Details

Tests for current COVID-19 infectionThe Active Infection COVID-19 Saliva Test identifies the presence or absence of RNA from the SARS-CoV-2 virus in patients’ cells. The test is performed by RT-PCR technology, the current preferred testing method of the Centers for Disease Control (CDC) to identify an active COVID-19 infection.

Note: This is not a test for COVID-19 antibodies. To identify whether you have developed an adaptive immune response to the virus as part of a prior infection or vaccine, please view our COVID-19 Antibody Test.

Easy painless at-home saliva collectionCan you spit? I bet your child can! If so, then take this test. Just spend as little as 2 minutes spitting into the collection device. Saliva sample collection supplies are included in your kit along with detailed instructions. You collect your non-invasive sample from the comfort of home and mail it to a certified lab with prepaid overnight shipping.

Recommended for individuals 5 years old and overOur at-home saliva COVID test, recommended for individuals 5+, makes the testing experience a lot more bearable. Considering how invasive the typical COVID-19 swab test is, your kid is sure to put up a fight — or shed some tears.

Why should I, or my child, be tested for a COVID-19 Active InfectionAnyone ages 5+ can test for an active COVID-19 infection. This test is recommended for use with saliva samples that are self-collected by an individual age 18 years or older, or that are collected by an adult from an individual 5 years of age and older. This test is intended for those who have been recently exposed to COVID-19, are experiencing symptoms, need school/work/travel clearance or just want to test proactively to have peace of mind.

General Symptoms
• Fever between 100.4°F - 102°F
• Flu-like symptoms (chills, runny or stuffy nose, whole body aches, a headache, and/or feeling tired)
• New loss of taste or smell

Respiratory Symptoms
• A new or worsening cough or sore throat
• Shortness of breath

When would this test not be helpful?Not intended for individuals experiencing severe COVID-19 symptoms who should seek emergency medical care right away. The test taker must be 5+ years old. This test is not available for patient collection in New York State.

Can I buy now and use this test later?Test now or within one year of purchase. This kit has a guaranteed expiration date of at least 5 months. That’s great news if you are buying a "just-in-case" COVID-19 test to keep in your medicine cabinet or gifting to a friend or family member for later use.

When should I, or my child, get tested for COVID antibodies?

It usually takes between 1 to 3 weeks after infection or vaccination for the body to make COVID-19 antibodies. To avoid recollection, a COVID antibody test should ideally be administered no sooner than 21 days after a suspected exposure or immunization.

What effect does vaccination have on COVID antibodies?

COVID-19 vaccines teach your body to produce antibodies to the spike proteine of SARS-CoV-2, to fight infection from the virus that causes COVID-19. If you get an antibody test after receiving a vaccine, you might test positive by some (but not all) antibody tests. This depends on which type of antibody the specific test detects.

What are the two main types of COVID antibody tests?

This is a spike protein IgG COVID antibody test. The other methodology checks for nucleocaspid IgG antibodies.

 

Spike Protein IgG Antibody Tests: A spike protein COVID-19 IgG antibody test detects an immune response to a previous COVID-19 infection or vaccine. It is useful in evaluating for protective antibodies against the SARS-CoV-2 virus, whether the antibodies were acquired from a previous COVID-19 infection or vaccine immunization. This semi-quantitative spike protein IgG COVID-19 antibody test provides a Detected/Not Detected result along with a COVID Antibody Score (level).

 

Nucleocapsid IgG Antibody Tests: A nucleocapsid protein COVID-19 IgG antibody test only detects an immune response to a previous Covid-19 infection. It is especially useful to help evaluate whether a vaccinated individual had previous exposure to SARS-CoV-2, but also used by non-vaccinated individuals too. Keep in mind that (a) nucleocapsid proteins may not be as long-lasting, (b) IgG antibodies develop to spike but not to the nucleocapsid viral protein in many asymptomatic and light COVID-19 cases and (c) are not produced by vaccines authorized in the United States. If you're vaccinated and want to confirm you had a previous COVID infection, you can check out our nucleocapsid COVID antibody test that exclusively evaluates for antibodies from a prior COVID illness.

What is the primary purpose of the spike protein component of the SARS-Co-V2 virus?

The spike protein is found on the surface of SARS-CoV-2, the virus causing COVID-19.

