Do I need an appointment for a drug test or blood draw in Marshall?
No. Walk-ins are welcome at our Marshall clinic during business hours for most drug tests and blood draws. We recommend booking ahead for DNA paternity tests, since all parties must be present, and for mobile collection so we can schedule a collector to come to you.
