Antibody Test

What is IgM?

The first antibody our bodies make when we fight a new infection. It often disappears soon after our bodies fight off an infection.

What is IgG?

The most common antibody in our bodies. It can be found long after an infection.


IgM IgG Interpretation
Negative Negative Without symptoms: Not suspected of having COVID-19 now or previously.
Vulnerable to COVID-19 infection!

With symptoms: Possible active COVID-19 infection.
Strongly recommend consultation with medical professional. Recommended nasal swab (PCR) test.
Positive Negative Without symptoms: Possible asymptomatic COVID-19 carrier. Active or recent COVID-19 infection. Likely to be infectious. Recommend isolation for 2 weeks. Please discuss nasal swab (PCR) test with medical provider.
Positive Positive With symptoms: Active or recent COVID-19 infection. Likely to be infectious. Recommend isolation for 3 weeks (4 weeks if hospitalized) from date of first symptoms. Recommend nasal swab (PCR) test.
Negative Positive Without symptoms: Likely to have had COVID-19 previously. Please continue to respect social distancing as well as local and federal hand hygiene and mask recommendations.

With symptoms: Consider additional illness such as pneumonia, flu, etc. Likely to have had COVID-19 previously. Strongly recommend consultation with a medical professional. Consider nasal swab (PCR) test. Recommend isolation for 2 weeks (4 weeks if hospitalized) from date of first symptoms.

What do my results mean?

As your isolation comes to an end, please be aware that it is critical to continue social distancing (6ft), and personal PPE use (mask and gloves) in public to help protect others at risk.

The listed recommended self-quarantine times are based on review of medical literature and are more conservative than CDC recommendation. If you are initially asymptomatic but develop symptoms, please see a medical provider for consideration of nasal swab (PCR) testing. We believe this is the best way to keep our community safe and healthy. Please consult your primary care provider for further recommendations.

At any point if you feel significantly short of breath, very weak, confused, have chest pain, or if you have any other concerning symptoms please go to the ER right away or call 911.

Patient Awareness and

This is a complimentary community study. As we are launching this project, this antibody test is NOT approved by the FDA, but that may change. We will continue to update the people of Blaine County as new rules and regulations are created.

This test is NOT a substitute for clinical judgement.

Patient Consent Statement

By my participation in this study I authorize healthcare personnel to digitally share with me my results for my own records. I consent to means of non-secure communication (personal email/text) for communication to me about my results.

I understand that COVID19 is a reportable disease to the Department of Health and Welfare and that my results may be shared with public health officials monitoring COVID19. I authorize my annonymous demographic data to be shared for research purposes only.

I understand that IgM-IgG antibody results for SARS-CoV-2 cannot do any of the following:
- rule-out an acute infection
- discern infectivity
- confirm immunity to re-infection

Regardless of results, the following safety measures should continue until a mass public vaccination program is established and in place and Centers for Disease Control officials declare the COVID19 pandemic resolved: social distancing, frequent hand washing, avoiding touching one’s face, wearing face masks.

• This test does not guarantee immunity in the short or long term but reflects likelihood of prior exposure.
• Detection of IgM or IgG antibodies does not determine end of self-quarantine; rather, the recommendation is based on time from symptom onset.
• Negative results do not rule out SARS-CoV-2 infection, particularly in those who have been in contact with the virus. Additional evaluation by medical practitioners and further testing should be considered to rule out infection in these individuals.
• Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status.
• Positive antibody results may be due to past or present infection with other related viruses. Though this is unlikely, further studies are needed to confirm it’s accuracy.
• It is not known whether persons having antibodies to SARS-CoV-2 are not infectious, can be re-infected, or may experience COVID-19 in the future.
