PROFESSIONAL CO-OP, an original model for laboratory testing, launched in 2001 to support clinicians in all walks of medicine. PCS provides appropriately licensed clinicians with access to major lab services for a fraction of the typical costs with service that exceeds expectations. PCS does not solicit or enable unlicensed/unqualified people to sell diagnostic testing. PCS does not engage in the sale of products to treat patients based on laboratory findings, including findings based on altered reference ranges. There are no fees to join and no minimums. Our staff is knowledgeable, professional, and experienced in handling the issues and problems commonly seen in laboratory testing. PCS allows the clinician to focus on what's most important, patient care!
