Can someone get a false positive COVID-19 test result with BinaxNOW COVID-19 antigen test?

There is a very small chance that this test can give a positive result that is wrong (a false positive result). Your healthcare provider will work with you to determine how best to care for you based on your test result(s) along with your medical history, and your symptoms.

What tests are used to diagnose COVID-19?

Diagnostic tests can show if you currently are infected with SARS-CoV-2, the virus that causes COVID-19. There are two types of COVID-19 diagnostic tests:

Molecular tests, such as polymerase chain reaction (PCR) tests
Antigen tests, often referred to as rapid tests

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

What is the most accurate diagnostic test to detect COVID-19?

Reverse transcription polymerase chain reaction (RT-PCR)-based diagnostic tests (which detect viral nucleic acids) are considered the gold standard for detecting current SARS-CoV-2 infection.

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.

Can you get a false positive with the QuickVue COVID-19 antigen test?

There is a very small chance that this test can give a positive result that is wrong (a false positive result). Your healthcare provider will work with you to determine how best to care for you based on your test result(s) along with your medical history, and your symptoms.

What does a false-positive COVID-19 antigen test result mean?

A false-positive antigen test result means that the test says the person has COVID-19 but they are actually do not have COVID-19.

Are there any At-home COVID-19 rapid antigen tests approved by the FDA?

Authorized at-home OTC tests are available without a prescription and are typically available online or at local retailers.

Are there any COVID-19 direct antigen rapid tests recalled?

E25Bio Recalls COVID-19 Direct Antigen Rapid Tests That Are Not Authorized, Cleared, or Approved by the FDA and May Give False Results. The FDA has identified this as a Class I recall, the most serious type of recall. Use of these devices may cause serious injuries or death.

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.

How accurate are home COVID-19 tests?

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.

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.

How accurate is the Ellume COVID-19 rapid test?

Accuracy: In a U.S. clinical study, the Ellume test showed 96% accuracy for symptomatic individuals. For people without symptoms, the test correctly identified 91% of positive cases.

Is it possible to get a false positive test result for COVID-19?

It's possible to have a positive test result even if you never had any symptoms of COVID-19 . False-positive test results can occur. It may be that the test detected antibodies to a coronavirus closely related to the COVID-19 virus or that the test quality was flawed.

Can at-home COVID-19 tests give a false positive?

False positives—when someone receives a positive test result even though they are not infected—are rare occurrences. They are most likely to occur when an at-home test is not administered according to the manufacturer's instructions.

Can E25Bio COVID-19 Direct Antigen Rapid Test give false results?

As this test was not authorized, cleared, or approved by the FDA, there is not sufficient data demonstrating that the test’s performance is accurate. This means there is a risk of both false-negative and false-positive test results.

How accurate are COVID-19 PCR tests?

PCR tests are very accurate when properly performed by a health care professional, but the rapid test can miss some cases.

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.

Why do some people test positive for COVID-19 for longer?

But a growing group of people seem to be testing positive for longer. This could mean that some people may be shedding viral particles for a longer period or that the tests are picking up leftover viral debris as their infection fades, the Times reported.

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.

When should you take a COVID-19 PCR test instead of a rapid antigen test?

“PCR would be chosen where there is a low likelihood of having the virus, but we want to be certain the patient doesn't have it. Antigen would be chosen if there is a high probability the patient has the virus (i.e. is experiencing symptoms), and we need to screen the patient as positive or negative,” Heather said.

What is the difference between a molecular test and rapid antigen tests for COVID-19?

Molecular tests are generally more accurate and mostly processed in a laboratory, which takes longer; antigen tests—or “rapid tests”—are processed pretty much anywhere, including at home, in doctors' offices, or in pharmacies.
