The PRECIL Series, originally developed by Beijing Precil and now associated with Mindray, comprises specialized coagulation analyzers and hemorheology analyzers for clinical laboratory testing. Coagulation analyzers measure PT, APTT, fibrinogen, TT, D-dimer, factor assays, and thrombophilia markers for diagnosing bleeding disorders, monitoring anticoagulant therapy, and assessing liver function. Hemorheology analyzers measure whole blood viscosity, plasma viscosity, erythrocyte aggregation, and deformability for evaluating hyperviscosity syndromes, sickle cell disease, diabetes, and cardiovascular disorders. The series includes specialized cleaning solutions and reagents (such as PLS cleaner) for maintaining analyzer performance and ensuring accurate results. Features include automated sample processing, color touchscreen interface, LIS connectivity, and comprehensive quality control programs. Primary clinical applications include coagulation testing for preoperative assessment, anticoagulant monitoring, DIC diagnosis, thrombophilia workup, and hemorheology assessment for conditions affecting blood flow. Essential laboratory instrumentation for hematology, coagulation, and specialized testing in hospital laboratories, reference laboratories, and research facilities.
