ABSTRACT
Objective To investigate the levels of serum AFP and CEA in healthy physical examination people and their sexual difference.Methods (1 )Healthy physical examination people were divided into the group A(510 males)and group B(477 fe-males);(2)these two groups were subdivided into the group A1 (<40 years old),A2 (40 - <50 years old),A3 (50 - <60 years old),A4(60-<70 years old)and A5 (70 -87 years old),and group B1 (<40 years old),B2(40 -<50 years old),B3 (50 -<60 years old),B4(60-<70 years old)and B5(70-87 years old).The serum AFP and CEA in 987 healthy physical examination peo-ple were measured by the electrochemiluminesence immunoassay,and then the detection results were compared among various groups.Results (1)The detection results of serum AFP and CEA had statistically significant differences between the group A and B (P <0.01);(2)there was no statistical differences among the group A and among the group B.Conclusion The serum AFP and CEA levels in healthy physical examination people in the local area have difference between males and females,which in males are significantly higher than those in females,indicating that the reference range of AFP and CEA should be repectively established ac-cording to different sexes;while the serum AFP and CEA levels have no differences among various age groups in males and fe-males.
