Information for Test Takers

There are many causes of fever, cough, and shortness of breath. COVID-19 is just one condition that may cause these symptoms. This test does not rule out the possibility of other illnesses and infections that may be present instead of or in addition to COVID-19.
If you feel like you are having a medical emergency, please call 9-1-1​. You should contact your healthcare provider​ if your symptoms get worse or you experience any new symptoms. ​​If you are experiencing trouble breathing, persistent pain or pressure in your chest, new confusion, inability to wake or stay awake, bluish lips or face, or any other symptoms that are severe or concerning to you, please seek immediate medical care.

What is Concentric by Ginkgo’s COVID-19 PCR test?

Ginkgo Bioworks, Inc. (“Ginkgo”) has engaged Infinity BiologiX LLC (“IBX”) to allow us to provide access to The Infinity BiologiX TaqPath SARS-CoV-2 Assay (the “IBX Test”) performed in the Infinity BiologiX Genomics Laboratory, a CLIA-certified high complexity laboratory.

The version of the IBX Test offered by Concentric by Ginkgo is a saliva-based test.

The IBX Test being offered by Concentric by Ginkgo is a PCR (polymerase chain reaction)-based test that is designed to detect the virus that causes COVID-19 in respiratory specimens, for example nasal, oral swabs, or saliva.

A PCR (polymerase chain reaction) test checks for genetic material (viral RNA) produced by the virus. This is used to detect the presence of the virus that causes COVID-19.

Is this test FDA-approved or cleared?

No. This test is not yet approved or cleared by the United States FDA. When there are no FDA-approved or cleared tests available, and other criteria are met, FDA can make tests available under an emergency access mechanism called an Emergency Use Authorization (EUA). The EUA for this test is supported by the Secretary of Health and Human Services (HHS’s) declaration that circumstances exist to justify the emergency use of in vitro diagnostics for the detection and/or diagnosis of the virus that causes COVID-19.

This EUA will remain in effect (meaning this test can be used) for the duration of the COVID-19 declaration that circumstances exist justifying emergency use of In Vitro Diagnostics (IVDs) for the detection and/or diagnosis of COVID-19, unless it is sooner terminated or revoked (after which the test may no longer be used).

This test has been authorized by FDA under an EUA for use by authorized laboratories.

This test has been authorized only for the detection of nucleic acid from SARS-CoV-2, not for any other viruses or pathogens.

Is this a viral test (i.e. nucleic acid or antigen test) or an antibody test?

The IBX Test is a viral test. The CDC recommends viral tests to diagnose infection with COVID-19. Unlike viral detection methods that can detect currently infected persons, antibody tests help determine whether the individual being tested was previously infected, even if that person never showed symptoms. Antibody tests for COVID-19 can play an important role in surveillance and epidemiologic studies, which can provide insights into the transmission dynamic of the virus among the general population. The CDC recommends getting viral tests in certain situations. To learn more, visit: https://www.cdc.gov/coronavirus/2019-ncov/hcp/testing-overview.html

Who should get tested?

The CDC indicates (as of September 18, 2020) that a healthcare provider may determine that you should get tested based on a number of considerations, including:

  • If you have symptoms of COVID-19
  • If you have been in close contact, such as within 6 feet of a person with documented SARS-CoV-2 infection for at least 15 minutes and do not have symptoms
  • If you are in a high SARS-CoV-2 transmission zone and attended a public or private gathering of more than 10 people (without universal mask wearing and/or physical distancing)
  • If you work in a nursing home
  • If you live in or receive care in a nursing home
  • If you are a critical infrastructure worker, healthcare worker, or first responder
  • You are a member of a specific group of people that a healthcare provider or public health official recommends for testing (e.g., pregnant women admitted for labor and delivery, surgery).

How does the test work?

Prior to testing, authorization from a physician is required. This process is enabled by our platform.

