If you are an existing patient at the Lower Sioux Health Care Center, please call the clinic reception desk at: 697-8600. Please state you are an existing patient and would like to be tested on July 1st during the testing event. The testing hours are 8 a.m. to 4 p.m. We are not accepting appointments; this is a drive-up event only. There will be 2 lanes, one for pre-registered patients and one for non-registered patients. Pre-registering will expedite the process for you and testing should take less than 10 minutes.
