The rise in alkaline phosphatase activity has been studied after reconstitution of 16 commercial preparations of lyophilised quality control material. The effects of storage temperature and analytical method on the rise in activity have also been studied, with a view to producing a reconstitution protocol suitable for recommendation to participants in external quality control surveys. Great differences were found in the magnitude of this rise in activity; these differences can be reduced to negligible levels if the material is mixed for 30 minutes at ambient temperature after reconstitution and then stored for not more than 4 hours at 4 degrees C before assay.
在对16种市售冻干质量控制材料制剂进行复溶后，研究了碱性磷酸酶活性的升高情况。还研究了储存温度和分析方法对活性升高的影响，以期制定出适合推荐给外部质量控制调查参与者的复溶方案。发现这种活性升高的幅度存在很大差异；如果复溶后在室温下混合30分钟，然后在4℃下储存不超过4小时再进行测定，这些差异可降至可忽略不计的水平。
