Abstract
Screening tests for Down's syndrome are carried out at different gestational ages. Because of fetal loss, crude estimates of their detection rates cannot be directly compared. We present methods for estimating the true detection rates along with their standard errors. This enables a proper statistical comparison of the true detection rates of tests carried out, for example, in different trimesters.
