Human prenatal diagnosis
Advances in the field of prenatal diagnosis have been rapid during the past decade. Moreover, liberal use of birth control methods and restriction of family size have placed greater emphasis on optimum outcome of each pregnancy. There are many prenatal diagnostic techniques of proven value; the risks, including false negatives and false positives, are known. With the rapid proliferation of new and experimental techniques, many disorders are potential diagnosable or even treatable; however, risk factors are unknown and issues relating to quality control have not been resolved. These problems are readily appreciated in the dramatic new techniques involving recombinant DNA, chorion villus sampling, and fetal surgery. Unfortunately, clinicians may not appreciate the difficulties that may also be encountered in the more mundane prenatal diagnostic tests such as ultrasonography or enzymatic testing. The aim of this volume is to clarify and rationalize certain aspects of diagnosis, genetic counseling, and intervention. New and experimental techniques are presented in the light of current knowledge.
