Free drive-through COVID-19 testing clinics will be available to Collin County residents May 20 in McKinney and May 21 in Plano.

The state-run testing program is expected to return to other areas of Collin County on a rotating basis every two weeks, according to a May 14 release from Collin County. These testing sites have been put together through the collaboration of the Texas Military Department, North Central Texas Trauma Regional Advisory Council, Texas Department of Emergency Management, Collin County, Collin College and the city of Plano, the release said.

The tests will be administered by appointment only, and people must register at least 24 hours before the test dates by calling 512-883-2400 or by registering online. There will be a limit of 100 tests for each date, the release said.

In order to receive a test, residents must have one or more symptoms of the virus. Symptoms include fever, chills, cough, fatigue, body or muscle aches, joint pain, shortness of breath, sore throat, headaches, nausea and vomiting, nasal congestion and loss of taste or smell.

On May 20 testing will be held at the Russell A. Steindam Courts Building parking lot, 2100 Bloomdale Road, McKinney. On May 21 testing will be available at the Collin College Spring Creek Campus, 2800 E. Spring Creek Parkway, Plano. Testing will be available from 10 a.m.-4 p.m. on both days.
