ESR-Chex is a two-level hematology control used to monitor erythrocyte sedimentation rates. It provides superior sed-rate accuracy, reacting to physical factors such as benchtop vibration, temperature and tube angle, and alerts the technologist to possible problems that may affect the accuracy of patient results.
ESR-Chex is manufactured from human red blood cells and is assayed for the most frequently used sedimentation rate tubes in conjunction with the Classical Westergren, Modified Westergren, and Wintrobe methods. ESR-Chex is used in the same manner as a patient sample.
