What Does A Positive Covid Test Mean

What Do I Need To Do If I Was Exposed

What does the coronavirus test really look for? What does a positive test mean?
  • For now, we recommend that you continue to remain at home under self-quarantine until you are 10 days from your exposure. The vast majority of people who are going to become infected do so within 10 days of exposure.
  • Self-quarantine means you should stop all in-person contact with people outside your home, and not leaving your home unless for essential medical care.
  • It is important to remember that it is still possible to develop the disease up to 14 days from exposure. So if you stop quarantining at 10 days, you should still be especially careful with distancing, masking, hand-washing, and monitoring for new symptoms for the full 14 days post-exposure.

Both The Cdc & The Who Say Symptoms Are Most Transmittable At The Onset Of The Virus Even Though A Person May Not Be Showing Symptoms

After months of studying coronavirus, researchers seem to be finding that like the common cold, which is the same family of viruses as coronavirus, a person is most contagious in the early stages of having it, because the viral load is strongest then and shedding the most. Over time, the ability for a virus to infect others decreases.

Researchers have found that the amount of live virus in the nose and throat drops significantly soon after COVID-19 symptoms develop, the CDC wrote.

This information comes from more than 15 international and U.S.-based studies recently published looking at length of infection, duration of viral shed, asymptomatic spread and risk of spread among various patient groups, The CDC reported.

What Should I Look Out For

Seek medical attention if your child’s illness is worsening as described below. Persons who are placed under active monitoring should follow instructions provided by their physician or local health department.

Before seeking care, call the healthcare provider/medical facility and tell them that your child has, or is being evaluated for, COVID-19.

  • Your child is less than 2 months old and their temperature is greater than 100.4F rectally
  • Your child is crying constantly and you cannot console him or her
  • Your child is difficult to awaken
  • Your child has a stiff neck
  • Your child has purple spots on the skin
  • Your child has trouble breathing that does not improve with cleaning out the nose
  • Your child cannot swallow and is drooling
  • Your child has a seizure or convulsion
  • Your child does not urinate for more than 8 hours
  • Your child tells you something hurts
  • Your child runs a fever for more than 3 days
  • Your child develops a rash, red eyes, or significant abdominal pain
  • You have any other concerns

If you have been tested after arriving from abroad or you have been in contact with someone who has tested positive for coronavirus, avoid contact with people from at-risk groups for the next 10 days. Older people and people with a chronic illness are at greater risk of severe COVID-19. Its possible you have coronavirus and are yet to develop symptoms.

Does My Mask Protect Me If Nobody Else Is Wearing One

While its true that masks work best when everyone around you is wearing one, there is also plenty of evidence showing that masks protect the wearer, even when others around them are mask-free.

The amount of protection depends on the quality of the mask and how well it fits. Health experts recommend using an N95, KN95 or KF94 to protect yourself.

Other variables, such as how much time you are exposed to an infected person and how well a space is ventilated also will affect your risk.

I know everyone talks about planes, but I would say buses are probably the riskiest, then trains and then planes, in order of highest to lowest, said Linsey Marr of Virginia Tech, an expert in airborne transmission of viruses.

People talk about planes having great ventilation filtration, and they do and that greatly helps reduce the risk of transmission, she added. But the virus is going to be in the air, no question in my mind, because theres still large numbers of cases.

There is also real-world data supporting the protective effects of masking in other indoor locations. A 2020 investigation of a hotel outbreak in Switzerland, for instance, found that several employees and a guest who tested positive for the coronavirus were wearing only face shields those who wore masks were not infected.

And a Tennessee study found that communities with mask mandates had lower hospitalization rates than areas where masks werent required.

When To Seek Medical Attention

If you need to go to the hospital because you are having a medical emergency, call 911 or get to a hospital immediately. If you have COVID-19 symptoms that are difficult to manage, but not that serious, call your primary care provider or seek urgent care. Contact your health care provider or consider going to the emergency room if you develop severe coronavirus symptoms*, such as:

  • difficulty breathing
  • dehydration
  • fever over 102 degrees

The CDC also posts specific information about other populations who need extra precautions, such as pregnant women and racial and ethnic minority groups.

