Antibody Tests for COVID-19

Antibody tests look for the presence of antibodies, which are proteins made in response to infections. Antibodies are detected in the blood of people who are tested after infection; they show the body’s efforts to fight off a specific infection.

How It Works

_______

Antibodies are produced by the body in response to invading foreign particles such as microorganisms and viruses. They play a key role in the immune system’s response to infection and disease.

IgM is usually the first antibody to be produced, and it indicates that you may be infected and that your body is fighting it. If this is positive, you may still be infectious.

IgG antibodies develop within 7 to 10 days after symptoms begin and it remains in the body after the infection has passed. This antibody indicates you may have had COVID-19 in the recent past, but there is no way of telling how long ago you had it. This antibody can potentially help you fight a future recurrence of the infection.

The IgM‐IgG combined assay has better utility and sensitivity compared with a single IgM or IgG test. It can be used for the rapid screening of SARS‐CoV‐2 carriers, symptomatic or asymptomatic.

 

FAQs

We are doing antibody testing, this is not the COVID Test, let me
explain. The only COVID test is the nasal swab. What they are doing is swabbing our inner throat and nostrils trying to harvest live virus or genetic material. They then put that into a petri dish and grow it over several days to test for the presence of COVID-19.

The swab test will only tell you if you actively have the infection, and cannot tell you if you had it before. Also, it is taking 2+ weeks to get an appointment and then another 1-2 weeks to get your results back.

We are testing for antibodies. Antibodies are your bodies natural
reaction to being infected with any virus, bacteria, fungi, etc. And it can take several days develop. With our antibodies test we can tell you two things: are you currently infectious, or have you been infected in the last few weeks/months. The only if and or but of this test is that if you were infected recently within the last 7 days, you may still test negative although you are actually positive. If that is your fear, that you were infected within the past 7 days, my suggestion is to return in a week or two and repeat the test.

It is $97 for the test, the results are available in 20 minutes. Appointments are required before 3PM, we accept walk-ins between 3PM – 4PM. We test for igG & igM antibodies. To learn more in detail, the cdc.gov website is a great resource. 

 

There is no 100% accurate test for COVID-19 available. Tests vary in accuracy. If you were just exposed (ie. at a restaurant last night) it is possible that your test will result negative. We recommend retesting 7 to 14 days later for an accurate result. Symptoms of COVID-19 include, but are not limited to:

FEVER – SHORTNESS OF BREATH – DRY COUGH – LOSS OF SMELL/TASTE – EXTREME PAIN – WEAKNESS/BODY ACHES

This test cannot confirm virus presence, only provide evidence of recent infection, but it provides important immunological evidence for physicians to make the correct diagnosis along with other tests and to start treatment of patients. 

  • Although the presence of anti-SARS-CoV-2 antibodies when detected using a testing algorithm with high positive predictive value for the context of use likely indicates at least some degree of immunity, until the durability and duration of immunity is established, it cannot be assumed that individuals with truly positive antibody test results are protected from future infection.
  • Asymptomatic persons who test positive by serologic testing and who are without recent history of a COVID-19 compatible illness have a low likelihood of active infection and should follow general recommendations to prevent infection with SARS-CoV-2 and otherwise continue with normal activities, including work.
  • Persons who have had a COVID-19-compatible or confirmed illness should follow previous guidance regarding resumption of normal activities, including work.
  • There should be no change in clinical practice or use of personal protective equipment (PPE) by health care workers and first responders who test positive for SARS-CoV-2 antibody.
