UNSPSC 41131502: Automated differential cell counter

In this classification, an automated differential cell counter is a device used to identify one or more of the formed elements of the blood. The device may also have the capability to flag, count, or classify immature or abnormal hematopoietic cells of the blood, bone marrow, or other body fluids. US FDA regulates Automated differential cell counter under 21 CFR 864.5220 and under FDA product code GKZ.

UNSPSC 41131502 Automated differential cell counter is a Commodity code that covers laboratory analyzers and consumables for blood and hematology testing, including hemoglobin analysis systems, proficiency testing samples, and ion-exchange HPLC analyzers used in clinical screening and quality assurance applications. State and local buyers under this code span public health agencies, university research and testing facilities, and state departments of health services. The work actually being solicited includes procurement of capital equipment such as hemoglobin testing systems with automated sample loaders, replacement laboratory instruments for aging equipment, and specialized consumables and supplies for existing instruments — reflecting a mix of capital equipment replacement and ongoing consumables replenishment to support blood analysis and screening operations.

Activity concentrates in Texas and Wisconsin based on recent opportunities. The Texas Health and Human Services Commission (HHSC) and Department of State Health Services (DSHS) are the most active buyers under this code, having posted two competitive IFBs in the past three months: HHS0017310 in May 2026 for a D-10 Hemoglobin Testing System with Rack Loader for the South Texas Lab in Harlingen (response deadline May 18, 2026, with historical spend guidance of $45,050 to $80,000), and HHS0017071 in March 2026 for PerkinElmer ICP-MS consumables and supplies supporting pediatric lead screening (response deadline March 5, 2026, historical spend $20,000 to $30,000). The University of Wisconsin-Madison issued RFB 2026-UWMSN-01287 in April 2026 for custom-made hematology and whole blood chemistry proficiency testing samples through its ShopUW+ portal (response deadline April 21, 2026). All three opportunities are open competitive procurements with no specific set-aside designations; HHSC documents encourage but do not require HUB subcontracting plans.
