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

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.
