Laboratory & Diagnostic Support

OHS provides onsite collection for a wide range of laboratory and diagnostic services, making employee testing simple, convenient, and efficient. We perform all blood draws, specimen collections, and screenings directly at your facility. Once collected, samples are sent to our certified partner laboratories for processing, and results are delivered quickly back to your HR, safety, or medical team.

This approach keeps employees onsite, reduces downtime, and ensures every test is handled with accuracy and professionalism.
