Evaluating the popularity of the Cys-C kit, we highlight the largest user of our company's product, the Hengyang Maternal and Child Health Care Hospital (Hengyang Children's Hospital), established in 1953. This comprehensive three-level A hospital integrates maternal and child health care, medical treatment, teaching, and scientific research. The hospital annually uses hundreds of boxes of our Cys-C kit, making it our largest user. Since March 5, 2018, the hospital has started using the 3V Cys-C kit, which works seamlessly with the Hitachi 7180 biochemical analyzer from Japan, providing accurate test results for the hospital and patients. In June 2020, our sales director conducted a follow-up on the usage of the Cys-C kit, and the biochemical group leader, Teacher Ouyang, highly praised the product: 1) The 3V Cys-C kit has good quality and excellent clinical compliance; 2) It has excellent stability, requiring no recalibration for a long time after calibration; 3) The packaging is exquisite; 4) The after-sales service is timely; 5) The price is reasonable; 6) Overall, the product is absolutely top-notch in the industry. The hospital previously used products from Japanese companies such as Nihon Kogaku and Mitsui.
