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.

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

Cell-Chex controls for red blood cell (RBC) and white blood cell (WBC) counts, urate and CPPD crystal identification and white blood cell differentiation. It is comprised of a patient-like mix of intact RBCs, urate and CPPD crystals and human white blood cells. When stained in the same manner as a patient sample, Cell-Chex can be used to control for the differentiation of granulocyte, lymphocyte and monocyte populations.

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.”