 

Spike Protein's Role in Natural Infection

The key feature of the spike protein is to allow the virus to penetrate host cells within your body and cause infection. When SARS-CoV-2 enters the body, its spike protein acts as a key, gaining entry to the cell. The immune system responds by producing protective anti-spike antibodies that bind to the invading virus, blocking or neutralizing its effects.

 

Spike Protein's Role in Vaccination
Without the S protein, viruses like the novel SARS-CoV-2 would not be able to interact with host cells to cause infection. As such, the spike protein makes an ideal target for vaccines. All currently available COVID-19 vaccines in the United States currently target the immune system to produce a protective anti-spike antibody response.


This is a spike protein IgG COVID antibody test and will detect a protective immune response to a previous COVID-19 infection or vaccine and provide your antibody level.

What does a positive COVID antibody test result mean?

A positive COVID antibody test result shows your blood sample demonstrated antibodies made from an immune response to either a previous infection or vaccination for the virus that causes COVID-19, and at the time of the test, the antibodies were still present circulating in the blood.

 

Some antibodies made for the virus that causes COVID-19 provide protection from getting infected. CDC is evaluating what degree of safety COVID antibodies provide and how long protection from antibodies might last. Although infection is possible after having produced antibodies from vaccination or prior infection, having antibodies plays an important role in helping prevent severe COVID-19 disease.

What does a negative COVID antibody test mean?

A negative COVID antibody test result shows your blood sample demonstrated, at the time of collection, no detectable circulating antibodies to the SARS-CoV-2 coronavirus. A not-detected finding does not preclude the possibility of a previous vaccine or infection. If an individual was previously infected or vaccinated, they might not have produced spike protein antibodies - not everybody does. Also, antibodies fade over time, so if an individual were infected or vaccinated some time ago, they may now have disappeared.

How do I self-collect an At-Home Covid Antibody Test?

To simplify and make COVID antibody testing less painful, 4U Health uses a fingerstick dried blood spot sample method as part of its self-collection kit. To learn how easy it is to collect a dried blood spot specimen and mail it to the lab for testing, you can view the following self-collection instructions video.

Can I buy now and use this test later?

Test now or later. Your self-collection test kit will arrive with an expiration date of at least 6 months from your order date. That’s great news if you are buying multiple kits for yourself or want to gift to a friend or family member for later use. All test samples must be collected and mailed by the expiration date on your kit.

Can I gift this test to a friend or family member?

All 4U Health tests are eligible for gifting. In fact, they make great presents. The recipient who receives your gift will simply open the kit, register it, and follow the collection instructions. Within a few days of sending to the lab, your friend or family member will receive secure electronic HIPAA compliant results all thanks to your generosity.

If I know I have COVID antibodies, what should I do if I experience COVID-19 like symptoms?

Any person, whether they have antibodies or not, should get a viral test to evaluate for a current infection if they have COVID-19 like symptoms or have a suspected or confirmed exposure to someone with COVID-19. For information about an at-home saliva PCR COVID-19 test option, click here.

What are common symptoms of COVID-19?

Many people who are infected with COVID-19 are asymptomatic, meaning they do not experience symptoms. If you want to find out if you or your child had COVID-19, 4U Health’s at-home COVID-19 antibody test is a simple way to learn your antibody status. Symptomatic patients with COVID-19 often report a wide range of symptoms anywhere from 2 thru 14 days after exposure to the virus. If you have experienced one or more of the following symptoms, your likelihood of having had a COVID-19 infection is increased.

• Fever or chills
• Cough
• Sore throat
• Sinus congestion or runny nose
• Loss of taste or smell
• Shortness of breath or difficulty breathing
• Fatigue or general body weakenss
• Muscle or body aches
• Nausea or vomiting
• Diarrhea

When would this test not be helpful?

A COVID antibody test may NOT be right for you if you are trying to diagnose COVID-19. Note, COVID antibody tests are not approved to diagnose for an active COVID-19 infection. A COVID antibody test only shows whether the body has developed an adaptive immune response to the virus as part of a prior infection or vaccine. To test for an active COVID-19 infection, click here.

 

You should not get a COVID antibody test if:
• You feel sick or have had a fever within the last 3 full days; please contact a healthcare provider.

• It is less than 10 days since you tested for and were diagnosed with COVID-19.

• You were directly exposed to COVID-19 in the past 14 days.

• It is less than 2 weeks since you had your complete vaccination for COVID-19.

 

• You live in New York State, Pennsylvania, or Maryland. This serology test is not available for self-collection in NY, PA or MD.