After an organization enrolls, its members are invited to sign in to our portal and fill out a health questionnaire. Healthcare providers are provided by PWNHealth, who will evaluate your questionnaire responses and determine who is eligible for testing. PWNHealth is an independent healthcare provider network that provides oversight services and has partnered with Concentric’s platform providers, ixLayer and One Codex.

Eligible individuals can then proceed to the designated Test Center at a specified time in order to collect their sample.

Samples are shipped to our partner laboratory at Infinity BiologiX Clinical Genomics Laboratory, and results are communicated back to the individuals and organizations through our portals powered by ixLayer and One Codex (who provides this portal in compliance with all applicable privacy laws and individual authorization).

What will my COVID-19 PCR test results tell me?

A PCR test can be used to detect the virus that causes COVID-19 on the day of sample collection. If your results are positive, it is important to limit your exposure to other people and continue to monitor your symptoms. If your results are negative, the test did not detect the presence of the virus that causes COVID-19 in the sample you provided.

For more information on positive and negative results associated with the IBX Test, please see the patient fact sheet.

After receiving your results, you will have an opportunity to speak with a licensed physician from our healthcare provider network partner, PWNHealth, who can answer any questions you may have about your test results and help determine next steps in care.

Depending on your test results, PWNHealth’s Care Coordination Team may attempt to contact you to notify you of your results and schedule a telehealth consult with a physician or other healthcare provider.

Depending on your test results, PWNHealth’s Care Coordination Team may attempt to contact you to notify you of your results and schedule a telehealth consult with a physician or other healthcare provider.

How do I prepare for the test?

You should NOT eat, drink, smoke, or chew gum for 30 minutes before giving your saliva sample.

You do not need to do anything to prepare for the test. You do not need to fast or stop taking any medications before testing. Further instructions will be provided to you at the lab or in your test kit.

What are the known and potential risks and benefits of the test?

Potential risks include:

  • Possible incorrect test results. For more information, please see the below FAQ section “How to interpret the results.”

Potential benefits include:

  • The results, along with other information, can help your healthcare provider make informed recommendations about your care.
  • The results of this test may help limit the spread of COVID-19 to your family and others in your community.

Where can I get more information?

We encourage you to consult our FAQ or contact us at support@concentricbyginkgo.com.

Information for Test Takers Younger than 18 Years of Age

If your child’s condition changes before you are able to obtain the test or the test result, please contact your pediatrician or visit your local emergency room as soon as possible.

Can my child get tested?

Testing is available for children 4 years of age and older. If your child has new or worsening emergency warning signs, such as trouble breathing, persistent pain or pressure in your chest, new confusion, inability to wake or stay awake, bluish lips or face, or any other symptoms that are severe or concerning to you, call 911 or seek emergency medical attention instead of ordering this test.

Should my child get a COVID-19 viral test (i.e. nucleic acid or antigen test)?

A healthcare provider may provide an order for a COVID-19 viral test so that your child may be tested for detection of the virus that causes COVID-19 if the healthcare provider suspects your child to have COVID-19. A healthcare provider may determine that your child should get tested based on a number of reasons and considerations, including if:

  • They have symptoms of COVID-19
  • They have been in close contact with someone with confirmed COVID-19 for at least 15 minutes and do not have symptoms
  • They do not have symptoms, have been in a high SARS-CoV-2 transmission zone and attended a gathering of more than 10 people (without wearing a mask and/or physical distancing)

If you have any other questions, we recommend that you speak with your child’s primary healthcare provider about testing recommendations to see if testing is right for your child at this time.

How do I prepare my child for testing?

