It is important to note that Medina Healthcare System is not a drive through testing site.

To receive a COVID-19 test at the Medina Healthcare System, it will require a visit with a provider and a provider’s order.

If a physician's order is obtained, the following COVID-19 tests are available through our laboratory:

Molecular Testing:

We are proud to announce that the Medina Healthcare System has purchased a molecular testing unit for the hospital that will test to the highest level of specificity for COVID-19. This unit will be used for patients that present with severe symptoms and have a risk of hospitalization. The Polymerase Chain Reaction test is currently the gold standard for testing for COVID-19 and we are happy to offer this service to qualifying patients.

Antigen Testing:

We now offer the rapid diagnostic test known as antigen testing at all Rural Health Clinic locations with a provider order. This convenient test is completed with a nasal swab and results are available in about an hour. The antigen test detects the presence of the virus when a patient is most infectious. You may be asked to take this test for secondary confirmation or your provider may order a molecular test based on your results and symptoms.

Antibody Testing:

Medina Healthcare System possesses the capabilities to accurately test for antibodies related to COVID-19. This antibody test will be completed through the system’s molecular testing unit in the hospital lab and will provide accurate results related to antibodies. As has been noted in the news, knowing whether one has recovered from COVID-19 is almost as important as knowing if one has it. The antibody test assists in the ability to know a patient’s status, assists researchers in understanding the disease prevalence, to include why some people are more severely impacted than others. This test also provides determination of whether one is a candidate for convalescent plasma therapy or can assist in the development of a future vaccine.

Planning for Flu Season:

The most important thing one can do when planning for the upcoming flu season is to have a flu shot. The Medina Healthcare System will begin offering flu vaccines for all ages on September 15th and established patients can walk in for a flu shot during office hours. Follow Medina Healthcare System on Facebook for updates, or visit the website for information related to services provided.
