I have enjoyed our collaboration with Genesys as our team member testing partner. This has been a tremendous undertaking on both sides and we have worked through it TOGETHER. Their responsiveness is superb, communication is excellent and when we have had some issues arise, they take ownership and rectify expediently - that is the measure of a well-run organization.

I had an excellent experience with GDI Labs, they have competent pathologists that are highly competent with toxicology, UTI and CoVID lab testing. Their responsiveness and attention to detail is highly exceptional. They have a great staff that answered all my questions. Highly recommend testing and partnering with the lab. Thank you guys!
