该材料取代了编码为96/668的前列腺特异性抗原(免费)第一国际标准(IS),该标准已被广泛用于校准免费PSA的免疫测定。第一个IS的库存量很低,世界卫生组织生物标准化专家委员会(ECBS)认识到(2014年)需要更换IS。PSA的第一个IS含有来自精浆的游离PSA,指定含量为每瓶1微克PSA(1)。第二届世界卫生组织PSA(免费)信息系统(编号17/102)由非复合、精浆来源的游离PSA制备,于世界卫生组织ECBS第69次会议(2018年)上确定。该材料取代了已停产的96/668 PSA(免费)的第一个IS。 NIBSC17/102

该制剂含有人类来源的材料,其最终产物或来源材料经过测试,发现HBsAg、抗HIV和HCV RNA呈阴性。与所有生物来源的材料一样,这种制剂应被视为对健康有潜在危害。应根据您自己实验室的安全程序使用和丢弃它。此类安全程序应包括佩戴防护手套和避免产生气溶胶。打开安瓿或小瓶时应小心,以避免割伤。 可溯源国际标准物质人游离前列腺特异性抗原

The material replaces the 1st International Standard (IS) for Prostate Specific Antigen (free), coded 96/668, which has been widely used for the calibration of immunoassays for free PSA. Stocks of the 1st IS are low and the WHO Expert Committee on Biological Standardization (ECBS) recognized (2014) the need for a replacement IS. The 1st IS for PSA contained seminal plasma-derived free PSA and had an assigned content of 1 µg PSA per vial (1). Prepared using non-complexing, seminal plasma-derived free PSA, the 2nd WHO IS for PSA (free), coded 17/102,was established at the 69th Meeting of WHO ECBS (2018). This material replaces the 1st IS for PSA (free), 96/668, which is discontinued.

The preparation contains material of human origin, and either the final product or the source materials, from which it is derived, have been tested and found negative for HBsAg, anti-HIV and HCV RNA. As with all materials of biological origin, this preparation should be regarded as potentially hazardous to health. It should be used and discarded according to your own laboratory’s safety procedures. Such safety procedures should include the wearing of protective gloves and avoiding the generation of aerosols. Care should be exercised in opening ampoules or vials, to avoid cuts.
