What does my negative COVID-19 test result mean?

What does it mean? Your COVID-19 test was NEGATIVE. You most likely do not have COVID-19 at this time. You could have been exposed to COVID-19 at some point and not enough time has passed for the test to pick it up. You may test posifive at a later date.

What does it mean if I test negative for COVID-19?

A negative test result means that the virus that causes COVID-19 was not found in your sample. However, it is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID- 19. You might test negative if the sample was collected early during your infection.

You could also be exposed to COVID-19 after your sample was collected and then have become infected. In particular, people infected with COVID-19 but who have no symptoms may not shed enough virus to trigger a positive test. This means that you could possibly still have COVID-19 even though the test result is negative.

What does it mean if I have a negative rapid test result?

What does it mean if I have a negative rapid test result? A negative test result means that proteins from the virus that causes COVID-19 were not found in your sample. It is possible for this test to give a negative result that is incorrect (false negative).

What should I do if I still have symptoms after a negative COVID-19 test result?

If you use an at-home test that comes back negative, and you do have symptoms that persist or get worse, it's a good idea to get a lab-based PCR test for COVID-19 and influenza. You also should stay home and isolate until you get the PCR test results back. The antigen test may have missed an early infection.

Does a negative COVID-19 rapid antigen test mean I don't have COVID-19?

If you have a negative test, but have symptoms of COVID-19: You may have COVID-19, but tested before the virus was detectable, or you may have another illness, such as the flu.

How to Do an At-Home COVID-19 Rapid Antigen Test Correctly

How accurate are rapid COVID-19 tests?

Positive results are usually highly accurate but negative results may need to be confirmed with a PCR test. Rapid tests are most effective one to five days after symptoms start.

What does a negative COVID-19 antigen test result mean in asymptomatic persons?

Negative test results using a viral test (NAAT or antigen) in asymptomatic persons with recent known or suspected exposure suggest no current evidence of infection. These results represent a snapshot of the time around specimen collection and could change if tested again in one or more days.

How long do lingering symptoms last after COVID-19?

Symptoms. People with post-COVID conditions (or long COVID) may experience many symptoms. People with post-COVID conditions can have a wide range of symptoms that can last more than four weeks or even months after infection. Sometimes the symptoms can even go away or come back again.

How many days can the COVID-19 symptoms last?

How long do COVID symptoms last? Those with a mild case of COVID-19 usually recover in one to two weeks. For severe cases, recovery can take six weeks or more, and for some, there may be lasting symptoms with or without damage to the heart, kidneys, lungs and brain.

What are consequences of a false negative COVID-19 test?

Risks to a patient of a false negative test result include: delayed or lack of supportive treatment, lack of monitoring of infected individuals and their household or other close contacts for symptoms resulting in increased risk of spread of COVID-19 within the community, or other unintended adverse events.

How long can someone test positive on a COVID-19 rapid antigen test?

Two-plus years into the COVID-19 pandemic, scientists still arent sure how long people who catch coronavirus remain infectious, The Wall Street Journal reports. Some people keep testing positive with rapid tests beyond five days, and some even test positive after 10 days, the newspaper reported.

How long can you test positive with an at-home COVID-19 rapid-antigen-test?

At-home antigen tests may return positive results for 10 days -- or even longer, up to 14 days, according to The New York Times. Public health experts have said its been difficult to understand what that means in terms of contagiousness since rapid tests cant always predict that with accuracy.

Why PCR is better than the rapid COVID-19 test?

“PCR tests are more reliable and accurate due to testing the specific genetic material of the virus, eliminating the interference from other viruses,” said Heather Seyko, a Laboratory Services manager for OSF HealthCare.

Can a person test negative and later test positive for COVID-19?

It is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID- 19. This means that you could possibly still have COVID- 19 even though the test is negative. The amount of antigen in a sample may decrease the longer you have symptoms of infection.

When should you take a COVID-19 test after exposure?

YES: Get tested at least 5 days after exposure. Follow quarantine guidance while waiting to test.

When do you start being contagious with COVID-19?

A person with COVID-19 is considered infectious starting 2 days before they develop symptoms, or 2 days before the date of their positive test if they do not have symptoms.

How long does it take to recover from COVID-19?

Fortunately, people who have mild to moderate symptoms typically recover in a few days or weeks.

How long do most people continue to test positive for COVID-19?

According to the New York Times, the omicron variant of the coronavirus moves quickly, with viral levels typically peaking less than five days after the virus is first detectable. However, some people will continue to test positive for the virus even up to 14 days later.

Can COVID-19 symptoms get worse as it goes along?

COVID-19 can cause symptoms that are mild at first, but then become more intense over five to seven days, with worsening cough and shortness of breath.

Is it normal for COVID-19 symptoms to last more than 10 days?

People with post-COVID conditions can have a wide range of symptoms that can last more than four weeks or even months after infection. Sometimes the symptoms can even go away or come back again.

How long do body aches and muscle pains last from COVID-19?

Body aches or muscle pains may be an early symptom of COVID-19, often appearing at the very start of the illness and lasting for an average of 2-3 days. Unfortunately, COVID-19 body aches can sometimes last much longer and are commonly reported in people with long COVID-19 or post COVID-19 syndrome.

What are post-COVID conditions?

Post-COVID conditions are a wide range of new, returning, or ongoing health problems that people experience after first being infected with the virus that causes COVID-19.

Can you get a false negative COVID-19 antigen test?

The antigen level in specimens collected either before symptom onset, or late in the course of infection, may be below the tests' limit of detection, resulting in a false negative antigen test result, while a more sensitive test, such as most NAATs, may return a positive result.

Which COVID-19 tests are more accurate PCR or antigen tests?

PCR tests are more accurate than antigen tests. "PCR tests are the gold standard for detecting SARS-CoV-2," says Dr. Broadhurst. "It is the most accurate testing modality that we have.

What is the difference between COVID-19 antigen testing and molecular testing?

Antigen tests search for pieces of protein from the SARS-CoV-2 virus. The sample you provide is treated with a reagent and analyzed on the spot by a health care professional. Unlike molecular tests, these require a higher level of virus in the test sample before the test will turn positive.