 

• You are 4-years-old or younger.

What is the intended use of the COVID-19 Antibody Self-Collection Test?

Covid antibody testing is intended for use as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection. The test provides semi-quantitative detection of IgG antibodies to SARS-CoV-2 in human fingerstick by dried blood spot (DBS) specimens. Antibody tests are self-collected at home by individuals age 18 years or older or collected by adults from individuals 5 years of age and older using the COVID-19 Self-Collected Antibody Test System. Home covid antibody test kits are ordered when appropriate by a healthcare provider licensed to practice medicine in the state where a specimen is self collected. The telehealth medical practitioner order is included in the cost of the test.


At this time, it is unknown for how long antibodies persist following infection (or vaccination) and if the presence of antibodies confers protective immunity.


This at home self collection serology test system has not been FDA cleared or approved but has been authorized for emergency use by the FDA. This test system has been authorized only for detecting IgG antibodies to SARS-CoV-2, not for any other viruses or pathogens.


The emergency use of this at home self collection serology test system is only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of in vitro diagnostics for detection and/or diagnosis of COVID-19 under Section 564(b)(1) of the Federal Food, Drug and Cosmetic Act, 21 U.S.C. § 360bbb-3(b)(1), unless the declaration is terminated or authorization is revoked sooner.

Where is my lab test performed?

4U Health offers at home collection tests with mailing to certified laboratories. The performance of all testing on your samples complies with state and federal regulations. We only work with the best laboratories and health experts. Your Health Consultant provides medical oversight. Our test meets nationwide standards and are as accurate as tests done and services provided in a doctor’s office or hospital.

 

The laboratories we work with are CLIA high complexity testing organizations at the forefront of infectious disease services.

How is my privacy protected?

Rest assured; HIPAA web security protocols protect your data along every step of the way to finding out your COVID-19 antibody status. Keeping your personal data secure is important to us. We only share your information where required to deliver our products and services or where we have a legal basis to do so. Your results are securely protected and available for review online; always secure but easily accessible only to you.

Will my COVID-19 Antibody Self-Collection Kit be covered by insurance?

Pay upfront and receive no surprise medical bills. 4U Health is not enrolled in Medicare or any other private insurance network. This test is not eligible for Medicare or any other federal or state-funded insurance program reimbursement.

Are there limitations to COVID-19 antibody tests? 

It usually takes between 1 to 3 weeks after infection or vaccination for the body to make COVID-19 antibodies. A false negative result may sometimes occur if you get an antibody test too soon after being exposed or vaccinated and your body has not yet made enough antibodies to be detected by the test. To help avoid a false negative result, a COVID antibody test should therefore be administered no sooner than 21 days after a suspected exposure or immunization.

 

Additionally, some immunocompromised individuals, often those with weakened immune systems due to a medical condition or certain medications, may not develop detectable levels of antibodies after exposure or vaccination.

 

Although rare, a false positive test result may occur if the test cross-reacts and detects antibodies from other coronaviruses you may have been exposed to, like the virus that causes the common cold.

 

To properly interpret your results, it's always advised you follow up with a healthcare provider, who can evaluate your medical history.

Can a COVID-19 antibody test be used to determine my immunity level? 

A COVID antibody test can help identify individuals who have developed an immune response after exposure to COVID-19 or vaccination.

 

Although infection is possible after having produced antibodies from vaccination or prior infection, having antibodies is thought to play an important role in helping prevent severe COVID-19 disease. The CDC advises it should not be used to determine the level of immunity or protection you have. Evidence is still being collected and studied to determine if antibodies, and at what level, provide protective immunity against SARS-CoV-2 (COVID-19) specifically.

 

Follow up with your healthcare provider for additional guidance on how to interpret your test results.

Can a patient's COVID antibody level be compared for interval changes to results produced from another lab (different lab test)? 

In reference to antibody numbers, please note there are no generally recognized international standardized units or antibody levels for COVID Antibody Tests allowed by the FDA at this time. As such, if you already had an antibody level from another test, it is generally advised you follow up with the same test by the same lab to evaluate for an interval change between two results. Again, it is generally not advised to compare an antibody level from one type of COVID Antibody test to another different type of antibody level test for an interval change, as there is no general standardized reporting units or levels between different covid antibody test assays at this time.

 

Follow up with your healthcare provider for additional guidance on how to interpret your test results, particularly how they may compare to previous results obtained from another test assay.