*This list is not all inclusive. Please consult with your medical provider for any symptoms that are severe or concerning.

Amplification Of Either Or Both Regions Is A Presumptive Positive Test Result And Amplification Of Neither Target Results A Negative Test Result

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. There was a problem with the sample you provided or the test itself.

How Likely Is A False Positive From A Lateral Flow Test

What Does Positive Coronavirus Test Mean for President and First Lady? | NBC10 Philadelphia

A study published in the Clinical Epidemiology journal in October 2021, conducted by researchers from the University College London, Liverpool University, Harvard University and the University of Bath, found that lateral flow tests are more than 80 per cent effective at identifying positive Covid-19 cases.

And the study found the tests are more than 90 per cent effective at detecting the virus when someone is at their most infectious.

UK-based GP Dr Gary Bartlett told The Independent: What I often tell my patients is that lateral flow tests are really useful for asymptomatic screening .

If you have symptoms suggestive of Covid then you must get a PCR test which are the gold standard test for Covid as they are better at detecting Covid. If you have Covid symptoms, lateral flows are less reliable as they can be associated with false negatives, often leading the person to believe that they dont have Covid when in fact they do.

He added that false positives a test showing you have Covid when in fact you do not are extremely rare, and only happen in a fraction of a per cent of occasions.

Professor Adam Finn, a member of the UKs Joint Committee on Vaccination and Immunisation told the British Medical Journal: If come up positive that means you are potentially infectious to others and must self-isolate. They are not green light tests: you cannot be sure that if the test is negative you are not infectious, and you must continue to take the usual precautions.

What If The Line Is Faint

Even if the line next to the T is extremely faint, that still means your test is positive.

Government guidance states: Result lines may appear smudged or faint, but they are still valid results and must be reported.

However, you should be careful to read the instructions for your lateral flow tests before taking them, as sometimes they can show false positives if you read them too late.

The instructions will tell you how long to wait before checking your test. Most say between 15-30 minutes.

NHS A& E doctor Nathan Hudson-Peacock has said a second line which appears after the 30-minute window may not indicate a positive result.

He said : If the faint line appears after the window, the most likely cause is either that there has been some contamination or there are just very low levels of the virus.

If it is the latter, and obviously assuming you are asymptomatic at this point, then you are unlikely to be a transmission risk.

He added that a sensible approach would be to be extra careful with precautions and to continue with lateral flow tests in accordance with NHS guidance.

How Do Lateral Flow Tests Work

To take an antigen test, you take a swab from inside your nostril, the back of your throat, or both, depending on the specific test you are using.

You then mix that swab with solution and drip it onto a device which contains a test strip.

The test strip has antibodies specific to the Covid-19 virus painted on it in a thin line.

These antibodies will bind to any antigen in the sample. If the testing strip detects the virus, it will show up as a thin red line next to the T on the device.

Caring For Your Child With Covid

If your child has been diagnosed with a viral infection , antibiotic treatment will not cure the viral infection. If given when not needed, antibiotics can be harmful. The treatments described below will help your child feel better and help the body’s own defenses fight the virus:

  • Drink a lot of water
  • Use cool mist vaporizer or saline drops or nasal spray to relieve congestion
  • Ibuprofen or acetaminophen for discomfort with fever or aches and pains

Shouldnt You Just Be Positive Or Negative

Tested positive for Covid

PCR tests are used to detect a range of viruses and pathogens. They look for viral genetic material in a respiratory sample, such as a nose or throat swab or a saliva sample.

We identify a sample to be positive or negative based on the number of times we need to amplify the small segments of genetic material to detect the virus and whether this number falls below or above a certain threshold.

When theres a lot of virus present, we only need a few cycles of amplification to detect it. When there isnt much virus, or theres none, we need to amplify the sample several more times until finally we cross the threshold and deem the sample negative.

