Corona Virus Testing in Carrollton:
RealTime Laboratories provides both RT-PCR tests and Antibody tests for COVID-19 at our laboratory in Carrollton. We offer convenient drive-up appointments, and you can stay in your car while your sample is collected.
It is important to know which test you are ordering and for what purpose. For example, travelers to international destinations (and select states in the US) are required to present a negative COVID-19 test result on arrival.
Governments across the globe are continually updating their travel policies. Please visit the US Secretary of State’s website for the latest information: https://travel.state.gov/content/travel/en/traveladvisories/COVID-19-Country-Specific-Information.html
For most travel-required testing, only the RT-PCR test is acceptable. Our RT-PCR test uses the TaqPath COVID-19 Combo Kit from Thermo-Fisher. It is performed under EUA and accepted globally. (Travelers to China, please click here for important information)
