  • Method of determining pregnancy toxemia
    Patent number: 7759080
    Abstract: It is intended to provide a method of detecting the onset of pregnancy toxemia whereby the onset risk of pregnancy toxemia can be adequately evaluated. Namely, a method of detecting the onset of pregnancy toxemia in a pregnant mammal which comprises the measurement step of measuring the concentration of angiopoietin-2 in a body fluid, the comparison step of comparing the angiopoietin-2 concentration obtained in the above measurement step with a normal level, and the judgment step of judging the presence or absence of the onset risk of pregnancy toxemia based on the results of the above comparison step. In the judgment step, it may be considered that the patient has a risk of the onset of pregnancy toxemia in the case where the angiopoietin-2 concentration obtained in the measurement step is lower than the normal level.