Read more:The new 15-minute test has potential, but standard tests are still the best way to track COVID-19

So in this process we can see the potential for a weak positive result. It would generally be a reading at or just above the threshold. And that threshold varies depending on the test used.

Importantly, thresholds are just the point at which we believe weve detected something. Theyre not 100% precise. Sometimes results just above or below the threshold might be false negatives or false positives.

Neither Pcr Nor Rapid Tests Directly Measure Contagiousness But They Both Shed Light On Whats Going On Inside You The Key Is To Understand What They Can And Cannot Tell You


Rapid tests detect specific proteins inside the SARS-CoV-2 virus, and only light up when there is a ton of it on your swab, to the tune of millions of copies. Thus, a positive rapid test means that your swab is teeming with virus, and you are likely contagious.

A negative rapid test is trickier to interpret. In the early days of an Omicron infection, you can be contagious yet test negative, because the virus hasnt taken off *yet* in your nose. In the later days of infection, a change from positive to negative sends a strong message that youve cleared the virus.

How long will I be positive? With rapid antigen tests, people only test positive during the infectious period of 1-2 weeks. A recent study of NBA players tested daily found high viral levels for an average of 10 days with Omicron, and 11 days for the Delta variant, with significant person-to-person variation.

PCR can detect whispers of residual virus, long after the contagious period. Think of PCR as a sleuth checking out the scene of the crime to see if there is any lingering evidence of a villain. Thus, a positive PCR test doesnt tell you whether youre teeming with virus, or cleaning up the last little remnants. Your contagiousness depends on where you are in this journey.

How long will I be positive? With PCR, you can expect to test positive for weeks, or even months , well after the infectious period.

This could result in pcr positive but it does not mean that the virous is virulent or infectious, rather it means that residues and non active viral rna is still detectable by pcr. They give a value, called a ct or cycle threshold value, that indicates many amplification cycles it took to get a strong signal. Its possible that you had the virus, but that:

When Is The Best Time To Take The Covid

Because it takes time for the immune system to develop the IgG antibodies, the blood test cant be done too early. Studies tell us that over 90% of people who have had COVID-19 will have produced the IgG antibody 14 days from the start of the illness.

So the best time to take the COVID-19 IgG antibody blood test is 1421 days after you first become unwell. How long the IgG antibody will continue to be detected in the blood isnt yet fully known because the virus hasnt been around for long enough.

A Guide To Recovery At Home For Patients And Their Families

Dr. Zorba Paster clarifies the meaning of COVID-19 test results

If youve tested positive for COVID-19, you may be worried for yourself and others with whom you’ve recently spent time. Below are steps to ensure you have the best chance for recovery and to help reduce your chance of infecting others.

With a confirmed positive COVID-19 test, you are most likely being sent home to rest, stay away from others, and recover. This is the case for more than 95% of people, as their symptoms do not require hospitalization. Some people have a higher risk for complications and should be monitored extra closely. For most people, COVID-19 symptoms tend to go away naturally as the body works to recover from infection.

What Does A Positive Lateral Flow Test Look Like

Lateral flow devices are small white rectangles made of plastic with a testing strip inside.

There is a small well at the bottom of the device with the letter S next to it. This is where you drop your sample.

Above this there is a window to the testing strip. Towards the top of the window is the letter C, and below it is the letter T.

The C stands for control and the T stands for test.

Once you have dropped your sample into the well, a red line should appear next to the C relatively quickly. This line should be present every time you do a lateral flow test.

If a red line appears next to the T that means you have tested positive. If there is no line, that means you have tested negative.

What Happens If I Have No Symptoms By 14 Days From My Exposure

If you self-quarantine for 14 days after your last exposure to someone diagnosed with COVID-19, and have developed no new or worsening symptoms, then you likely were not exposed enough to cause an infection. At that point, you can confirm with your local department of public health and/or your healthcare provider that you can come out of quarantine.
