In brief: Not very.
The triple screen will detect about 70% of mothers carrying babies with down syndrome, but it is only a screening test and does not diagnose down syndrome.
There are many false positive tests ("abnormal" tests in women who are carrying babies that do not have down syndrome). A newer blood test for fetal dna in the mother's blood can actually diagnose down syndrome in women who are at higher risk.
