UNSPSC 41116158: Enzyme linked immunosorbent assay ELISA kit

A test kit that uses antibodies and color change to identify a substance

UNSPSC 41116158 Enzyme linked immunosorbent assay ELISA kit is a Commodity code under which state and local governments procure specialized laboratory diagnostic equipment, consumables, and supplies for clinical testing and quality assurance. Recent opportunities show that state and local buyers are acquiring hemoglobin testing systems with automated sample-handling capability, proficiency testing samples for hematology and blood chemistry procedures, and ICP-MS consumables and supplies for pediatric blood lead screening. The Texas Health and Human Services Commission and Department of State Health Services emerge as repeat buyers, issuing multiple invitations for bids to stock replacement and consumable laboratory equipment across their testing facilities. Higher-education institutions also participate, as evidenced by the University of Wisconsin-Madison's procurement of custom-made proficiency testing samples. Most solicitations are issued as Invitations for Bids with firm, fixed pricing and best-value award criteria favoring vendor qualifications and delivery performance alongside price.

Recent activity centers in Texas and Wisconsin. The Texas Health and Human Services Commission posted two invitations for bids in March and May 2026 — solicitation HHS0017071 for PerkinElmer ICP-MS consumables and supplies (response deadline March 5, 2026) and solicitation HHS0017310 for a D-10 Hemoglobin Testing System with Rack Loader to replace equipment at the South Texas Lab in Harlingen (response deadline May 18, 2026), with historical spend guidance of $20,000 to $30,000 and $45,050 to $80,000 respectively for fiscal year 2025. The University of Wisconsin-Madison's ShopUW+ event 2026-UWMSN-01287-RFB solicited custom-made hematology and whole blood chemistry proficiency testing samples with a response deadline of May 5, 2026. Neither state-level solicitation included set-aside designations, though HUB subcontracting plans were encouraged but not required in the Texas procurements. All three opportunities specify submission of executed exhibits, compliance certifications, and adherence to applicable state and federal regulatory requirements including suspension and debarment verification, E-Verify compliance, and data security controls.
