摘要 目的探讨亲和层析法、高效液相色谱法(HPLC)、免疫比浊法和酶法检测糖化血红蛋白A1c(HbA1c)对游离胆红素(F-Bil)、结合胆红素(C-Bil)、血红蛋白(Hb)和乳糜微粒(CM)的抗干扰能力。方法收集EDTA-K2抗凝新鲜血,制备HbA1c10.4%和6.2%的高、低浓度标本,对4种方法检测HbA1c进行干扰实验。结果 4种干扰物对亲和层析法、HPLC法检测HbA1c无干扰。CM≥15 000 FTU时,免疫比浊法测定HbA1c有干扰。F-Bil、C-Bil≥121.3μmol/L时,酶法检测高浓度HbA1c有干扰;F-Bil≥196.8μmol/L、C-Bil≥121.3μmol/L时,酶法检测低浓度HbA1c有干扰。结论酶法检测HbA1c抗胆红素干扰能力有待改进,应剔除黄疸标本。免疫比浊法则应避免高CM标本。
