Rapid Antigen Tests

We can now perform the Sofia SARS Antigen FIA test, a type of rapid antigen test that offers quick, same-day results. This test is performed by swabbing your nose for a fluid sample to determine if the sample contains proteins found on the surface of the coronavirus. We recommend this test if you are currently experiencing symptoms consistent with those of COVID-19, such as cough, fever, breathing issues, sore throat, gastrointestinal distress, body aches, fatigue, headache, or recent loss of taste/smell. Results of this test are most accurate when the test is administered within 1-5 days after symptom onset.

Viral PCR Tests

This nasal swab test looks for evidence of an active viral infection. A PCR test is a good choice if you’ve been exposed to COVID-19, but do not currently have symptoms. It is also the recommended COVID-19 test for travel, school, or return-to-work purposes. The swab PCR test detects genetic material of the virus. Please understand that PCR fluid samples are sent out to a lab, and turnaround times for your results may vary.

Please Note: We are an urgent care center with the ability to provide COVID-19 testing. We are NOT an Illinois Community-Based Testing Site. If you are looking for a drive-through testing location, or are uninsured in search of a free test, please check the IDPH website.

Saliva PCR test for Kids

Saliva tests are more comfortable than nasal swabs and just as accurate. The saliva test looks for evidence of an active viral infection by detecting genetic material of the virus. You will spit several times into a tube and then screw on the cap to complete the test. Due to limited quantities, we are generally reserving saliva tests for children returning to school or in need of a COVID-19 test. Results available within a few days. Learn more »

Understanding COVID-19

COVID-19 is a new virus strain that has only spread in people since December 2019. It belongs to the same family of virus as the common cold, SARS and MERS. However, it seems to be more contagious than these related coronaviruses. According to current evidence, COVID-19 virus primarily spreads through airborne respiratory droplets and close contact.

Reported cases of COVID-19 range from mild illness to severe pneumonia that requires hospitalization. Older adults and immunosuppressed persons are at higher risk of complications. Some carriers experience no symptoms at all.

There is no specific antiviral treatment recommended at this time, though supportive care can help relieve symptoms. In the past year, medical teams and researchers have developed new vaccines to protect against Covid. Right now, supplies are limited, but production and availability will increase over the spring. The goal is for everyone to be able to easily get vaccinated against COVID-19 as soon as large enough quantities are available. Until then, we will need to utilize wide-spread testing, quarantines, and social distancing to stop this pandemic.
