OBJECTIVE: To evaluate the ability of Creatine phosphokinase (CPK) levels and CPK-MB proportion to differentiate between extra and intrauterine of very early gestations with unknown location. MATERIALS AND METHODS: The study is case-control. CPK levels and CPK-MB proportion in 51 women with extrauterine pregnancies were compared to those in 28 women with early intrauterine pregnancies. RESULTS: No significant difference was found between women with extrauterine pregnancies and early intrauterine pregnancies in the levels of CPK (80.9 ± 62.1 vs. 74.9 ± 51.5; p = 0.66) and CPK-MB proportion (16.2 ± 10.1% vs. 15.1 ± 11.1%; p = 0.86). CONCLUSION: CPK and CPK-MB proportion determinations do not contribute to the clinical differentiation between early intra and extrauterine pregnancies.
