role of serum creatine kinase as a marker for tubal pregnancy

ABSTRACT

There has been a great deal of interest to find a biochemical marker for tubal pregnancy which can be employed as a single randomly timed assay. The role of creatinekinase [CK] as a marker for tubal pregnancy has been evaluated in a prospective controlled study. We compared CK levels in the study group of 31 patients with tubal pregnancy and two control groups. 31 patients having missed abortion and 31 patients with normal pregnancy at comparable gestational age. CK level was > 50 IUIL. in all patients with tubal pregnancy, significantly higher than the level in either of the two control groups [P< 0.01]. We conclude that CK can serve as an additional diagnostic tool in the diagnosis of tubal pregnancy
