The University of Wisconsin-Madison issued RFB 2026-UWMSN-01287 (posted April 3, 2026, due May 5, 2026 via ShopUW+ portal) for custom-made Hematology/Whole Blood Chemistry Proficiency Testing Samples. Texas HHSC has signaled historical annual spend of $20,000 to $80,000 for similar goods in fiscal year 2025. All three recent opportunities carry open competitive procurement with no explicit disadvantaged-enterprise set-asides; Texas solicitations request firm and fixed pricing and require Exhibit A affirmations and specific Texas statutory certifications (abortion funding limitations, firearm discrimination, energy company boycotts, Israel boycotts).
