Why do covid pcr tests take so long
The company offers other tests, such as antigen tests and slower lab-based PCR tests, at no out-of-pocket cost. Celeste Di Iorio felt fleeced after she spent a day driving from pharmacy to pharmacy in Fort Collins, Colorado, in search of a test that would give an answer in less than three days. As a musician, she had been traveling out of state and wanted to know whether she might be infectious before she attended, among other things, a memorial for a relative who died of Covid.
She and her partner eventually found rapid antigen tests at a pharmacy two cities over. In Helena, Montana, Stanfel has gotten a PCR test every week for many months because she takes immune-suppressing drugs for a rare condition called sarcoidosis. It took five days to learn that she had tested negative. It has had to prioritize tests from hospitalized or symptomatic people and send other specimens to private labs, a process that can stretch the wait time for results to up to seven days.
In New York City, where mobile-testing vans are parked in every borough and in-person home testing is offered, residents report quick turnarounds for molecular tests because the labs analyzing their samples are close by. Aspinall said flu season is likely to lead to an increase in demand for Covid testing as people with Covid-like symptoms seek answers about the causes of their illnesses, compounding staffing issues.
Antigen test. Using a long nasal swab to get a fluid sample, some antigen tests can produce results in minutes. Others may be sent to a lab for analysis. A positive antigen test result is considered accurate when instructions are carefully followed. But there's an increased chance of false-negative results — meaning it's possible to be infected with the virus but have a negative result.
Depending on the situation, the health care provider may recommend a RT-PCR test to confirm a negative antigen test result. Only a single sample is needed to check for all three viruses. This could be helpful during the flu season. But a negative result does not rule out the possibility of any of these infections.
So the testing process may include more steps, depending on symptoms, possible exposures and your provider's clinical judgment. In the U. Certain groups are considered high priority for diagnostic testing. Other people may be given priority for testing depending on local health department guidelines for monitoring COVID in individual communities.
People with no symptoms can be tested. If people without symptoms have a positive test result, they should follow guidelines for self-isolation to help curb the spread of the virus. The availability of COVID diagnostic testing and where to get tested may vary depending on where you live and the recommendations of your local public health officials.

This means that the test didn't detect the virus, even though you actually are infected with it. If you have symptoms, you risk unknowingly spreading the virus to others if you don't take proper precautions, such as wearing a face mask when appropriate. There's also a chance that a COVID rapid antigen test can produce false-positive results if you don't follow the instructions carefully. False-positive results mean the test results show an infection when actually there isn't one.
The risk of false-negative or false-positive test results depends on the type and sensitivity of the COVID diagnostic test, thoroughness of the sample collection, and accuracy of the lab analysis. They often give inaccurate results. Whether or not you have symptoms, plan to wear a face mask to and from your provider's office or the testing center.
If you have no symptoms and don't think you've been in contact with someone with COVID , but you want to get tested, ask your health care provider or testing center whether and where testing is available. Or you can call your state or local health department or visit their website for information on testing. For a COVID diagnostic test, a health care professional takes a sample of mucus from your nose or throat, or a sample of saliva.
The sample needed for diagnostic testing may be collected at your doctor's office, a health care facility or a drive-up testing center. Nose or throat swab. A long nasal swab nasopharyngeal swab is recommended, though a shorter or very short nasal swab or throat swab is acceptable. A health care professional inserts a thin, flexible stick with cotton at the tip into your nose or brushes the swab along the back of your throat to collect a sample of mucus.

Face Masks. Rather than being sent out to labs, the samples are processed on-site by a piece of equipment that can be as small as a desktop printer. Another commonly used rapid molecular test, Abbott ID Now, generates results in about 20 minutes. It seems like the best-case scenario: a highly accurate test that returns results quickly. In the case of the Fairfield hospital, it allowed a patient to get time-critical monoclonal antibodies the same day — and he responded well, Djavaherian said.
There are several reasons, Bay Area experts say — including supply constraints, cost, staffing demands, and because rapid molecular tests are hard to scale up efficiently.
The best test, experts say, depends entirely on your goal: Is it to diagnose a sick patient quickly to start treatment? To screen hundreds of asymptomatic people so they can go to work?
To get cleared to fly, go to camp or a concert? The San Francisco-based urgent and primary care network Carbon Health uses the Abbott ID Now test in its dozens of clinics, and for schools and business with whom they contract to provide frequent testing.
