There are two kinds of tests for COVID-19: a viral test and an antibody test.
- A viral test (nasal or oral swab) tells you if you have a current infection
- An antibody test (blood test) tells you if had a previous infection
Viral Tests: Testing for current infection
To learn if you have a current infection, viral tests are used. A viral test is collected by a nasal or oral swab at a testing center in our area.
Who should be tested?
- The decision to get tested depends on several different factors including how sick the patient is, what medical problems the patient has and who resides in the patient’s household (e.g. an immunosuppressed family member, a parent who is a health care worker)
- At this time, we still encourage testing only if you have symptoms suggesting a COVID-19 infection.
- If you have symptoms suggesting COVID-19 and want to get tested, please call our office.
- If you have gotten tested and are awaiting the results, please isolate/quarantine to avoid possibly spreading the infection to others.
Interpreting the results
- If you test NEGATIVE for COVID-19 by a viral test while you have symptoms, then you likely do NOT have COVID-19. Though we know that there are some false negatives, meaning people who actually DO have COVID but get a negative test result, a false negative result is unlikely.
- If you test POSITIVE for COVID-19 by a viral test then you have an active infection. Please quarantine in your home and isolate as much as possible from others in your home. If you test positive, we can discuss with you how to minimize spread within your home and when you can safely leave isolation.
Antibody Tests: Testing for past infection
Antibody tests are blood tests that check if your body has antibodies from a previous infection with the virus. Antibodies are proteins our immune system makes when we are exposed to a virus and continue to circulate in our blood after we have recovered from the infection. COVID-19 antibody tests cannot be used to see if you have a current infection, as sometimes the antibodies cannot be detected for weeks after the initial infection.
We use antibody testing for many other diseases to tell us if a patient has had an infection or has immunity to a disease. For diseases that have been studied over time we know what level of antibody is effective and we know whether that antibody can give you temporary or permanent immunity. However, since COVID-19 is a new disease we don’t have all the facts yet.
Cautions regarding antibody tests:
- We do not know at this time if antibodies provide immunity against getting re-infected
- We do not know how specific the antibody tests are for detecting antibodies to SARS-CoV-2 versus closely related coronaviruses such as the common cold.
- There are many tests available right now but few of them have been FDA approved, meaning we do not know how accurate these tests are. In other words, if the test says you have antibodies, or don’t have antibodies, how likely is that to be true?
Given all of these cautions, we are not currently recommending antibody testing for most people. The only scenario in which we DO recommend testing is if you have had a positive COVID-19 viral test and are interested in plasma donation.
Why we don’t think you should get an antibody test now:
- We are concerned that you may get a “positive” result when you don’t actually have antibodies to COVID. This could happen because these tests are still very new, they were released to the market before the FDA validated them and you may have very similar antibodies from a very similar virus you’ve had in the past. If you got a positive result you may interpret that to mean you are immune, when in fact you are not. This could be dangerous as you may not be as rigorous about wearing a mask or social distancing and accidentally expose yourself or others.
- We don’t know yet what having antibodies to COVID-19 means. We don’t know if those antibodies confer immunity and, if so, how long that immunity lasts.
- Antibody tests are usually expensive. Since many of the tests on the market are not FDA approved they may not be covered by insurance.
- Antibody tests require a blood draw in a doctor’s office or hospital. We usually do everything we can to minimize blood draws in kids to avoid discomfort.
The scientific community is working furiously to learn more about COVID-19 each and every day. We are hopeful that soon we will know more about COVID-19 antibodies and immunity. We are also hopeful that the FDA will review the tests on the market and guide us to which tests are the most accurate. We will continue to follow this issue closely to give you the best guidance and we will update you when our recommendations change.
For now, please continue to social distance, stay home if you or anyone you’ve been in contact with is sick, and wear a mask when social distancing is not possible.

You may have seen recent news reports about a syndrome affecting kids during the COVID-19 pandemic called Pediatric Multisystem Inflammatory Syndrome. This new syndrome has only been recently detected and is still being investigated. We know some of these reports can be scary so we would like to try to separate fact from fiction and give you clear information.
The first reports about this syndrome came out of the United Kingdom at the end of April. Last week, the first U.S. cases were reported in New York City. Today, cases have been reported in Connecticut. While this new syndrome is serious, the good news is that the number of children affected so far is very small compared to the staggering number of people affected by COVID-19.
What is Pediatric Multisystem Inflammatory Syndrome?
This syndrome is a new health condition in which children who have had the coronavirus and recovered from it develop an excessive immune response that causes significant inflammation to their organs. Children with this syndrome have prolonged fever (greater than 5 days), their blood work shows inflammation, and they present with certain clinical findings such as:
- abdominal pain
- eye redness
- enlarged lymph nodes or glands on one side of the neck
- skin rash
- red, cracked lips or a red “strawberry” tongue
- swollen hands or feet
IMPORTANT: Children with this syndrome will look very ill. They will not bounce back from their fever with Tylenol or ibuprofen. They will have persistent symptoms over several days. This is NOT something you can easily miss.
What should I do if I think my child has this new syndrome?
If you are concerned that your child meets these criteria, but she only has mild symptoms, please call our office. If your child is very ill and it is an emergency, as always, please call 911.
If my child was sick before (either with a positive COVID test or not) should I get my child checked?
At this time, if your child has recovered from a prior illness and is doing well, there is no recommendation to do so. If your child becomes ill and has a high fever for several days in a row please call our office so we can evaluate him or her.
What is Kawasaki Disease and is it related?
Kawasaki Disease is a rare inflammatory disease that only occurs in children. It is still unclear how or if Kawasaki Disease and COVID-19 are related but they have similar symptoms and presentations.
Kawasaki Disease existed long before COVID-19, and we are not sure what causes the immune systems in these children to go into overdrive. In Kawasaki’s Disease, children present with a prolonged fever, some clinical symptoms (rash, strawberry tongue, swollen lymph nodes, swelling of hands and feet) and signs of inflammation throughout the body eventually including swelling of the blood vessels of the heart. Typically, there are about 3,000 cases per year in the United States. This is an easily treatable condition and typically children do not have long-term complications.
Is there treatment for Pediatric Multisystem Inflammatory Syndrome?
Doctors are working hard to determine the best treatment. If we suspect your child has this syndrome, we would likely direct you to a hospital or emergency room for evaluation. Patients with Kawasaki Disease or Pediatric Multisystem Inflammatory Syndrome need monitoring and specialist evaluation. Treatments for Kawasaki Disease are being tried for patients with this new syndrome. These treatments include supplemental doses of immunoglobulin (intravenous immunoglobulin, IVIG) and steroids. Rarely, children have gotten very sick and needed to be in an intensive care unit for fluids, medications for blood pressure, and assistance with breathing. While this new disease is serious, remember that children with this syndrome will look very ill and that this is NOT something you can easily miss.
