Can A Covid Test Be Inconclusive

Who Should Test And How Often

Brevard County sees spike in âinconclusiveâ coronavirus tests

All university COVID-19 testing requirements are still in place, except for those who are fully vaccinated with a university-verified Vaccination Record Card. All faculty, staff and students will continue to have access to the on-campus COVID-19 testing program. The university encourages you to use access to this testing as an extra layer of protection.

If you are contacted by the university because you are in an area with significant increases in positive cases , everyone in that location will be required to test every other day for a period of time until cases improve.

How To Use Results Of Viral Tests

  • If you test positive, know what protective steps to take to prevent others from getting sick.
  • If you test negative, you probably were not infected at the time your sample was collected. The test result only means that you did not have COVID-19 at the time of testing. Continue to take steps to protect yourself.

How Long Does It Take To Get Test Results

RT-PCR samples are often tested in batches at sites away from where they were collected. This means it can take a day or longer to get test results.

The newly approved POC testing allows for samples to be collected and tested at the same location, resulting in quicker turnaround times.

Cepheid POC devices produce test results within 45 minutes.

In the majority of cases, RT-PCR test results are accurate. The results may not flesh out infection if tests are run too early in the disease course. The viral load may be too low to detect infection at this point.

A recent COVID-19 study found that accuracy varied, depending on when and how samples were collected.

The same study also found that chest CT scans accurately identified infection in 98 percent of cases whereas RT-PCR tests detected it correctly 71 percent of the time.

The RT-PCR may still be the most accessible test, so talk with your healthcare provider about your options if you have concerns about testing.

Sorry, but a negative test does not mean you can safely visit another household or travel for the holiday to see friends and family. A lot can go wrong between the time you took the test and the moment you hug a family member. False negatives are common with coronavirus testing whether its a laboratory P.C.R. test or a rapid antigen test because it takes time for the virus to build up to detectable levels in your body. Its also possible that you werent infected with the virus when you took the test, but you got infected while you were waiting for the results. And then consider the risk of catching the virus in an airport, on a plane or from a taxi driver or rental car agent and you may end up bringing the virus home with you for the holidays.

I dont want somebody to have a negative test and think they can go visit grandma, said Dr. Ashish Jha, dean of Brown Universitys School of Public Health.

The University Of Illinois Saliva Test

Our on-campus testing sites administer a saliva-based test, a process developed by the COVID-19 SHIELD: Target, Test, Tell team. Unlike conventional nasal testing, saliva samples are collected non-invasively, without healthcare workers and with minimal use of PPE.

The University of Illinois System received emergency use authorization from the U.S. Food and Drug Administration for the innovative saliva-based COVID-19 test.

The lab processing the samples is certified under the federal Clinical Laboratory Improvement Amendments of 1988 to perform high complexity testing.

What Does An Inconclusive Result Mean

The UW SARS-CoV-2 Real-time RT-PCR assay targets two distinct gene regions Qualitative PCR for details). When one of the two targets, but not both, is present above the threshold for positivity, the test is reported as inconclusive. This is usually seen with low amounts of viral DNA. In practice, inconclusive results should be treated as presumptive positive COVID cases with a low viral load present.

If your test sample could not be read or you got a void result, it’s not possible to say if you had coronavirus when the test was done.

What you need to do depends on the type of test you had.

There are 2 main COVID-19 tests:

  • PCR tests mainly for people with symptoms, they’re sent to a lab to be checked and you get the result within a day or two
  • rapid lateral flow tests only for people who do not have symptoms, they give a result in 30 minutes using a device similar to a pregnancy test

What Is The Rate Of Positivity For Sampling With Nasopharyngeal Vs Oropharyngeal Swabs One Swab Only Vs Two Swabs Np Swab Vs Op Vs Sputum Vs Bal

The clinical sensitivity depends on whether an individual is symptomatic or asymptomatic and the viral load present at that time. Nasopharyngeal swabs have the highest sensitivity. A study of repeat sampling in March/April, suggested that false negatives are rare among symptomatic patients . Nasopharyngeal swabs are preferred, though we accept nasal swabs and midturbinate swabs patients with a high clinical index of suspicion and a negative NP or OP swab result may benefit from sampling of the lower respiratory tract or repeat sampling.

