Details

Check your current COVID-19 antibody statusThis FDA authorized test allows you to check if you have produced (and still have) antibodies from a prior COVID-19 infection or vaccine.

When infected with COVID, your immune system typically makes specific antibodies to fight it. Your immune system can also safely learn to make antibodies through a COVID vaccine. Once you have antibodies to a particular disease either thru prior infection or vaccination, including COVID, antibodies usually provide increased protection from severe disease, hospitalization and death. Bear in mind, if an individual was previously infected or vaccinated, they might not have produced 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. This test allows you to verify your current COVID antibody status to confirm the body has produced and still has detectable COVID-19 antibodies.

What's measuredThis serology (antibody) test provides a qualitative determination, which indicates whether you have detectable circulating antibodies to COVID-19 in your blood. And now for the science: the COVID-19 Antibody Self-Collection Test detects IgG antibodies to the S1 spike protein domain of SARS-CoV-2, the virus that causes COVID-19. Spike protein IgG antibodies are produced by an immune response to a previous COVID-19 infection or vaccine.

Note: This is not a test to diagnose an active COVID-19 infection and would only be appropriate to identify whether you have developed an immune response to the virus as part of a prior infection or vaccine. To determine if you are currently infected, check out our COVID-19 Active Infection Test.

Easy at-home test collection kitIn as little as five minutes, collect your sample from the comfort and privacy of your home, mail it in to our certified lab with prepaid shipping then receive your secure digital results within a few days. Your kit includes finger prick (tiny blood drop) sample collection supplies along with detailed instructions.

And parents we've got you covered — hospitals use this method of collection on newborns; it's the least intrusive and painless way to acquire a blood sample.

Approved for indivduals 5-years-old and overUnderstanding your child’s antibody status gives you powerful insight as to whether they had a prior or recent COVID-19 infection and already have some level of antibodies and protection against COVID-19. This test is approved for parents to easily collect a fingerstick dried blood spot (DBS) specimen from a kid five and older.

Adults 18-years-old and over may self collect their own specimens for this test.

Discreet packagingYour mail-in antibody test kit is delivered in a plain envelope for a confidential testing experience insuring your medical privacy.

Certified lab resultsYou can expect timely, secure electronic results delivered to you in just a few days. The best part is we only work with federal and state-certified laboratories. This means your results are of the highest quality, and you can share them with any clinician, travel provider, school, or employer with certainty they will be accepted.

What are COVID antibodies?

COVID Antibodies are proteins created by your immune system that help you fight off a COVID-19 infection. They are made after you have been infected by the SARS-CoV-2 virus or have been vaccinated against an infection. 

Antibodies help clear a viral infection and may protect you from getting the same infection for some period of time afterward. How long this protection lasts is different for each disease and each person. At this time, researchers do not know whether the presence, or at what quantity antibodies incur immunity to COVID-19; or if they do, how long immunity will last. Howbeit, per the CDC if a reinfection happens, having antibodies plays an important role in helping prevent severe illness, hospitalizations, and death.

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

A COVID antibody test, sometimes referred to as a COVID serology test, looks for antibodies in your blood that fight the virus that causes COVID-19. In both children and adults, COVID antibody testing can help identify if you were exposed to SARS-CoV-2 coronavirus, and if exposed, check whether or not your body has produced a protective immune response. 

 

COVID antibody tests may be helpful if you want to know whether your body has current detectable levels of COVID-19 antibodies because:

 

•  You were never diagnosed with COVID-19 and are looking to determine if you may have been previously infected with the virus.

 

•  You have previously tested positive for COVID-19 and want to know if your body has produced a protective immune response.

 

•  You received a COVID-19 vaccine and want to know if your body has produced an immune response.

 

•  You want to intermittently track if antibody levels remain detectable over time.

Can you test positive for antibodies if you never had symptoms of COVID-19 or never received a COVID-19 vaccine? 

You may test positive for antibodies even if you have never had symptoms of COVID-19 or have not yet received a COVID-19 vaccine. This can happen if you had an infection without symptoms, which is called an asymptomatic infection.

 

A study published in JAMA Network Open found that, globally, more than 40% of confirmed COVID-19 cases were asymptomatic. Moreover, the Mayo Clinic reports up to 50% of children and adolescents might have COVID-19 with no symptoms.

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 therefore 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

 

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 useful to help evaluate whether the test taker had previous exposure to SARS-CoV-2, with the limitations 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. 

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 August 10, 2022. That’s great news if you are buying to gift to a friend or family member for later use. All test samples must be collected and mailed by the expiration date.

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 qualitative 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.
