A PCR Tester Has Revealed Why Your COVID Test Result Is Taking Ages.How Long Does It Take to Get COVID Results by Test Type?
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? Companion Fact Sheets. Last updated: January 18, Coronaviruses are a large family of viruses that can cause respiratory symptoms that range from mild to severe.
According to a study, about 80 percent of people who contract the new coronavirus have mild symptoms, but people over age 80 years and people with underlying health conditions are at an elevated risk for needing emergency care. Antibodies are proteins that your immune system makes after mounting a successful immune response to the virus that causes COVID Molecular tests and antigen tests are the two types of tests that can tell you if you currently have COVID Molecular tests generally take longer but are more accurate.
When taken within 5 days of the onset of your symptoms, they correctly identify a positive test more than 90 percent of the time, if done within 5 days of symptoms, according to a study. However, the effectiveness of the test in identifying the presence of the new coronavirus quickly decreases to roughly 70—71 percent between days 9 and During a PCR test, your doctor typically takes a swab of your nose and throat.
The sample is then sent to a lab for processing. Clinics that can process your results onsite may be able to provide you with your results within hours. Clinics that have to send away for results — or clinics with a backlog of tests — may take a week or more to return your results.
Rapid PCR tests are now available, although there is some concern among healthcare professionals about their accuracy. Antigen tests, also called serological tests, attempt to detect certain proteins on the surface of the virus. Antigen tests are also referred to as rapid tests because some clinics can provide you results within minutes. Since December , the Food and Drug Administration has approved over-the-counter antigen tests for home use that can provide results in less than half an hour.
Antibody tests search for a previous infection. Some clinics may be able to give you your results on the same day, while other clinics may take several days.
According to the website of the private clinic CityMD , you can expect a 3- to 5-day wait to receive your results. Many countries now require a negative PCR test within 48 or 72 hours of arrival.
Your primary care doctor may not be able to test you for COVID, but they will likely be able to recommend somewhere nearby. The Families First Coronavirus Response Act makes sure that testing is free for everybody, including people without insurance.
However, only tests performed by the CDC or a public health facility are covered. Private clinics and academic labs will bill your insurance provider. If you think that you may have COVID, you should isolate yourself at home for at least 10 days from the first day your symptoms appeared, according to CDC guidelines. If possible, try to stay in a separate room from the rest of the people in your home and use a separate bathroom if available.
Depending on which type of COVID test you get and where you get it done, you may get your results anywhere from several minutes to a week or more. PCR or molecular tests are considered the gold standard.

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. 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.

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.

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.
