Drug testing before work, after work and on weekends

A drug test during business hours usually means time off work. Colligo Pro's Southfield location is open outside them, early on weekday mornings, in the evening, and on weekend and holiday mornings.

Farmington Hills address, hours and directions

Southfield is closed in the middle of the weekday, and Farmington Hills covers that time. Between the two, a Colligo Pro location is open in the early morning, at midday and in the evening on weekdays. On weekends and holidays, Southfield is open in the morning and Farmington Hills is closed.

Both locations take walk-ins with no appointment, and parking is free at both. At Southfield, GPS brings you to what looks like the back of the building. That is the entrance, and the Colligo Pro sign is on the door.

For employers

If you send applicants or employees for a drug or alcohol test, these hours let a person with a daytime shift test before or after work, so the test does not cost you a shift. Tell the person three things.

  • Which location to use, with a link to its page, Southfield or Farmington Hills.
  • To bring a photo ID and any paperwork you give them, plus cash with exact change. Colligo Pro takes cash only.
  • That they can walk in during the location's hours, and call 248-757-5570 with any questions.

A visit usually takes about 15 minutes. For a rapid test, the person leaves with a printed result form to bring back to you.

To set up testing for your company, see testing for employers or call 248-757-5570.

For anyone who works days

If you need a test for yourself and work a day shift, Southfield's early morning and evening hours, and its weekend and holiday mornings, let you test without taking time off. Plan around the midday closure. You can walk in with no appointment. Call 248-757-5570 first if you are not sure your test is one Colligo Pro collects. There is more at testing for individuals.

Which tests

Colligo Pro collects urine drug tests and breath alcohol tests. If you were asked for a different kind of test, call before you come.
