Streck

What Streck does

Streck is a privately held biotechnology company founded in 1971 and headquartered in La Vista, Nebraska, with between 251 and 500 employees. The company develops and manufactures clinical laboratory quality control products and sample stabilization solutions built on a proprietary cell stabilization technology that preserves human blood cells at room temperature with extended closed-vial stability of up to 190 days for hematology controls and 90+ days for flow cytometry controls.

The product portfolio is organized across four disciplines: Hematology QC (Para 12 Extend, Para 12 Plus, Retic-Chex Linearity for BC, STaK-Chex Plus Retics), Flow Cytometry QC (the CD-Chex family including the May 2025-launched CD-Chex Daily with 51 assayed markers, CD-Chex Plus, CD-Chex CD34, CD-Chex CD103 Plus, CD-Chex CD117 Plus, CD-Chex TdT Plus, CD-Chex Select), Molecular Diagnostics QC (the MDx-Chex line validated across BIOFIRE FilmArray, Luminex VERIGENE, and LIAISON PLEX platforms for blood culture, respiratory, STI, and vaginitis panels, plus ARM-D antibiotic resistance kits and Blood Culture Verification Kits), and Specialized Testing (A1c-Cellular). A separate Sample Stabilization business supplies blood collection tubes (Cell-Free DNA BCT, Cyto-Chex BCT, Nucleic Acid BCT, Nucleic Acid Plus BCT) and reagents for liquid biopsy, immunophenotyping, and CNS applications. Supporting services include the free STATS interlaboratory quality comparison program and a Pipette Verification Service.

Streck's revenue model is consumables-driven: one-time unit sales of QC products and blood collection tubes to clinical laboratories, supplemented by recurring engagement through STATS (which is free but locks customers into peer-group benchmarking using Streck controls) and a small professional services line for pipette calibration. Distribution combines direct online ordering and quote-based sales for US/EU customers, an international distributor network for global reach, and strategic embedded partnerships with major diagnostic instrument manufacturers — BD Biosciences, Beckman Coulter, Abbott, Sysmex, Luminex, and bioMerieux — that incorporate Streck QC into their customer workflows. The company holds multiple FDA Class II clearances and IVDR EU Declarations of Conformity, positioning it as the standard third-party QC layer across the major clinical hematology and flow cytometry platforms. Leadership comprises founder Wayne Ryan and Chief Operating Officer John Noble; ownership is private with no disclosed venture capital, private equity, or parent company affiliation.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Bio-Rad Laboratories: Bio-Rad is a diversified life science and clinical diagnostics company that offers third-party QC controls for hematology, immunology, and molecular diagnostics — directly competing with Streck's core QC portfolio while also serving broader research and clinical lab markets.
• BD Biosciences: BD Biosciences is a major flow cytometry instrument manufacturer and a Streck partner, but also sells its own application reagents and could vertically integrate into QC controls, making it both a partner and a structural competitive threat.
• Beckman Coulter: Beckman Coulter is a leading hematology analyzer manufacturer and Streck partner. While it purchases Streck controls for its own platforms, Beckman Coulter is part of Danaher and could develop competing QC solutions through its broader diagnostics portfolio.
• Sysmex: Sysmex is a global hematology leader whose CEO publicly endorsed the Streck partnership. It represents both a key partnership customer and a competitive risk if Sysmex chose to develop proprietary controls for its installed base.
• Abbott Diagnostics: Abbott Diagnostics is a major hematology platform provider (CELL-DYN) and molecular diagnostics player. It validates Streck controls for its platforms but is a large diversified diagnostics competitor with the resources to enter QC directly.
• Roche Diagnostics: Roche Diagnostics is the largest global IVD player, offering broad QC, hematology, and molecular diagnostics products. Its scale and global reach create competitive pressure on niche QC specialists like Streck in enterprise lab accounts.
• Siemens Healthineers: Siemens Healthineers is a major hematology analyzer manufacturer and broader IVD player. Its scale across imaging, diagnostics, and laboratory solutions makes it both a Streck-compatible platform partner and a broad competitive threat.
• Thermo Fisher Scientific: Thermo Fisher is a global life sciences and diagnostics leader offering laboratory controls, reagents, and instruments. Its scale, R&D budget, and acquisition history make it a long-term competitive risk in the clinical QC space Streck occupies.
• Hologic: Hologic is a diagnostics and women's health company whose molecular diagnostic instruments represent an adjacent competitive threat. As Streck expands MDx-Chex into vaginitis and STI panels, Hologic's Panther systems become a relevant comparison for QC validation customers.

Emerging players

• DiaSorin: DiaSorin is an IVD company focused on specialty diagnostics and molecular testing. Its LIAISON platform partnership with Streck (MDx-Chex for BCN/BCP/BCY) makes it a peer-and-partner comparable for blood culture molecular QC adjacencies.