What Should I Do If My Covid

You went through all of the trouble of getting a coronavirus disease 2019 test and you were expecting a clear answer, but unfortunately, its not always that simple. If you had an inconclusive test result, you may be wondering what you should do next. So weve broken it down for you.

If you have symptoms of COVID-19, or if youve been exposed to a person who tested positive for COVID-19, the Centers for Disease Control and Prevention recommends getting another test. This is particularly true if your first test was something called a rapid test or a rapid antigen test.

While these rapid tests are helpful when it comes to identifying a lot of cases of COVID-19, theyre not always quite as good as polymerase chain reaction tests. Thats why the CDC recommends getting a PCR test if your rapid antigen test was inconclusive, or even if it was negative but you have a known exposure or symptoms of COVID-19 .

Who Needs To Take A Day 2 Test

Everyone who arrives in England, Scotland, Northern Ireland and Wales. Tests must be booked and paid for privately. In Scotland, there is an option of paying for an NHS Covid-19 PCR Test, which costs £68.

Arrivals from green-list countries need to take a pre-departure test as well as a PCR test on or before day two of their arrival back into the UK.

However, they do not need to quarantine on return or take any additional tests.

Previously, this was unique to the green list, with anybody returning from an amber country having to quarantine for 10 days , as well as taking PCR tests on days two and eight.

However, the rules changed from 19 July, meaning travellers arriving from these destinations do not have to quarantine if they have had both doses of the Covid vaccine, or if they are under 18.

If you have been double jabbed you are also exempt from the day eight Covid test, although you must still take one on day two.

Most of the most popular countries are either on the green or amber lists, such as Spain, Portugal, Greece, Germany and France.

When You Are Fully Vaccinated And Traveling Internationally

International travelers need to pay close attention to the situation at their international destinations before traveling due to the spread of new variants and because the burden of COVID-19 varies globally.

  • Fully vaccinated travelers do not need to get tested before leaving the United States unless required by their destination.
  • Fully vaccinated air travelers coming to the United States from abroad, including U.S. citizens, are still required to have a negative SARS-CoV-2 viral test result or documentation of recovery from COVID-19 before they board a flight to the United States.
  • International travelers arriving in the United States are still recommended to get a SARS-CoV-2 viral test 3-5 days after travel regardless of vaccination status.
  • Fully vaccinated travelers do not need to self-quarantine in the United States following international travel.
  • For more information, see International Travel During COVID-19.

When To Consider Getting Tested For A Covid

If youve been exposed to the virus or show mild symptoms of COVID-19, call your doctor for advice about how and when to get tested. Dont go to your doctors office in person, as you could be contagious.

You can also access the Centers for Disease Control and Preventions to help you decide when to get tested or seek medical care.

When Do I Take A Day 2 Test

The day two test must be taken either on or before day two. The days are counted from the day after arrival. For example, if you arrive on a Friday then day one is Saturday and day two is Sunday.

You must book and pay for a day two test before you travel. Make sure you leave enough time for it to be delivered to your address in England. You can also take a day two test on arrival from an airport provider for example they are available at Heathrow and Manchester airports from £69.

You could be fined if you do not take the required test.

The test is mandatory, and must be a PCR test, regardless of how long you intend to stay in the UK.

You will need to enter the booking reference number on your passenger locator form.

Even if youve been fully vaccinated, you must self-isolate for 10 days if your day two test is positive.

What Should I Do If I Took Two Tests With Different Results

Mouth rinse and gargle COVID-19 test for school-aged children

No test is 100% accurate all the time. If you took two tests in a single day and one was positive and one was negative, its more likely that the positive test was right. Thats because the various test options are pretty accurate when they say youre positive, and slightly less accurate when they say youre negative .

While diagnostic tests like PCR and antigen tests can diagnose current COVID-19 infection, they cant tell you if youre still contagious. In general, people are most likely to transmit the virus to others in the three days before their own symptoms first appear and for about 5-14 days after. However, PCR tests can remain positive for as long as 90 days, meaning that a positive test is not always a sign that youre currently contagious .

