Precision Specimen Group is Miami's trusted partner for professional specimen collection. We function exclusively as a collection site, specializing in mobile and on-site collections for DOT, Non-DOT, and DNA testing.  We are dedicated experts in secure and reliable specimen collection, focused purely on maintaining the highest standard of Chain of Custody logistics. 

​

We do not analyze specimens; we perfect the initial collection, ensuring every sample, from DOT screenings to legal DNA swabs, is collected with absolute integrity. Our unique Hybrid Collection Model gives you the best of both worlds:  suite access for walk-ins and our mobile collection fleet for on-site convenience.  Our certified professionals use rigorous protocols, security, and seamless logistics to bridge the critical gap between collection and lab processing, confidently.

Whether you're a DOT-regulated employer needing fleet compliance or an individual requiring legal relationship testing, we provide the absolute confidence your chain of custody requires.
