Summary: A talk by Professor T. Chard from St. Bartholomew's Hospital Medical College. The following summary accompanies the videocassette: Biochemical tests of fetoplacental well-being depend on the measurement in the mother of materials which differ from those in the nonpregnant adult. The two most popular tests at the present time are measurement of oestrogens and hPL. The main problems with these tests are the lack of information on the biochemical role of these materials and the very substantial overlap between normal and abnormal. Despite this, however, they have been shown to be of great value in a number of clinical situations and, in particular, in the diagnosis of intrauterine growth retardation. Recent developmetns include the introduction of new specific fetoplacental products, the evaluation of specific tests for placental transfer, and the use of biochemical tests as a screening procedure in all pregnancies. 6 segments.
