For monitoring the immunosuppressive drug cyclosporin A by radioimmunoassay (Sandoz Ltd.) we propose a simple method of sampling in which 20 microL of capillary blood is dried on filter paper. Patients can collect their own samples and mail or bring them to the laboratory. Results for such samples, and their variability, correspond to those for conventional methods of sampling (collection of venous or capillary blood into buffer). Capillary blood can be stored on paper at room temperature for more than four weeks with no effect on assay results.
对于通过放射免疫分析法（山德士有限公司）监测免疫抑制药物环孢素A，我们提出一种简单的采样方法，即取20微升毛细血管血在滤纸上干燥。患者可以自行采集样本并邮寄或送至实验室。此类样本的检测结果及其变异性与传统采样方法（将静脉血或毛细血管血采集到缓冲液中）的结果相符。毛细血管血可在滤纸上于室温下保存四周以上，且对检测结果无影响。
