Serum Creatine Kinase in Tubal and Normal Pregnancy

Abstract

Objective To compare the serum creatine kinase level between tubal pregnancy and normal pregnancy.

Subjects and methods One hundred and forty-six pregnant women who had no history of cardiac disease or muscular disease or injury attending the Obstetrics and Gynaecology Department between 1st July 1994 and 30th June 1995 were recruited in this study. They were classified into two groups as fifty-five women with tubal pregnancy and ninety-one normal pregnant women. Serum creatine kinase of all subjects were measured by Rosalki's method before any procedures or treatments.

Main outcome measures Mean and standard deviation of serum creatine kinase.

Results The mean (+ standard deviation) in tubal pregnancy group was significantly higher than in normal pregnancy group (64.47 † 35.62 and 43.40 † 12.36 IU/L respectively, P = 0.000). Conclusion There was a significant difference in the mean serum creatine kinase between tubal and normal pregnancy. This finding indicates that the measurement of serum creatine kinase level may be useful for early diagnosis of tubal pregnancy.
