R&D Systems™ HemoScreen Linearity Kit
Customized HemoScreen Linearity Kit includes 5 levels for calibration verification.
Streck CD-Chex™ CD34
CD-Chex CD34 is a three-level process control for enumerating CD34 positive cells by flow cytometry. It requires no dilution and provides reference values similar to levels found in bone marrow, cord blood and mobilized patient samples.
Streck CD-Chex TdT™ Plus Assay
CD-Chex TdT Plus is a positive procedural control that provides reference values for TdT, CD1a, CD2, CD4, CD5, CD7, CD8, CD34 and cytoplasmic CD3. This control contains several markers designated as rare flow antigens by CAP.
Streck Retic-Chex™ Linearity
Retic-Chex Linearity for BC is designed to establish the reportable range and linearity of Beckman Coulter™ hematology analyzers that report the reticulocyte parameter.
Streck Cell-Chex™ Auto Body Fluid Cell Count Control
Cell-Chex Auto is an automated body fluid cell count control for Abbott™, Beckman Coulter™, Siemens Healthineers™ and Sysmex™ hematology analyzers. With this tri-level control, you can verify instrument accuracy at the lower WBC and RBC reportable range limits that standard CBC controls and calibrator material fail to assess.
Streck Cell-Chex™ Auto Body Fluid Cell Count Control
Cell-Chex Auto is an automated body fluid cell count control for Abbott™, Beckman Coulter™, Siemens Healthineers™ and Sysmex™ hematology analyzers. With this tri-level control, you can verify instrument accuracy at the lower WBC and RBC reportable range limits that standard CBC controls and calibrator material fail to assess.
Streck Cell-Chex™ Cell Body Fluid Control
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.
Streck Cell Preservative™
Cell Preservative is an easy-to-use liquid preservative that maintains white blood cell integrity and allows CD markers to be measured through flow cytometric analysis. Cell Preservative stabilizes peripheral and cord blood samples, surgical tissue samples, bone marrow and fine needle aspirates for up to 7 days prior to analysis by flow cytometry.
Streck A1c-Cellular™ Linearity Material
A1c-Cellular Linearity is a ready-to-use linearity product that tests the entire HbA1c procedure, including the lysing of the red blood cell. It is assayed on the top HbA1c chemistry analyzers and provides instrument-specific target values and expected ranges.
