About the company
Vector Test Systems, Inc., doing business as Vector Test Systems, manufactures diagnostic test kits for vector-borne and infectious diseases and sells them to the Defense Logistics Agency and the Department of the Army as a prime contractor operating entirely on full-and-open, competitive purchase orders with no set-aside designation. The company is a minority-owned, Subcontinent Asian American-owned small disadvantaged business based in Thousand Oaks, California, structured as a Subchapter S corporation.
Vector Test Systems' federal work consists almost entirely of manufacturing and delivering malaria detection, dengue antigen, West Nile virus, St. Louis encephalitis, Anaplasma, and Leishmania diagnostic test kits through the Medical Supply Chain funding mechanism. The company holds a dominant position as a sole-source supplier to Defense Logistics Agency Troop Support Medical, with 389 awards (96% of the company's recent prime footprint) for specialized diagnostic test kits valued at $1 million combined potential value. The remaining 15 awards come from the Department of the Army Medical Command, valued at $7.3 million combined potential value. Representative recent work includes a $1,520 firm fixed-price purchase order from DLA Troop Support Medical dated December 15, 2025, for dengue antigen test kits, a $3,040 order from the same customer dated April 21, 2025, for dengue antigen test kits, and a $6,720 order dated April 21, 2025, for West Nile virus, St. Louis encephalitis, and Anaplasma test kits. All work is performed at the company's Thousand Oaks facility.
The divergence between award count and dollar value is pronounced. DLA Troop Support Medical places the majority of orders by count but anchors only $1 million in combined potential value, while the Department of the Army Medical Command, with fewer than 4 percent of the award count, accounts for $7.3 million in combined potential value. The NAICS and PSC profile reflects pure manufacturing: 296 awards are coded to Family Planning Centers (a legacy NAICS classification for reproductive health supplies), 92 to Pharmaceutical Preparation Manufacturing, and 390 of 405 awards fall under the In Vitro Diagnostic Substances, Reagents, Test Kits And Sets PSC code.
Activity has contracted sharply. The company received 56 awards in 2022, 53 in 2023, then declined to 16 in 2024 and 20 in 2025. Only three awards appear in the 2026 pipeline as of the source date (July 15, 2026). Combined potential value across all 405 awards totals $8.3 million, though obligated dollars ($10.4 million) exceed potential value by 26 percent, indicating significant invoicing against smaller orders. The source data span from December 2003 onward, though award velocity has shifted markedly downward in the past eighteen months, suggesting either a shift in DLA procurement strategy, competitive displacement, or reduced demand for this category of diagnostic inventory.
