摘　　要：本文采用两种唾液酸测定方法,比较了正常人群体(386例)血清唾液酸(SA)的吸光度、含量。结果表明,方法一测定的平均吸光度为A=0.15±0.028(相应的SA含量为1.31±0.251mmol/L),位于光度计准确区域以外;方法二测定的平均吸光度A=0.24±0.030(相应的SA含量为2.13±0.272mmol/L),位于光度计准确区域之内。两种方法测定386例正常人血清平均吸光度间、平均含量间有非常显著的统计学差异(P<0.01)。特别是在血清唾液酸增高的肿瘤患者血清测定时,方法二优于方法一。Objective： To compare the absorptivities （A） of 386 normal human serumwith two different tests, contents too. Results ： （ 1 ） The average A was 0. 15 ± 0. 028 with method I （ corresponding content was 1.31 ± 0. 251 mmol/L）, it is out of the standard test range （0. 2 ～0. 85） of Photometer; compare to this, A was 0. 24 ±0. 030 （ corresponding content was SA =2. 13 ± 0. 272mmoL/L） with method Ⅱ wh/ch is in the required range, the average absorptivity of serum from 386 normal human serum through two methods revealed clear difference （ P 〈 0. 01 ） . （2） The results from method Ⅱ were more stable and relable than method Ⅰ when test serum from tumor patients.
