Streck
Developer and manufacturer of stabilized clinical sample matrices, external quality-control materials and verification kits for clinical laboratories and diagnostic developers. Core activities include formulation of stabilized whole-blood and molecular control materials, assayed multi-parameter controls for hematology and flow cytometry, full-process molecular controls and verification kits in patient-like matrices (room-temperature stable), lot-specific assay documentation and an interlaboratory peer-group benchmarking platform. The company supplies both research-use verification kits and platform- or panel-specific full-process controls, including products cleared for use with specific multiplex pathogen detection panels.

Products
Multi-parameter procedural flow cytometry control (assayed, patient-like matrix)
Ready-to-use positive procedural control assayed for multiple immunophenotyping parameters, available in multiple clinically relevant levels and containing defined subpopulations; formulated to resemble whole blood and challenge the entire flow cytometry preparation and analysis workflow.
CD34 enumeration control (tri-level, patient-like matrix)
Ready-to-use positive procedural whole-blood control designed for enumeration of CD34+ cells, provided in a tri-level format to monitor performance across clinically relevant CD34 concentrations without dilution and with extended open/closed-vial stability.
Targeted flow cytometry control for selected markers including intracellular antigens
Whole-blood control assayed for a subset of CD markers including intracellular targets; designed to represent normal peripheral blood leukocytes and compatible with automated sample preparation instruments.
Blood culture gram-positive verification kit (RUO) — single-use patient-like tubes
Single-use verification kit in a patient-like matrix containing inactivated microorganisms and blood components intended for verification of molecular workflows that detect gram-positive bacteria and for operator training; packaged as positive and negative single-use tubes.
Blood culture yeast verification kit (RUO) — single-use patient-like tubes
Verification kit supplied as single-use positive and negative vials containing inactivated yeast targets in a stabilized blood-like matrix for verification of molecular workflows and operator training; room-temperature stable and intended for research and verification use.
Full-process molecular control for blood-culture identification panel (IVD-cleared for specific panel)
Patient-like full-process control designed to validate the entire analytical process of a blood-culture identification multiplex panel, covering the panel's bacterial, yeast and antimicrobial-resistance targets; provided in single-use vials and intended to be handled like a positive patient sample. Available in formats validated for use on compatible automated multiplex PCR systems and in platform-agnostic RUO formats.
