17 weeks 4 days. In first trimester prenatal screening test or double marker test trisomy 21 was screen positive. it was 1:170.doctor told for amniocentesis.then we did Amniocentesis . Now Amniocentesis report is normal.We just wanted to know whether these double marker test and amniocentesis were at all necessary? In anomaly scan which is done after 18 weeks there is the option of detecting abnormality in fetus , then why these tests? Are these at all necessary or these are just buisness of doctor and the labs?Pls reply doctor. And share experiences if anyone went through these tests.
@616fdb6bee57850013f09995 but our doctor didn't tell to do quadruple or tripple marker test.he told amniocentesis as double marker test result was screen positive.

It is a relief that your aminoses came normal otherwise with a probability of 1 is to 170 the risk is high high of getting a trisomy positive these test are extremely sensitive and important if the normal markers debate from normal in your early test such as the first screening is nuchal translucency and nuchal fold thickness if both of these are not normal then the doctor will advise you quadruple or triple marker and if in both these test the consolidated risk calculated according to age and and the core mom values are high then you will again be advised of amino or nipt test.
