对献血者血液的筛查是安全输血的重要措施,尤其对ALT、HBsAg、抗-HCV和梅毒抗体的4项检测是预防和控制输血传播肝炎和梅毒的主要手段。笔者从1992年12月起对上海市全部临床供血和生产用血浆的32个血站(含市郊和江苏、浙江、安徽、河南等地的采供血机构)ALT、HBsAg、抗-HCV、梅毒4项检测,开展了室间质量调查评价,现报告于下。1 情况调查和举办学习班 1992年首先对各血站发送调查表并派人作现场调查,内容包括检验室环境、仪器设备、技术人员水平、检验项目、试剂来源、操作方法、希望和要求等。分别举办了血站业务站长及检验室负责人学习班,统一试剂(免疫试剂)及操作方法,详细介绍开展质量控制的意义和具体步骤,使参加者在思想和理论上充分认识到血站
The screening of blood from blood donors is an important measure for safe blood transfusion. In particular, the four tests for ALT, HBsAg, anti-HCV and syphilis antibodies are the main means to prevent and control transfusion-transmitted hepatitis and syphilis. From December 1992, the author performed 32 blood stations for all clinical blood supply and production plasmas in Shanghai (including suburbs and blood collection and distribution institutions in Jiangsu, Zhejiang, Anhui and Henan) ALT, HBsAg, anti-HCV, and syphilis 4 Item tests, conducted inter-room quality survey evaluation, are reported below. 1 Situation investigation and organization of a study class In 1992, firstly, a questionnaire was sent to each blood station and field investigations were conducted. The contents included laboratory environment, equipment, technician level, inspection items, reagent source, operation method, hope and requirements, etc. . The workshops for the head of the blood station and the person in charge of the laboratory were held to unify the reagents (immune reagents) and methods of operation. The significance and specific steps for quality control were introduced in detail, so that the participants fully understood the blood station both in thought and in theory.
