Cell-Chex Auto is a tri-level body fluid control for evaluating the accuracy of and precision of hematology analyzers that measure automated blood cell counts in patient body fluid samples. Cell-Chex Auto tests the instrument’s reportable range at the lower linearity limits that standard CBC controls and calibrator material fail to assess. Assay includes a two-part WBC differential for the Sysmex XE-5000 and XT-4000i analyzers. Cell-Chex Auto is available in plastic cap-pierceable vials which allow for autosampling by a hematology analyzer. Cell-Chex Auto is compatible with Abbott, Beckman Coulter, Siemens Healthcare Diagnostics and Sysmex hematology analyzers.Cell-Chex Auto is a tri-level body fluid control for evaluating the accuracy of and precision of hematology analyzers that measure automated blood cell counts in patient body fluid samples.
