Streck Cell-Chex™

The Only Body Fluid Control With 5-Part White Cell Differential Capability:

Cell-Chex is a body fluid procedural control for red blood cell (RBC) and white blood cell (WBC) counts, crystal identification, and white blood cell differentiation. Cell-Chex is a spinal and body fluid control with distinct white blood cell and red blood cell populations for manual counts. When stained in the same manner as a patient sample, the white blood cells can be differentiated. The multi-level control is assayed for manual cell counts, the 5-part white blood cell differential, as well as the two-part polymorphonuclear and mononuclear differential. Level 1-UC contains urate crystals and Level 1-CC contains CPPD crystals to aid in identification of crystals in synovial fluid.

Streck Cell-Chex™ Auto

The First Automated Body Fluid Cell Count Control For Abbott, Beckman Coulter®, And Sysmex® Hematology Instruments:

Improve efficiency, maintain testing accuracy, and decrease turnaround times for most body fluid samples by eliminating the need for manual hemacytometer testing by one or more technologists.

Cell-Chex Auto is a three-level spinal and body fluid control for evaluating the accuracy and precision of hematology instruments that measure blood cell counts in patient body fluid samples. Cell-Chex Auto is packaged in a plastic 3.0ml vial with a pierceable cap. The assay provides total red blood cell (RBC) and white blood cell (WBC) values for the following:

  • Abbott CELL-DYN® 3200
  • Sapphire® and Ruby®
  • Beckman Coulter® * LH 750/LH 755, LH 780 and UniCel® DxH 800
  • Sysmex® XE-2100, XE-5000, XT-2000i, XT-1800i, and XT-4000i instruments.
  • Two-part WBC differential assay values are also provided for the Sysmex XE-5000 and the XT-4000i.


  • 75-day closed-vial stability
  • 30-day open-vial stability
