ＡＣＬ测定仪做凝血测定时，比浊通道用参比液做光学比浊，其用量甚微，每盘检测约需２００μｌ，而大量的参比液是用于对仪器测试管道和加样针等的清洗。目前国内没有生产参比液，不能自配，进口试剂又较为昂贵，若按仪器操作使用，耗资过多。考虑到绝大部分情况下是用于清洗 When the ACL analyzer is used for coagulation assay, the turbidimetric channel is used for optical turbidimetry with the reference solution. Its amount is very small. Each assay requires about 200 μl, and a large amount of reference solution is used to test the instrument and pipetting needle, etc. Cleaning. At present, there is no production of reference solution in the country and it cannot be self-provisioned. The imported reagents are relatively expensive. If the instrument is used and operated, it will cost too much. Considering that most of the time is for cleaning
