Dozens of walk-in and drive-thru COVID-19 testing locations remain open to Montgomery County residents seeking tests for the disease.

While the county's free testing voucher program for residents ended earlier this month, clinics and other businesses from Willis to The Woodlands are offering both molecular tests to diagnose active COVID-19 cases as well as antibody tests used to identify previous infection.

Based on information from the Texas Department of State Health Services, both types of test are available throughout the county both for walk-in patients and on an appointment basis. Some locations may require a physician's referral for registration, and a deductible, copay or co-insurance may apply.

Operational walk-in and drive-thru testing sites confirmed by the state health department as of Nov. 22 are identified below, with those requiring an appointment listed in red and those not requiring appointments listed in gray. The department recommends calling testing sites to confirm costs, the type of test offered and availability before scheduling a test.

The county has reported more than 2,000 new COVID-19 cases in November alone and surpassed 16,000 cumulative cases reported Nov. 23. Montgomery County's active case count also passed the highest mark since late July this week.
