Image for representation. In this test, a swab is taken from the throat or nose of the person who is getting tested. This swab contains a small quantity of the RNA of the virus, therefore it is amplified to produce material that is enough for testing whether or not coronavirus has infected the person. To detect the same in the test, the RNA is converted into a two-strand DNA, using the process known as reverse transcription. Although this test is more accurate than a rapid antigen test, the time taken is also more.

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. On the other hand, the results of the rapid antigen test can come out in about half an hour but the accuracy is less than that of an RT PCR test.

The cost of RT PCR test in private labs has recently been reduced by the Delhi government and is now capped at Rs , if the sample is collected at the facility. However, if a technician comes to your home for sample collection, the maximum price that can be taken for the same is Rs 1,

 
 

– Why does pcr test take so long

 

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.

Why does pcr test take so long

 

Even at such hospitals, the tests are often prioritized for patients who have been admitted and staff who might have been exposed to COVID, said Chahine. His lab can process 93 samples at a time and run a few cycles a day, up to about , he said.

Last week, it did a day, three days in a row. As the worldwide demand for testing has grown, so, too, have shortages of the chemical agents used in the test kits, the swabs used to get the samples, and the protective masks and gear used by health workers taking the samples.

At the front of the line, she said, should be health care workers and first responders; older adults who have symptoms, especially those living in nursing homes or assisted living residences; and people who may have other illnesses that would be treated differently if they were infected. Bottom line: prioritizing who is tested will help speed the turnaround time for getting results to people in these circumstances and reduce their risk of spreading the illness. Still, urgent shortages of some of the chemicals needed to process the tests are hampering efforts to test health care workers , including at hospitals such as SUNY Downstate medical center in hard-hit New York.

Looking forward, companies are working on quicker tests. Indeed, the FDA in recent days has approved tests from two companies that promise results in 45 minutes or less. Those will be available only in hospitals that have special equipment to run them. One of those companies, Cepheid of Sunnyvale, California, says about 5, U. Both firms say they will ship to the hospitals soon but have given few specifics on quantity or timing.

Polymerase Chain Reaction test PCR A polymerase chain reaction PCR test is a nose and throat swab that is taken at a testing clinic and sent to a laboratory to be tested. Where can I get a PCR test? What should I do if I don’t have a private vehicle to travel to a testing clinic?

Below are some other options if you cannot travel to a testing clinic in a private vehicle. RATs are available from pharmacies, supermarkets and other retail stores. Businesses are encouraged to provide RATs to staff they wish to return to the workplace. Students and teachers are also able to access test kits through their school. Most RATs cannot be used on young children and babies. PCR testing is available for children of all ages. Where to get a rapid antigen test Individuals can purchase rapid antigen tests from most pharmacies and grocery stores.
