Cell-Chex®

Cell-Chex is a multi-level manual cerebrospinal and body fluid control for evaluating the accuracy and precision of hemacytometer RBC and WBC counts, urate and CPPD crystal identification and manual WBC differential procedures. It is the only manual body fluid control that contains crystals to aid in crystal identification in synovial fluid samples.

Cell-Chex® multi-level manual cerebrospinal and body fluid control
 

Product Description

Cell-Chex is a cerebrospinal and body fluid manual procedural control for red blood cell (RBC) and white blood cell (WBC) counts, urate and CPPD crystal identification and white blood cell differentiation. The white blood cells in Cell-Chex are human to better resemble patient samples. When stained in the same manner as a patient sample, the technologist can differentiate granulocyte, lymphocyte and monocyte populations. The differential assay offers polymorphonuclear and mononuclear values and 5-part white cell differential values.

Benefits

  • Helps clinical laboratories meet quality requirements for manual body fluid analysis
  • Validates the entire cell qualification and quantification procedure
  • Easy to use, as it looks similar to a patient sample
  • Long shelf life reduces the number of shipments and associated costs
  • Access to STATS®, a free interlaboratory quality control program with peer group data comparison and online submission

Superior cell morphology versus competitors

Streck Cell-Chex contains biconcave RBCs and five types of morphologically distinct WBCs. Cell-Chex RBCs and WBCs are easy to differentiate and have morphology that is representative of fresh patient samples, unlike other available body fluid controls on the market.

Superior cell morphology versus competitors

Accuracy and precision of hemacytometer WBC and RBC counts

Consistent morphology of stabilized cells makes WBCs and RBCs easy to differentiate, ensuring accurate and precise counts on hemacytometers. Level 1-CC (CPPD Crystals) and Level 1-UC (Urate Crystals) have lower assayed cell counts, whereas Level 2 has higher assayed cell counts.

5-part manual WBC differentials

Cell-Chex WBCs are stabilized human cells. When stained in the same manner as patient samples, stabilized Cell-Chex WBC morphology resembles fresh patient WBCs, enabling accurate 5-part differential identification.

Urate and CPPD crystal identification

Cell-Chex is the only manual body fluid control that contains crystals for identification in synovial fluid samples. Real CPPD and urate crystals can be accurately differentiated based on morphology and polarized light microscopy.

Good product, consistent and easy to use.

“Great product. We needed to start running a hemocytometer/cytocentrifuge control for manual cell counts and differentials. This is now required by our accrediting agency. We are pleased with the ease of use and assayed values that ensure our technical staff is performing testing accurately.”
