– Why does the pcr test take so long
Find out how long it takes to get your NHS test result for COVID If you did a PCR test from the NHS, you might get your result the next day. Antigen test: This detects bits of proteins on the surface of the virus called antigens. Antigen tests typically take only 15 to 30 minutes. › › Coronavirus › News.

If you did an NHS rapid lateral flow test, you should report the result of a home test as soon as possible. Find out about how to report your NHS test result.

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. 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.
Other test kit makers and labs are also ramping up capacity. Smaller labs — such as molecular labs at some hospitals — can do far fewer per day but get results to patients faster because they save on transit time. 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.
