Bio-Synthesis, Inc. has one of the biggest DNA sample collection networks in the world. Our existence in most cities allows us to schedule appointments near your home or office, often the same week. Tested parties may make collective appointments or appointments separately at no extra cost, even if they are in separate states. 

Below is a list of cities in Illinois where we have well-known DNA sample collection facilities. If you can not access one for whatever reason, we also have an extensive mobile collection network that can travel to you. For more information or to schedule a collection appointment, please call 1-800-DNA-EXAM (800-362-3926).
