I've gone the the drive thru site a couple times. The young lady that has been there has been very sweet, helpful and very professional. Even when the car is front of me was extremely rude. She did amazing. Anyways, I received my results in fairly quick time and I appreciate what they are doing.

They are so sweet. There was a mess up with my son's dr and a covid test for a procedure and they made sure I had it in time so we didn't have to reschedule. So very thankful for one of the young ladies that work there.

Advanced Lab Services has professional staff that excel at providing quality COVID-19 testing. Their drive-up testing is fast, and it's super simple to schedule testing on their website. 5 out of 5 stars, for sure.

I came here to take a covid test for travel. This is by far the best experience I have ever had anywhere. The staff here is amazing. So friendly and efficient. You can get scheduled the same day, take the test in 5 minutes and get your results back same day or next morning at the latest! Also, she knew my situation and personally called me to tell me my results with in my email. I cannot recommend them enough.

A huge thank you to Timothy McClure and the entire staff at Advanced Laboratories. You are all making it possible for us to take immediate action in slowing the spread during this pandemic. As an essential worker myself, I have witnessed first hand day in and day out, the swift and professional service provided to those in the Texoma Area by this team. Service with a smile behind those masks is all one can ask for. Thank you for showing up for work everyday. I’m sure it can’t always be easy, but thank you. We see you!!

This was our 2nd time using advanced lab for covid testing before international flights. These guys answer the phone and return email quickly.....which is important if your planning to cross the globe tomorrow. Super fast service. Our results have come back within 8 hours or less both times.

Jason Y.

Covid test is super fast. Mostly cause they have a lab there, instead of having to send it to like Dallas. PCR test at that. I've waited about 4hrs and boom had my results.

Carl E.

Teresa D.

Covid 19 testing drive thru, super fast and got the results back within about 4 hrs. I recommend scheduling appt in advance for sure.

Important Update

The COVID-19 Public Health Emergency declaration ends May 11th, 2023. That means insurance companies will no longer be required to waive costs or provide free COVID-19 tests. 

ALS will continue to provide COVID-19 testing for our community through our drive-through, however we will not be able to accept insurance. As of May 12th, 2023 we are only accepting cash and card payments. 

Please feel free to contact us if you have any questions!
