摘要 目的了解溶血及血标本放置时间对血清甲胎蛋白(AFP)、游离β绒毛膜促性腺激素(free-β-hCG)测定有无影响。方法在溶血前后分别应用酶联免疫吸附方法(ELISA)测定64名孕妇血清AFP及free-β-hCG浓度;于采血后30m in、1h、2h及3h应用酶联免疫吸附方法(ELISA)分别测定22名孕妇血清AFP及free-β-hCG浓度。结果溶血前后测定血清AFP的浓度无显著性差异;但溶血后free-β-hCG的浓度显著高于溶血前;采血后30m in、1h、2h及3h测定血清AFP及free-β-hCG的浓度无显著性差异。结论溶血对free-β-hCG的测定有一定影响,但对于AFP无明显影响;血标本短时间放置对血清AFP及free-β-hCG的测定无明显影响。
