我院于1982年4月19日为一患者作非蛋白氮检查时,因在推注50％葡萄糖20毫升后,即从原针头取血2毫升作标本,经海登氏改良法制备无蛋白滤液,用亚硒酸消化、纳氏试剂显色法连续数次均失败。后检测标本血糖为482毫克％。次日,空腹抽血复查,血糖为100毫克％,仍用前法始测出非蛋白氮为60毫克％。由此可见,高血糖对非蛋白氮的测定有一定影响,临床测定非蛋白氮时,应予注意。
Our hospital on April 19, 1982 for a non-protein nitrogen test for patients, because after the injection of 50% glucose 20 ml, that is, from the original needle 2 ml blood samples for the preparation by Hayden improved protein-free The filtrate, digested with selenite, Nessler reagent colorimetric method failed several times in a row. Post-test specimen blood glucose was 482 mg%. The next day, fasting blood review, blood glucose was 100 mg%, still using the former method to detect non-protein nitrogen was 60 mg%. Thus, high blood sugar has a certain impact on the determination of non-protein nitrogen, clinical determination of non-protein nitrogen, should be noted.
