Professional Toxicology Services Inc.

Professional Toxicology Services Inc., a woman-owned small business based in Overland Park, Kansas, provides blind drug-testing quality assurance samples to the U.S. Customs and Border Protection (CBP) as a prime contractor under a single-award IDIQ vehicle, operating exclusively in the full-and-open category across its federal footprint. The firm holds SBA certifications as a small disadvantaged business and woman-owned small business, with a manufacturer-of-goods designation reflecting its production and supply of DEA-registered exempt chemical preparations and blind urine specimens (categorized as negative, positive, and adulterated or substituted) used to verify the accuracy of CBP's designated drug testing laboratories under the agency's Drug-Free Workplace Program.

Professional Toxicology Services has a completely concentrated customer base: all 15 awards in the source data derive from CBP, accounting for $446 thousand in combined potential value. The vendor operates under a $36 thousand single-award IDIQ contract (70B06C22D00000004) awarded in January 2022 as a total small business set-aside, from which CBP has issued ten task orders ranging from $1.7 thousand to $7.5 thousand. A second parent vehicle, Indefinite Delivery Contract HSBP1017D00007, carries three task orders worth $210 thousand combined potential value. Recent work includes a $1.7 thousand delivery order awarded January 2026 for workplace drug testing quality assurance services with performance in Shawnee, Kansas; a $7.5 thousand delivery order for workforce quality assurance drug testing issued the same date; and multiple option-year exercises across both IDIQ vehicles supporting pre-employment and employee drug testing initiatives at CBP locations in Washington, D.C. and Minneapolis, Minnesota.

The award trajectory is flat to declining. Awards per year averaged roughly two to three from 2022 through 2026, with no growth trajectory evident. Only two awards complete within the next twenty-four months, carrying $9 thousand in combined potential value and presenting limited recompete exposure. Across all 15 awards, only $73 thousand has been obligated against the $446 thousand potential value, suggesting task orders are issued and drawn down incrementally rather than awarded at full ceiling. All work is categorized under NAICS Medical Laboratories and PSC Reference Laboratory Testing. The vendor performs no subcontract work and maintains an exclusively domestic posture, with no vehicle participation outside its two CBP-specific IDIQs.
