Measurement of plasma renin activities in four separate quality control pools showed no change when measured by radioimmunoassay after being individually stored at -20 degrees C for up to fifteen months, validating their use as long-term quality controls. These results contradict those reported by some authors.
在四个单独的质量控制样本组中测量血浆肾素活性,当它们在-20℃下单独储存长达15个月后通过放射免疫测定法测量时,未发现变化,这证实了它们可作为长期质量控制样本使用。这些结果与一些作者报道的结果相矛盾。
