people who have their triple shot, and we are here if we are needed," he said. Experts say U. Most insurance providers cover basic PCR testing services that deliver results in 48 hours, but that have proven inadequate for people who need their results faster than two days. Depending on the clinic and patient's insurance plan, a portion of the cost of the rush test may also be covered.
Earlier this month, as part of its winter plan to battle COVID, the White House said it would require insurers to reimburse Americans for the cost of over-the-counter at-home tests, in addition to those that are administered at the point of care.
In New York, medical provider CityMD is advertising three- to five-day turnaround times for PCR tests, the costs of which are fully covered by most insurers, according to the drop-in health services provider. A five-day old test result is useless for someone who is en route to Canada, for example, which requires proof of a negative PCR test administered within 72 hours of takeoff.
One reason for the widespread delay in delivering results likely has to do with staffing challenges , experts said. There needs to a broad strategic plan to monitor and ensure access to all types of testing and quick turnaround times. Long delays can also make a test less useful if an individual has the virus and doesn't know she is infected.
That's where the inequality could be further exacerbated by this," Columbia University's Chan said. Omicron variant sparks new safety measures. Please enter email address to continue. Please enter valid email address to continue.

Those testing positive on a lateral flow are now required to isolate for five full days, and can leave quarantine on day six after negative tests on day five and six. If you've got symptoms of the virus, you can get a test and there are 12 other reasons that you can still access a follow up PCR. The NHS says you can get a free PCR test if you have a new persistent cough , a high temperature or a loss of taste or smell. You can also do a lateral flow test at home which takes just 30 minutes and due to Omicron cases being high across the UK, people are urged to just take these.
While Omicron cases remain high, they are falling and most people who catch the bug say they have cold-like symptoms. A string of hugely positive studies show Omicron IS milder than other Covid strains, with the first official UK report revealing the risk of hospitalisation is 50 to 70 per cent lower than with Delta.
Covid booster jabs protect against Omicron and offer the best chance to get through the pandemic , health officials have repeatedly said. The Sun's Jabs Army campaign is helping get the vital extra vaccines in Brits' arms to ward off the need for any new restrictions. PCR polymerase chain reaction tests are the gold standard and are sent off to a lab to be properly processed - unlike lateral flow tests that can be completed at home in less than an hour.
It is sent to a laboratory where a lab technician looks for genetic material of the virus using highly specialised equipment. The PCR tests are much better at finding very small amounts of the virus, especially early during an infection. So these are used primarily in people who have Covid symptoms.
A PCR test is also known as a molecular test. This test is performed using a nasal swab inserted and rotated into one or both nostrils for sample collection. After the patient-testing portion is completed, your nasal swab is analyzed in a laboratory to determine whether COVID molecular material is present in your system. In most instances, patients receive the results of their PCR tests between 3 and 5 days after testing.
Some are provided in as little as 24 hours. Results will never take longer than a week. The test can be completed in four to eight hours, however, the results are available in one day due to time taken in collection and in the transportation of samples to the labs. This also adds to the time taken by labs to conduct this test. If the testing lab is far from the place where the sample of the person has been collected, the test result may be available after 48 hours or more, in some cases.
