Hello and welcome to HCM,

The ultrasound report revealing nuchal fold thickness suggests Down syndrome.
The confirmatory test for Down syndrome is triple test and quadruple test.
The triple test measures three parameters- HCG, AFP and estradiol.
The quadruple test adds another parameter called PAPPA.
This test is readily available at all labs.
You need to visit a gynae-obs specialist for further work up.
I am sure there are many gynae-obs specialist in the city of Kolkatta.

Get the test done at the earliest so that if positive, further management can be done at the earliest.

Thanks and take care.
Dr Shailja P Wahal
