COVID-19 Antibody Testing

Madelia Health is offering Coronavirus Antibody Testing for $100 via direct access (patient pays before testing). The blood test is to see if you have had COVID-19 previously, NOT to see if you currently have an infection.

Those who use an antibody test need to understand its limitations. Here is what you need to know prior to testing:

  • Testing should be done at least three weeks after all COVID-19 symptoms have resolved. It can take up to three weeks for antibodies to show up after infection, longer if you are immunosuppressed.
  • Antibody tests may be positive if you have been vaccinated for COVID-19.

  • False positives could mean that you have had another coronavirus infection, but not necessarily COVID-19.
  • Research is still ongoing as to whether a positive test means that you have immunity to COVID-19.
  • It may be necessary for some patients to have two tests to generate reliable results.
Drawing Blood

To be tested, please call the Clinic for an appointment with our lab at (507) 642-5200. Test results will be mailed to the patient and can take several days to process.
