Priority Diagnostics Inc was founded with a single mission: to make professional drug testing accessible, convenient, and reliable for every employer and individual in Southern California.
We recognized that traditional drug testing clinics created unnecessary burdens for businesses — sending employees off-site disrupts productivity, introduces delays, and adds logistical headaches. Our solution was simple: bring the certified collection directly to you.
Today, Priority Diagnostics Inc operates as a trusted mobile drug testing and specimen collection provider across San Diego and Orange County. We serve a wide range of clients — from small businesses and independent contractors to large corporations and government agencies — delivering the same high standard of care, compliance, and professionalism at every collection.
