[The preclinical diagnosis of threatened abortion and late gestosis in pregnant women with normal body weight and obesity].

Measurements of blood serum phosphatidyl inosites in pregnant women with normal body mass and with obesity in whom pregnancy ran normal or pathological course showed that phosphatidyl inositol levels increased 2-3-fold in case of threatened miscarriage and decreased 2-3-fold if symptoms of late gestosis appeared (an abnormal gain in body mass) as compared to their levels in women with an uneventful course of pregnancy. Phosphatidyl inositol levels were higher in obese women that in those with normal body mass, no matter what the pregnancy course was.
