Contact Us

We work hard to make sure you’re happy! A laboratory can be challenging to interact with, and we are working hard to change the standard of service for labs. We decided early on to never allow a computer to answer the phone! When you contact our lab, you will be connected immediately to a service-minded professional who will work hard to ensure all of your needs are met. What drives us here is the simple fact that we know we’re dealing with people’s health, and we believe strongly that patients deserve solid answers and for labs to make things easier, not difficult.

Feel free to ask for details, don't save any questions!
