New whole-blood quality control verifies accuracy.
The CD4 Count is a whole-blood quality control for verifying the accuracy of the BD FACSCount flow cytometer. The easy-to-read CD4 assay includes absolute counts and percent positive ratios on the cellular populations of CD3, CD4, and CD8 T-lymphocytes. These parameters are used in the diagnosis and treatment of HIV/AIDS patients. In addition, CD4 Count's clinically relevant levels of CD4 cells help clinicians evaluate the instrument's ability to read both normal and depressed levels. This product offers a 30-day open-vial stability, which allows labs to run the control every day, saving money. The 90-day closed-vial stability means fewer orders and reduced shipping costs.
