Corona Virus (SARS-CoV-2)-19 Testing Info
SARS-CoV-2 Antibody Testing:
- The test being offered is a blood test that checks for SARS-CoV-2 virus antibodies. . This test checks for IGM antibodies and IGG antibodies. Antibody tests check for your body’s response to a virus not the virus itself.
- A negative test does not mean you do not have SARS-CoV-2 as it may take several days for your body to make antibodies against the virus.
- A positive test may indicate, you either have SARS-CoV-2 or are recovering from it. A positive IGG test does not mean you are immune. All CDC guidelines (including city, state, and national quarantine and Shelter-in-Place guidelines) must still be followed.
- Please be aware that ONLY the test is being offered at this time, NOT medical treatment.
- If your test is negative but you are still having symptoms or your test is positive we recommend you follow up with a physician to determine if any other medical interventions are indicate. Current recommendation is to get a PCR (nasopharyngeal swab) test done if the antibody test is positive or you are having symptoms. This can be done through the clinic or physician of your choice. (limitations of testing supplies may make this difficult.)
- This test has not been reviewed by the FDA but is being offered under the FDA’s Policy for Diagnostic Tests for Coronavirus Disease –2019, Section IV.D
- Negative results do not rule out SARS-CoV-2 infections, particularly in those who have been in contact with the virus. Follow-up testing with a molecular diagnostic 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.
- Early infections may not have generated a sufficient antibody response to be positive on the test.
- There is a 13% false negative rate. (This means that out of 100 people with the disease 13 will test negative.
- Currently it is not known if having IGG antibodies indicates immunity; however, having IGG antibodies does indicate having had the infection.
- Positive results may be due to a past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43 or 229E
What the test results mean

|Positive||Negative||Indicates an acute infection, it is not clear if patients are contagious.CDC recommendation is that people with positive tests or negative tests with symptoms can end quarantine when they have had 72 hours fever free with no fever reducers, symptoms including cough are resolved and it has been at least 7 days since the symptoms started.|
|Positive||Positive||Indicates a convalescent (recovering) stateIf people with these results are having any symptoms the quarantine recommendations apply.|
|Negative||Positive||Indicates a previous infection|
If you are having worsening of symptoms or SOB, you should call 911 or go to the nearest ER.