Antigen tests, on the other hand, are usually less sensitive when it comes to identifying the virus but they tend to be positive during the window in which youre most contagious .

If you took two different types of tests and the PCR test was positive but the antigen test was negative, its a good bet that you currently have the coronavirus in your body, even if you might not currently be contagious.

If you have symptoms, the CDC recommends remaining isolated until :

  • At least 10 days have passed since your symptoms first appeared and
  • At least 24 hours with no fever without fever-reducing medication and
  • Other symptoms of COVID-19 are improving

When Is Medical Care Essential

Some people with COVID-19 feel increasingly short of breath while others breathe normally but have low oxygen readings a condition known as silent hypoxia. Both of these situations can quickly escalate to acute respiratory distress syndrome , which is a medical emergency.

Along with sudden and severe shortness of breath, people with ARDS may also have an abrupt onset of dizziness, rapid heart rate, and profuse sweating.

Below are some, but not all, of the COVID-19 emergency warning signs some of which reflect progression to ARDS:

  • shortness of breath or trouble breathing
  • persistent pain, tightness, squeezing or discomfort in your chest or upper abdomen
  • sudden confusion or problems thinking clearly
  • a bluish tint to the skin, especially on lips, nail beds, gums, or around the eyes
  • high fever that doesnt respond to normal cooling measures
  • cold hands or feet
  • a weak pulse

Get prompt medical care if you have these or other serious symptoms. Call your doctor or local hospital in advance, if you can, so they can give you instructions on what to do.

Getting urgent medical attention is especially important for anyone at higher risk for COVID-19 complications.

Older adults are most at risk of severe illness, as are people with the following chronic health conditions:

Symptoms To Watch Out For

The most common symptoms reported by people with COVID-19 include:

The symptoms of COVID-19 typically appear within 2 to 14 days after initial exposure to the virus.

Some people show few to no signs of illness during the early phase of infection but can still transmit the virus to others.

In mild cases, home care and self-quarantine measures may be all that is needed to fully recover and keep the virus from spreading to others. But some cases call for more complex medical interventions.

What Gene Targets Are Used In Each Assay

The UW SARS-CoV-2 Real-time RT-PCR assay targets two distinct regions within the N gene of SARS-CoV-2. Amplification of both targets results in a presumptive positive test result, while amplification of one of two targets results in an inconclusive result, and amplification of neither target results a negative test result. Samples with inconclusive test results should be considered as positives due to capacity constraints follow-up testing is currently not available.

The Hologic Emergency Use Authorization SARS-CoV-2 assays target two conserved regions of the of SARS-CoV-2 ORF1ab gene. The two regions are not differentiated amplification of either or both regions is a presumptive positive test result and amplification of neither target results a negative test result.

The Roche cobas Emergency Use Authorization SARS-CoV-2 Real-time RT-PCR assay targets the E gene and ORF1ab genes. Amplification of both targets results in a presumptive positive test result, while amplification of one of two targets results in an inconclusive result, and amplification of neither target results a negative test result. Samples with inconclusive test results should be considered as positives due to capacity constraints follow-up testing is currently not available.

How Do I Get A Test How Long Will It Take

Group of people from Sydney COVID

Roughly 2 million coronavirus tests are run in the United States every day. But testing availability varies considerably from state to state, even city to city. Tests are generally less available in rural areas or in communities where cases have surged and medical and laboratory resources are stretched.

The best way to find out about testing in your community is to check your local public health department website or call your doctor or a local urgent care clinic. Some cities and towns have also set up drive-in community testing sites. If your doctor or local public health clinic offers rapid testing, you usually can get the result in 15 to 30 minutes. But a positive rapid result might need to be confirmed by an additional test, especially if you dont have symptoms.

In some communities, it can still be difficult to get the results of a laboratory P.C.R. test quickly. A survey from Northeastern University and Harvard Medical School found that this fall, patients had to wait days just to schedule a test and even more time to get results. On average its been taking six or seven days after symptoms start to find out if you have the virus, and by then most people are on their way to recovery, making the test pretty useless. The research also found that Black patients, on average, had to wait almost two days longer to get results than white patients.
