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.

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.

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

Rapid antigen tests: What does it mean if result is positive after 5 days? | FOX 7 Austin

Can you still test positive after recovering from COVID-19?

According to the Centers for Disease Control and Prevention, some people who contract COVID-19 can have detectable virus for up to three months, but that doesn't mean they are contagious. When it comes to testing, however, the PCR tests are more likely to continue picking up the virus following infection.

What is the recovery time for the coronavirus disease?

Early research suggested that it could take 2 weeks for your body to get over a mild illness, or up to 6 weeks for severe or critical cases. Newer data show that recovery varies for different people, depending on things like your age and overall health.

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 is the accuracy of the COVID-19 antigen test?

If possible, taking an at-home rapid COVID-19 test the day of the event is ideal. While these tests aren't 100% accurate, a negative result strongly suggests that you're not contagious at that particular time.

What does a positive COVID-19 antigen test result mean in a person with no symptoms?

When testing an asymptomatic person in a community setting for COVID-19, the healthcare provider generally can interpret a positive antigen test to indicate that the person is infected with SARS-CoV-2; this person should follow CDC's guidance for isolation.

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.

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.

Should I repeat the at-home COVID-19 test if it is negative?

Some self-tests are designed to be used in a series (also known as serial testing). Consider repeating the test 24 to 48 hours later. Multiple negative tests increases the confidence that you are not infected with the virus that causes COVID-19.

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.

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.

How long does it take for antibodies to develop after exposure to COVID-19?

It can take days to weeks after an infection for your body to make antibodies.

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 can cause a false positive COVID-19 rapid antigen test?

The investigators also point out that false-positives are possible due to administering the test too early or late in the infectious stage, or from incorrectly performing the self-test.

Even though demand for COVID-19 tests greatly overwhelmed supply earlier in the pandemic, rapid home tests are more available today. While home tests provide a quick, accurate result, the flip side is that many test results are no longer reported to health authorities.

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.

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).
