Collection Network

DFSI has built a diverse global network of sample collection personnel to serve the needs of our anti-doping and healthcare clients. We can offer our clients access to a collection network with over 500 collectors covering more than 100 countries. 

Doping Control Officers (DCOs) are center stage in the sample collection processes and are responsible for the securing of specimens (urine, blood, saliva) from athletes in order to ensure fair play. This network is highly trained to follow our clients’ policies and ensure the integrity of over 100,000 steroid and drugs of abuse samples collected annually. DFSI values their important role in tactfully leading anti-doping procedures for sports organizations worldwide. 

Our healthcare network of professionally trained phlebotomists, laboratory technicians, registered nurses and other medical professionals are devoted to providing the highest levels of patient care, quality collections, and client service whether it’s in your office or in your home.
