DOT testingCompany-policy testing for employers who are not federally regulated. You set the panel and the policy; we handle the collection, the paperwork and the custody trail, on your site and on your schedule.
Workplace testingBlood draws performed by a registered nurse, at our office, your clinic or the patient's home. Built for practices and staffing agencies that need reliable overflow capacity without adding headcount. You can also order your own lab tests through us.

DNA testingMost of our work is for employers who need a collection done without losing half a day to it.
Individuals are welcome too — walk in to the office, or book a time for a collection, a draw or a DNA test arranged privately.
Booking takes a couple of minutes. Most appointments are confirmed the same day.
Call, book online, or walk in during office hours. Say what kind of collection it is, how many people, and whether you are coming to us or we are coming to you. If you are not sure which test applies, say so — we will work it out with you.
For mobile visits you get a confirmed arrival window, usually the same day. Evenings and weekends are available by appointment.
At the office, everything is ready when you arrive. On a mobile visit, everything needed arrives with us — your site needs no preparation beyond a private space.
Specimens go to the laboratory with the chain of custody complete. Regulated results are released through a Medical Review Officer, as the regulations require.
