The amount of time it takes to get the results of your COVID test depends on what type of test you get and which clinic you go to. You may get your results within minutes, or it may take a few days. Many clinics are experiencing backlogs that have led to delays in test results by a week or more. 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. Antigen tests are generally quicker but have a higher chance of giving false-negative results.

Sputum: collect if patient has a productive cough. Do not induce. Use of laboratory testing for clearance of confirmed and probable COVID cases from isolation For each scenario below, cessation of isolation requires that the individual is afebrile and symptoms are improving. For confirmed and probable cases at home: Laboratory testing is not required for discharge from isolation. For hospitalized patients: Isolate in hospital until two negative tests, obtained at least 24 hours apart.
If discharged home within 14 days of symptom onset, follow advice for individuals at home. Requisitions and Kit Ordering.
Laboratory Testing COVID PCR Collection Kits View a table of collection kits including: the swab or media kit image, volume, media type, intended and alternative specimen types and type of testing the kit is suitable for. Failure to ship COVID specimens separately may delay testing, primarily due to delays in transportation. Specimen may inadvertently be processed as a routine sample. Test Methods. Specimens with no gene target s detected in the assay used will be reported as COVID virus not detected.
Additional testing will include real-time PCR on an alternate assay see table above. Subsequent detection of COVID virus by any single gene target with a validated real-time PCR assay, or alternatively by the RdRp gene sequencing assay, is sufficient for laboratory confirmation. Specimens will be sent to NML for further testing if required.
This could be for various reasons, most commonly due to failed detection of assay control. Each invalid result is accompanied with a specific comment to explain the cause.
Case Confirmation Some hospital and community laboratories have implemented COVID testing in-house and report final positive results, which is sufficient for case confirmation.
Testing for avian influenza can be ordered if patients meet criteria for this testing. Legionella urinary antigen testing minimum urine volume 2 ml. Data and Analysis. Updated 16 Nov Share to. Copy link URL:. These tests detect viral proteins, or antigens, in a sample taken using a nasal swab.
Inaccurate results come in two types: Either the test wrongly suggests that someone who is infected with SARS-CoV-2 is virus-free known as a false negative , or the test wrongly suggests that someone who is actually uninfected is carrying the virus known as a false positive. The test is faster, cheaper and easier to run than the gold-standard PCR test.
Most of the at-home coronavirus testing kits given emergency use authorization by the FDA are rapid antigen tests. However, results from rapid antigen tests are less reliable. If the antibodies flow all the way down even in the presence of viral proteins, or get snagged in both lines even when there are no viral proteins to bind, the test can return an inaccurate result.
If this test returns a negative result for someone with symptoms of COVID, a health care provider may order a more accurate molecular test. This type of test uses a blood sample to detect specific immune proteins known as antibodies. These are found in the serum, the clear liquid that remains when clotting proteins and cells have been removed from blood. Our bodies make antibodies in response to infections, including coronaviruses.
While we produce antibodies to coronavirus during infection, antibodies to viruses also linger long after the infection has passed, which makes serology tests poor indicators of active infection. Additionally, most serology tests are designed detect a type of antibody that arises later during an infection, making them better at showing prior exposure. These tests are not yet available in clinical settings. Scientists are currently studying the question of how well antibody levels — whether after infection or vaccination — correlate with protection against infection or reinfection by SARS-CoV Several kinds of tests, including those that use technology similar to pregnancy tests, have hit the market become available , though not all give reliable results.

This Fred Hutch research project is enrolling volunteers who are at high risk of being exposed to the coronavirus including health care workers, employees of long-term care facilities and hospitals, first responders, grocery store employees and bus drivers.
More than 30 U. Individuals are needed to help us learn more about how the virus affects the immune system. Volunteers will be paid to perform weekly home testing for COVID and complete symptom questionnaires. Donate Now. Demystifying Coronavirus Tests Coronavirus tests are making headlines, but confusion remains. Depending on the test, the swab may be sent to a lab for analysis, or analyzed where it was collected. IA tests occur at a steady temperature. Fluorescent dye molecules bind the virus DNA as it is copied, making the sample glow.
If the sample contains viral DNA, the millions of fluorescent bits of viral DNA allows the sample to reach a threshold of fluorescence, leading to a positive result. A patient is tested for coronavirus in late April, Testing for Infection: Rapid Antigen Test These tests detect viral proteins, or antigens, in a sample taken using a nasal swab. The sample is placed on a paper strip on which there are three lines of antibodies, specialized immune proteins that bind other proteins, also known as antigens.
The first line is made up of antibodies that bind a certain SARS-CoV-2 protein the antigen in question and are attached to a detector molecule. The second line is made up of similar antibodies that are firmly attached to the paper strip. As the viral proteins flow down the strip, they are bound by the detector antibodies, and this complex flows into the first antibody line — the anti-SARS-CoV-2 antibodies. A positive test, suggesting the presence of viral proteins, shows up as two colored lines because the detector molecule is present in both lines of antibodies.
If there are no viral proteins, then no complexes get snagged by the first line of antibodies, and the detector antibodies all continue flowing down to the line of control antibodies. A negative result shows up as one line.
A medical worker demonstrates the administration of a rapid antigen test for air passengers in Munich, Germany. A blood sample is taken, then sent to the testing lab. What happens when you get a PCR test You may have your temperature checked when you arrive. You need to wear a mask at the clinic and remove it to provide a sample. A doctor or nurse will ask if you have any symptoms. The swab is then sent to a laboratory for analysis. The test is safe, free and you do not need a Medicare card.
A PCR test is usually a bit uncomfortable but not painful. Do not stop off along the way. If you need to pick up your children, ask another parent or family member to drop them home.
You cannot leave your home unless it is to seek medical care or because of an emergency. You cannot have visitors. Monitor how you feel. If symptoms become serious such as shortness of breath while sitting or difficulty breathing , call Triple Zero Ambulance services are provided free of charge to people who are suspected or confirmed COVID cases. If you share a home with other people separate yourself from them as much as possible when you are at home with others, spend time in separate rooms if you can wear a face mask when you are in the same room as another person and keep 1.
