DISA has added online check-in functionality for all Texas area facilities, with plans to expand to all DISA owned service centers.

While walk-ins are always welcome, you can now save time by reserving your place in line with DISA’s new ‘check-in online’ feature.

How does it work?

Upon notification that your employee is due for a drug test, your designated employee representative (DER) can use the link below and reserve their place in line.

When using the Online Check-In system, minimal information is required to check in, but we do ask for a phone number (either DER or Donor). Prior to you being at the ‘front of the line,’ you will receive a text messages with updates and a reminder when it’s time to head over.

By checking in online, chances are you'll be next or almost next in line as soon as you arrive. Please note that during peak hours/peak season your wait time may be longer.
