About Our COVID-19 Antibody Tests

Senara’s COVID-19 Antibody blood tests identifies the presence of antibodies that indicate that a person had an immune response to COVID-19 (also known as coronavirus or SARS-CoV-2) via natural infection of vaccine response. A positive result to this antibody (IgG) test indicates that you may have had previous exposure to COVID-19 (via natural infection or vaccine, anywhere from 2 weeks to over 6 months ago) and your body has developed antibodies. This is an antibody test used to detect the presence of antibodies, not to diagnose active infections.

Although It may take up to 14 days after the onset of symptoms or vaccine for antibodies to be developed within the body, 91% of people develop such antibodies within the first 8-13 days. Some people infected with COVID-19 will never exhibit symptoms but will have a detectable antibody response. While there is belief that the presence of antibodies may provide immunity to future infections, the data is still evolving as to what levels of antibodies may or may not provide protection. We strongly encourage you to follow-up with your primary care physician to interpret your antibody test results and what that means for your unique health situation.


Senara offers not only testing for COVID-19 IgG antibody testing, both post infection and post vaccination, but also testing for Vitamin D and Zinc levels. Both are key indicators of how well your immune system might respond to viruses and if additional supplementation is needed to boost levels for improved immune support.

Frequently Asked Questions

Am I a good candidate for testing? ▼

All interested persons who have had NO COVID-19 related symptoms for the last 14 days are appropriate candidates for obtaining this test. Please refrain from visiting or scheduling an appointment if you have had symptoms or tested positive for COVID-19 within the past 10 days as you may still be contagious.

What do my test results mean? ▼

IgG Antibody Results for Post Infection

The SARS-CoV-2 IgG and IgM Panel used for detecting prior natural infection is reported as a unit value where results of 11.o or higher indicates antibodies to COVID-19 are detected. Values from 9.0 to 11.0 may indicate initial evidence for detection of antibodies, but further testing is recommended. Results below 9.0 indicate there was no detectable IgG antibodies present. Results do not necessarily rule out infection, however, particularly in those who have been in contact with the virus.

Positive results may be due to past or present infection to non-SARS-CoV2 coronavirus strains, so results should not be used as a sole basis to diagnose or exclude prior infection. Postive sera must take into account other clinical findings and be confirmed with other tests if indicated.

Spike Protein Antibody Results for Post Vaccination

Spike Protein Antibody Test results post vaccination are reported as a reference range, where values of >/= 0.80 U/mL indicates a positive result for anti-SARS CoV-2S presence. Results in excess of that value indicate that your immune system has generated a notable response to either the vaccine or a prior infection. Results are reported in a range of up to 2,500 U/mL for the antibody; test results above the threshold will be indicated as “greater than 2,500 U/mL.”

Values under 0.80 U/mL suggest that your body has not mounted a significant immune response to COVID-19 Vaccination and that you have likely not had prior COVID-19 infection.

It is yet undetermined what Antibody level is correlated to immunity against developing the COVID-19 infection

Am I able to pay using my health insurance? ▼

Senara does not bill any insurance for COVID-19 antibody testing. At your request, we would be happy to provide a walkout receipt to submit to your insurance for direct reimbursement. We currently accept credit card payment only – Visa, Mastercard, Discover, or Amex. Due to high demand and limited space, prepayment is required at this time.

How long do test results take? ▼

Most results will be available in 1-3 business days after your blood draw. In some cases, due to increased demand, turnaround times may be higher.

Is this a blood draw or swab test? ▼

This test requires a blood draw collection from the arm to detect COVID-19 IgG antibodies in the blood. Antibodies in the blood indicate a previous COVID-19 infection or immune response to vaccination. Although it may take up to 14 days after the onset of symptoms for antibodies to be developed within the body, 91% of people develop such antibodies within the first 8-13 days. Some people infected with COVID-19 will never exhibit symptoms but will have a detectable antibody response.

What does “antibody testing” mean? ▼

This serology blood test identifies the presence of antibodies which indicates that a person had an immune response to COVID-19 (also known as coronavirus or SARS-CoV-2). A positive result to this antibody (IgG) test indicates that you may have had a previous exposure to COVID-19, via natural infection or vaccination, and your body has developed antibodies. This test is SPECIFIC to the COVID-19 strain of coronaviruses. The FDA has authorized the use and marketing of this test.
