title: Exclusion of chromosomal mosaicism in prenatal diagnosis.
abstract: For use in prenatal diagnosis, tables were prepared giving the number of metaphases or clones, respectively, which must be analysed in order to detect fetal mosaicism of a given degree (= percentage of the aberrant cell population) or higher with at least 95% or 99% probability. Different tables are provided for the two techniques of chromosomal preparation: the colony method and the flask method.
