The use of boric acid-impregnated filter paper has proven to be a useful and reliable means of absorbing capillary blood samples for determining glucose concentration. In this method a circular piece of filter paper (6.36 mm radius) infiltrated with the blood sample is punched out with a commercially available punch, glucose is eluted from the filter paper with a haemolyzing solution and subsequently glucose concentration determined by whatever method is available. Using the hexokinase method, this gives satisfactory precision and unimpaired accuracy. It compared well with the frequently used sampling with capillary tubes, correlating with an r value of 0.9932. The sample, obtained as described, is insensitive to light, temperature, humidity and time interval until measurement. Glucose concentration remains stable under various conditions for at least four weeks.
事实证明，使用浸有硼酸的滤纸是吸收毛细血管血样以测定葡萄糖浓度的一种有用且可靠的方法。在该方法中，用市售打孔器从浸有血样的圆形滤纸（半径6.36毫米）上冲出纸片，用溶血溶液从滤纸上洗脱葡萄糖，随后用任何可用方法测定葡萄糖浓度。采用己糖激酶法，该方法具有令人满意的精密度且准确性不受影响。它与常用的毛细管采血法相比效果良好，相关系数r值为0.9932。按所述方法获得的样本对光、温度、湿度和测量前的时间间隔不敏感。在各种条件下，葡萄糖浓度至少四周保持稳定。
