ESR-Chex is a two-level hematology control used to monitor erythrocyte sedimentation rates. ESR-Chex is manufactured from human red blood cells, and verifies the precision and accuracy of manual and automated methods. ESR-Chex is assayed for the most frequently used sedimentation rate tubes in conjunction with the Classical Westergren, Modified Westergren and Wintrobe methods. Automated and modified procedures do not require removal of sodium citrate, and ESR-Chex is used in the same manner as a patient sample. The control has 95-day open-vial stability at 18°-25°C, and 12-month closed-vial stability at 2°-10°C.
