About the company
Diagnostic Laboratory of Oklahoma LLC Sales Dept Division, a subsidiary of Quest Diagnostics Incorporated, delivers clinical laboratory testing and pathology services to federal healthcare agencies as a prime contractor exclusively under full and open competition, with no set-aside participation. The company operates as a for-profit limited liability company headquartered in Oklahoma City, Oklahoma, competing across 47 awards (100% prime footprint) totaling $20.5 million in combined potential value. Diagnostic Laboratory of Oklahoma LLC does not subcontract; its entire federal footprint is prime work.
The vendor's customer concentration is heavily skewed toward the Indian Health Service, which accounts for 23 awards ($19.9 million combined potential value, 97% of the portfolio by dollars). The Department of Justice Bureau of Prisons Federal Correctional Institution El Reno represents the second-largest customer by award count (8 awards) but a distant second by dollars ($171 thousand), followed by the Department of the Army Oklahoma Army National Guard (4 awards, $257 thousand) and the Department of Justice Bureau of Prisons Federal Transfer Center Oklahoma City (5 awards, $26 thousand). This concentration disparity signals a customer portfolio dominated by a single large healthcare agency (IHS) with distributed smaller purchase-order relationships for inmate testing across correctional facilities.
Diagnostic Laboratory of Oklahoma LLC's primary vehicle is a $14.92 million single-award Indefinite Delivery Contract with IHS awarded November 6, 2025, with an ultimate completion date of February 28, 2027. Against this IDC, nine delivery orders totaling approximately $2.02 million have been issued across multiple Oklahoma and Kansas IHS facilities (Lawton, Anadarko, Wewoka, El Reno, Clinton, Pawnee, and Haskell Indian Nations University in Lawrence), with individual task orders ranging from $35 thousand to $900 thousand and completion dates extending through February 28, 2031. A companion single-award Blanket Purchase Agreement valued at $2 million (effective May 20, 2024, through May 20, 2025) supports laboratory and pathology services across the Oklahoma City Area Office. Ten BPA calls against this $2 million vehicle have been issued with individual ceiling values from $15 thousand to $300 thousand. The vendor also holds positions on two smaller vehicles: Blanket Purchase Agreement 75H71124A00030 (10 task orders, $747 thousand) and W912L616A0015 (2 task orders, $9 thousand) supporting Army National Guard and Bureau of Prisons work.
Capability focus is laboratory and pathology testing: 44 of 47 awards are classified under Medical Laboratories NAICS, with 42 mapped to the Reference Laboratory Testing PSC. Work encompasses medical laboratory testing, pathology analysis, COVID-19 testing, and clinical diagnostic support to IHS facilities serving American Indian and Alaska Native populations, plus inmate laboratory testing (regular and COVID-19) at Federal Correctional Institution El Reno and the Federal Transfer Center Oklahoma City. Representative delivery orders include a $900 thousand order to the Lawton, Oklahoma IHS facility (November 20, 2025), a $160 thousand order to the El Reno facility (December 3, 2025), a $125 thousand order to Haskell Indian Nations University (December 9, 2025), and an ongoing $24 thousand purchase order from Federal Correctional Institution El Reno for inmate lab testing (August 1, 2026).
Activity growth accelerated in 2024 (13 awards) after minimal volume in 2022–2023 (3 and 1 awards respectively), with 11 awards placed in 2025 and 1 in 2026. Two awards (combined potential value $184 thousand) face ultimate completion within the next twenty-four months and thus present recompete exposure. Combined dollars obligated across the portfolio total $3 million (15% of combined potential value), signaling that most work remains unfunded or partially funded. The vendor's parent, Quest Diagnostics Incorporated, is one of the nation's largest diagnostic testing providers and holds federal positions with the Department of Veterans Affairs and the Centers for Disease Control and Prevention, providing parent-level operational capacity and expertise supporting the subsidiary's IHS and Bureau of Prisons execution.
