Positive results: What now

You do not need to perform repeat testing. Consult a healthcare professional and tell them that you tested positive for COVID-19. Provide your healthcare professional with:

There are a few immediate steps you should take.

  1. You do not need to perform repeat testing.
  2. Consult a healthcare professional and tell them that you tested positive for COVID-19. Provide your healthcare professional with:
    1. Your Test Result Record (sent to you via email, if selected, and in your COVID-19 Home Test app)
    2. The Product Overview for Healthcare Professionals
    3. The Fact Sheet for Healthcare Professionals
    If you have no symptoms, your healthcare professional may recommend a confirmatory test. Please see FAQ ‘Can I have a false positive test result?’
  3. You should self-isolate at home as per CDC recommendations to stop spreading the virus to others.
    Please consult the CDC recommendations regarding self-isolation:
  4. If you are in a high risk group it is very important to see your Healthcare Professional as there may be treatment options available to you. Further information can be found at or

    There is a very small chance that this test can give a positive result that is wrong (a false positive result) especially if you use the test when there are very few COVID-19 infections in your local community. Your healthcare provider may suggest you need molecular testing to confirm whether you have contracted the virus causing COVID-19. Visit FAQ ‘Can I have a false positive result’ on our website.

High Risk Groups:

We recommend you check if you are at high-risk from COVID-19. You can find a list of high-risk patients on the CDC website. If you are a high-risk patient, we recommend you contact your Healthcare Professional and advise them you have tested positive for COVID-19 with a Rapid Antigen Test.

Internal Quality Control:

Our test utilizes a sample quality control, which other OTC antigen home tests do not have. This control detects if you have swabbed effectively to protect you against dangerous false negative results.

A false negative is when a user receives a negative result but is positive for COVID-19. With other OTC antigen home tests, a false negative could happen when a user does not swab themselves properly (or at all), but their test is unable to identify the sample isn’t sufficient to generate an accurate result.

A false negative result due to ineffective sampling increases the risk of that user spreading COVID-19 to their family and community.

Negative result: What now

Have you received a negative result?

A negative test result indicates that antigens from the virus that causes COVID-19 were not detected in your sample. However, if you have symptoms of COVID-19, and your first test is negative, you should test again in 48 hours since antigen tests are not as sensitive as molecular tests. If you do not have symptoms and received a negative result, you should test at least two more times with 48 hours in between tests for a total of three tests. If you have a negative result, it does not rule out SARS-CoV-2 infection; you may still be infected and you may still infect others. It is important that you work with your healthcare provider to help you understand the next steps you should take.

Errors & insufficient swab result: What now

We are sorry if you have received an error with our test.

Unlike some other OTC antigen home tests, our test presents an Error message when there was a problem, and it was unable to provide you an accurate result – rather than risk giving you a false or inaccurate result.

Errors occur either due to a technical issue with the test (such as damaged components, connection difficulties or low battery power) or if the swab sample did not have sufficient sample to generate a reliable result.

With any error, please contact our Customer Support team on 1-888-885-6121 and provide them the details of your error so we can determine the best solution for you.

Technical Errors:

In the case of a technical error, contact Customer Support so we can organize a replacement. These errors are extremely rare and we apologize for any inconvenience caused.

Error 20 / Insufficient Swabbing:

We’re sorry if you have received an error 20 message, but we’re also very proud of our error 20s. We appreciate they are frustrating and may have caused you concern or disrupted plans, but they’re extremely important when it comes to testing individuals for COVID-19.

Unlike other OTC COVID-19 antigen home tests, our test is smart enough to detect when there is insufficient sample.

Just as if a doctor was taking your test, if they felt they didn’t get sufficient sample, they would take another swab. That’s the same with our test.

With other OTC COVID-19 antigen home tests, users can swab themselves poorly, or not at all, and the test will return a negative result. That’s because those tests do not have the technology in place to check the sample they are testing. This can lead to ‘False Negative’ results.

A false negative result is when a user takes a COVID-19 test and receives a ‘negative’ result, when in fact they are ‘positive’. This could mean someone has COVID-19 while believing they do not. This poses a risk to your loved ones and community as that person is likely to spread the disease.

We’re sorry if you received an error 20 and we would like to work with you to resolve the situation. We are continually improving our test and we seek to investigate all errors. Your feedback helps us to optimize our tests, so we appreciate your feedback.

Please contact our Customer Support team on 1-888-885-6121 so we can speak with you.

Our error system is just another way Ellume is working to keep you safe.

Paper in the Dropper

What is the little piece of paper in the Dropper?

If you noticed a small slip of paper in the base of the Dropper – well done, great spotting!

It’s an important part of our patented test that interacts with your sample and the processing fluid to enable the test to detect the presence of COVID-19.

So that little slip of paper is really important – please leave it inside your Dropper and please don’t touch it.

Processing Fluid and Desiccant

What is the small white package with orange crystals under my Dropper?

That is a desiccant sachet. They are commonly used in many products, to help absorb moisture and to protect goods from condensation.

It is critical to keep our test components dry and free from humidity, which is why we use the desiccant sachet and the foil packaging.

Do not open or use the desiccant in any part of your test.

Please dispose of the desiccant in general waste - it has done its job and you don’t need it for any part of your test.

Data & result sharing

Your privacy is important to us which is why providing information to support COVID reporting is optional.

This information is used to support the health authorities in monitoring the COVID-19 infection rates around the country.

The information you supply voluntarily is used to support you in the use of the test. Your email is used to provide you with a copy of your result and additional information with you, which you can share as a proof of testing.

How to swab

We know it’s not pleasant, but it’s much more comfortable than many swabs used for PCR COVID-19 tests. Our swab is specifically designed to enable untrained individuals to take a good-quality sample. A good sample is key for any test to generate a reliable result. This is why our swab is slightly deeper than your nostril, includes a child adapter, and our app features animated instructions to make sure everyone can take a good sample.

Please watch the information video and instructions in the app – do not swab yourself until you are instructed within the app.

  • Insert the Swab into your nostril until the cap of the Swab touches your nose. It is important to insert as far as possible to ensure you get a good sample.
  • If the individual is a child aged 2-12 years, insert the Swab until the Child Adapter touches their nose.
  • Sweep the tip of the swab around the walls of your nasal cavity 3 times. Insert the swab in your other nostril and repeat.
    Swabbing both nostrils gives you the best chance of collecting sufficient sample to generate an accurate result. It has been observed in some cases that only one nostril has detectable virus, so it is important to collect from both nostrils.
  • Do not insert the Swab any further if you experience sharp pain or severe discomfort.
  • Do not use this test on children under the age of 2 years.
