thanks for your query.
Triple marker test assesses the risk of the fetus having chromosomal disorders - specifically Trisomy 21
( downs syndrome ), Trisomy 13 and Trisomy 18.
It is a screening test, and based on the risks calculated by the test, further testing and confirmation by amniocentesis
( karyotyping ) is recommended.
if you have missed the test, go for the further advised tests as recommended, and do not stress
yourself out over this one particular test.