  • It is important to set realistic expectations. While some children may enjoy the novelty of spitting into a tube, some children may find the testing experience to be stressful or worry generally about the need to take a test. Take time to reassure your child and after the test, praise and comfort your child as needed.
  • Make sure your child is tested when they are less likely to be tired or hungry. The test requires that your child should not eat, drink, smoke, or chew gum for 30 minutes before giving their saliva sample; however, your child does not need to fast or stop taking any medications before testing for longer than the required 30 minutes. Eating and drinking plenty of water before the 30 minute refraining period will help lower the risk of lightheadedness and can help make the process smoother.
  • For small children, it may be helpful to talk about feelings or practice calming techniques before the test. You can do this by making a game of staying still or practicing breathing exercises with your child. It may also be helpful to distract your child during the procedure.
  • Before testing, discuss any concerns and questions with your child’s primary healthcare provider. Further instructions will be provided to you at the lab or in your test kit.

  • What is COVID-19?

    COVID-19 is caused by the SARS-CoV-2 virus. The virus, which can cause mild to severe respiratory illness, was first identified in Wuhan, China, and has now spread globally, including the United States. There is limited information available to characterize the spectrum of clinical illness associated with COVID-19 but it likely spreads to others when a person shows signs or symptoms of being sick (e.g., fever, coughing, difficulty breathing, etc.).

How to Interpret the Results
When to Use the Test
  • Who is eligible to take a test?
    An independent physician will determine whether to authorize your test request, if appropriate. This physician will be provided through PWNHealth. Before receiving a test, you will be asked to complete a short health questionnaire, which this physician will review.
    Our healthcare provider network partner, PWNHealth, might deem certain individuals ineligible to take a test. In this case, PWNHealth will provide additional guidance, including what to do if the individual develops severe symptoms. Since advice given by PWNHealth is coming from an individual physician making medical recommendations, Concentric cannot vouch for advice given to you by a PWNHealth physician.
  • Who is PWNHealth?

    PWNHealth is an independent healthcare provider network that provides oversight services to you in connection with the laboratory testing that you have requested. PWNHealth and its services are independent from the laboratory and company from whom you requested and registered for a test and their services.

  • Is this a viral test or an antibody test?

  • Who should not get a COVID-19 PCR test?
    You should not get tested if you:
    • Currently have severe symptoms that limit your daily activities. Seek medical attention right away if this is the case.
    • Tested positive for COVID-19 in the last 3 months. Speak with your healthcare provider prior to getting tested.
  • Who is at highest risk of serious illness from COVID-19?
    COVID-19 is a new disease and there is limited information regarding risk factors for severe disease. Based on currently available information and clinical expertise, older adults and people with underlying medical conditions are at higher risk for severe illness from COVID-19. Please note that the list of underlying conditions found below is meant to inform clinicians to help them provide the best care possible for patients, and to inform individuals as to what their level of risk may be so they can make individual decisions about illness prevention. We are learning more about COVID-19 every day. The information included here is potentially subject to rapid change as the science evolves. Please check the CDC’s website referenced at the bottom of this section to access CDC’s most up-to-date guidance.
    As you get older, your risk for severe illness from COVID-19 increases. For example, people in their 50s are at higher risk for severe illness than people in their 40s. Similarly, people in their 60s or 70s are, in general, at higher risk for severe illness than people in their 50s. The greatest risk for severe illness from COVID-19 is among those aged 85 or older.
    People of any age with the following conditions are at increased risk of severe illness from COVID-19:
    • Cancer
    • Chronic kidney disease
    • COPD (chronic obstructive pulmonary disease)
    • Immunocompromised state (weakened immune system) from solid organ transplant
    • Obesity (body mass index [BMI] of 30 or higher)
    • Serious heart conditions, such as heart failure, coronary artery disease, or cardiomyopathies
    • Sickle cell disease
    • Type 2 diabetes mellitus
    COVID-19 is a new disease. Currently, there are limited data and information about the impact of underlying medical conditions and whether they increase the risk for severe illness from COVID-19. Based on what we know at this time, people with the following conditions might be at an increased risk for severe illness from COVID-19:
    Children who have medical complexity, who have neurologic, genetic, metabolic conditions, or who have congenital heart disease might be at increased risk for severe illness from COVID-19 compared to other children.
